Surface Mechanical Attrition Treatment (SMAT) of 7075 Aluminum Alloy to Induce a Protective Corrosion Resistant Layer

Description

This paper investigates Surface Mechanical Attrition Treatment (SMAT) and the influence of treatment temperature and initial sample surface finish on the corrosion resistance of 7075-T651 aluminum alloy. Ambient SMAT was performed on AA7075 samples polished to 80-grit initial surface roughness.

This paper investigates Surface Mechanical Attrition Treatment (SMAT) and the influence of treatment temperature and initial sample surface finish on the corrosion resistance of 7075-T651 aluminum alloy. Ambient SMAT was performed on AA7075 samples polished to 80-grit initial surface roughness. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) tests were used to characterize the corrosion behavior of samples before and after SMAT. Electrochemical tests indicated an improved corrosion resistance after application of SMAT process. The observed improvements in corrosion properties are potentially due to microstructural changes in the material surface induced by SMAT which encouraged the formation of a passive oxide layer. Further testing and research are required to understand the corrosion related effects of cryogenic SMAT and initial-surface finish as the COVID-19 pandemic inhibited experimentation plans.

Human Physiological Adaptations to Starvation and Caloric Restriction

Throughout history humans have had to adapt to changing conditions in order to survive. Food shortages are one of the major pressures that have shaped past populations. Because of this, the human body has many physiological adaptations that allow it to go extended periods of time consuming little to no food. These adaptations also allow the body to recover quickly once food becomes available. They include changes in metabolism that allow different fuel sources to be used for energy, the storing of excess energy absorbed from food in the forms of glycogen and fat to be used in between meals, and a reduction in the basal metabolic rate in response to starvation, as well as physiological changes in the small intestines. Even in places where starvation is not a concern today, these adaptations are still important as they also have an effect on weight gain and dieting in addition to promoting survival when the body is in a starved state.

Disclaimer: The initial goal of this project was to present this information as a podcast episode as a part of a series aimed at teaching the general public about human physiological adaptations. Due to the circumstances with COVID-19 we were unable to meet to make a final recording of the podcast episode. A recording of a practice session recorded earlier in the year has been uploaded instead and is therefore only a rough draft.

Obscenity: The Quick and Dirty

Zines have made space for queer, intersectional feminists to bring together academic and artistic knowledge in order to produce a message and inspire readers. In order to criticize the legal definition and practical execution of obscenity in the US, a visual component was a necessity. The use of a Zine allowed for a critical and humorous exploration of obscenity in US law and media. The Zine provides a visual analysis while the companion essay provides a critique of the zine and additional analysis. The Zine brings awareness to ways in which the legal historical objectification of black and native bodies contributed to the creation of modern obscenity laws. These laws are based on racist and sexist ideals of morality and create inherently flawed definitions of obscenity through personal bias. The flaws within the laws allow for exceptions in the legal definition of obscenity which normalizes the commodification of women's bodies. These laws and the exceptions present contribute to the dehumanization of and violence towards women as usefulness is deemed the most important factor when considering the use of women’s bodies in potentially obscene images and films.

Engineering an object means engineering the process that creates the object. Today, software can make the task of tracking these processes robust and straightforward. When engineering requirements are strict and strenuous, software custom-built for such processes can prove essential. The work for this project was developing ICDB, an inventory control and build management system created for spacecraft engineers at ASU to record each step of their engineering processes. In-house development means ICDB is more precisely designed around its users' functionality and cost requirements than most off-the-shelf commercial offerings. By placing a complex relational database behind an intuitive web application, ICDB enables organizations and their users to create and store parts libraries, assembly designs, purchasing and location records for inventory items, and more.

In this creative project, our goal was to establish a student lead service organization dedicated to raising money and awareness for a selected medical issue through an interactive carnival event. In doing so, we were able to identify the potential obstacles and pathways that are required for service organizations within Arizona State University. Our experience provides a guideline for future students looking to organize charitable events on campus. This paper discusses several essential skills for running a charitable student organization, including establishing a brand, managing finances, cultivating business relationships, and marketing the cause. It is our hope that future students can learn from our experience and find success in similar endeavors.

Can You See Me?: Stories to Fight Erasure

Description

There has been a recent push for queer fiction, especially in the young adult genre, whose focus is gay and lesbian relationships. This growth is much needed in terms of visibility and the furthering of acceptance, but there are still subjects within the LGBTQ+ community that need to be addressed, including bisexual, asexual, and non-binary erasure. There are many people who claim that these identities do not exist, are labels used as a stepping stone on one's journey to discovering that they are homosexual, or are invented excuses for overtly promiscuous or prudish behavior. The existence of negative stereotypes, particularly those of non-binary individuals, is largely due to a lack of visibility and respectful representation within media and popular culture. However, there is still a dearth of non-binary content in popular literature outside of young adult fiction. Can You See Me? aims to fill the gap in bisexual, asexual, and non-binary representation in adult literature. Each of the four stories that make up this collection deals with an aspect of gender and/or sexuality that has been erased, ignored, or denied visibility in American popular culture. The first story, "We'll Grow Lemon Trees," examines bisexual erasure through the lens of sociolinguistics. A bisexual Romanian woman emigrates to Los Angeles in 1989 and must navigate a new culture, learn new languages, and try to move on from her past life under a dictatorship where speaking up could mean imprisonment or death. The second story "Up, Down, All Around," is about a young genderqueer child and their parents dealing with microaggressions, examining gender norms, and exploring personal identity through imaginary scenarios, each involving an encounter with an unknown entity and a colander. The third story, "Aces High," follows two asexual characters from the day they're born to when they are 28 years old, as they find themselves in pop culture. The two endure identity crises, gender discrimination, erasure, individual obsessions, and prejudice as they learn to accept themselves and embrace who they are. In the fourth and final story, "Mile Marker 72," a gay Mexican man must hide in plain sight as he deals with the death of his partner and coming out to his best friend, whose brother is his partner's murderer.

This thesis evaluates the viability of an original design for a cost-effective wheel-mounted dynamometer for road vehicles. The goal is to show whether or not a device that generates torque and horsepower curves by processing accelerometer data collected at the edge of a wheel can yield results that are comparable to results obtained using a conventional chassis dynamometer. Torque curves were generated via the experimental method under a variety of circumstances and also obtained professionally by a precision engine testing company. Metrics were created to measure the precision of the experimental device's ability to consistently generate torque curves and also to compare the similarity of these curves to the professionally obtained torque curves. The results revealed that although the test device does not quite provide the same level of precision as the professional chassis dynamometer, it does create torque curves that closely resemble the chassis dynamometer torque curves and exhibit a consistency between trials comparable to the professional results, even on rough road surfaces. The results suggest that the test device provides enough accuracy and precision to satisfy the needs of most consumers interested in measuring their vehicle's engine performance but probably lacks the level of accuracy and precision needed to appeal to professionals.
