Perspection is an art exhibition dealing with the ideas of perspective and perception, as it relates to observation of artwork. As a viewer, art is seen as an inanimate thing, however, so much time is spent in the conception and execution of a piece that it begins to take on a life of its own. This thesis is the exploration of how art has the power to come alive, creating conversations with a viewer while showing them another way to observe the world around them.

Corrosion of the US Steel Industry: Macroeconomic Competition and Productivity

The US steel industry experienced a great decline between 1950-1985. Influenced by several government policies, the industry was first cartelized during the great depression and then subjected to an extremely powerful organized labor force. Due to high demand between and during WWII and the Korean War, the industry expanded capacity using existing technologies. Simultaneously, organized labor was able to secure increased wages and large severance costs for firms that decided to shutdown existing steel mills. In the post war years this prevented firms from innovating through investing in newer, more efficient, technologies. Eventually US steel firms had no advantage against foreign producers who could produce steel cheaper and more efficiently.

Analysis of pulsed gas metal arc welding (P-GMAW) heat input on UNS-S32101 lean duplex stainless steel

This report presents the effects and analysis of the effects of Pulsed-Gas Metal Arc Welding's (P-GMAW) on Lean Duplex stainless steel. Although the welding of Duplex and Super Duplex Stainless steels have been well documented in both the laboratory and construction industry, the use of Lean Duplex has not. The purpose for conducting this research is to ensure that the correct Ferrite-Austenite phase balance along with the correct welding procedures are used in the creation of reactor cores for new construction nuclear power generation stations. In this project the effects of Lincoln Electrics ER-2209 GMAW wire are studied. Suggestions and improvements to the welding process are then proposed in order to increase the weldability, strength, gas selection, and ferrite count. The weldability will be measured using X-Ray photography in order to determine if any inclusions, lack of fusion, or voids are found post welding, along with welder feedback. The ferritic point count method in accordance with ASTM A562-08, is employed so that the amount of ferrite and austenite can be calculated in the same manor that is currently being used in industry. These will then be correlated to the tensile strength and impact toughness in the heat-affected zone (HAZ) of the weld based on the ASTM A923 testing method.

The application of temper-etch inspection to micromilled AISI 4340 steel specimen

Micromachining has seen application growth in a variety of industries requiring a miniaturization of the machining process. Machining at the micro level generates different cutter/workpiece interactions, generating more localized temperature spikes in the part/sample, as suggested by multiple studies. Temper-etch inspection is a non-destructive test used to identify `grind burns' or localized over-heating in steel components. This research investigated the application of temper-etch inspection to micromachined steel. The tests were performed on AISI 4340 steel samples. Finding, indications of localized over-heating was the primary focus of the experiment. In addition, change in condition between the original and post-machining hardness in the machined slot bottom was investigated. The results revealed that, under the conditions of the experiment, no indications of localized over-heating were present. However, there was a change in hardness at the bottom of the machined slot compared to the rest of the sample. Further research is needed to test the applicability of temper-etch inspection to micromilled steel and to identify the source of the change in hardness.
