Abstract Details

2015, Master of Science in Engineering, University of Akron, Civil Engineering.
In this thesis report an attempt is made to present and briefly discuss the specific influence of exposure, by way of immersion, to four different environments, pH+Salt, salt, pH and distilled water, for four chosen time period of one-week, two-weeks, three-weeks, and eight-weeks on the static (uni-axial tensile) and dynamic (impact) properties of two ferrous metals [i.e, 304L stainless steel, and alloy steel 4340 CF] and two non-ferrous metals [i.e., aluminum alloy 6061-T651 and aluminum alloy 7075]. Test specimens for both tensile tests and Charpy V-Notch impact tests on the as-provided material were precision machined and conformed to standards specified by the American Society for Testing Materials (ASTM). The pH and conductivity were measured using a pH meter and a conductivity meter. The pH and conductivity were measured in an attempt to establish the acidity-level or alkalinity-level of the chosen mediums. The impact toughness response and resultant fracture behavior of the four chosen metals, subsequent to their exposure, by way of immersion, for chosen time periods were studied over the temperatures range -180°C to +170°C. The tensile tests were performed in the room temperature (25oC), laboratory air (RH 55 pct.) environment. Final fracture behavior of the chosen metals was determined at both the macroscopic and fine microscopic levels. This was made possible following careful examination in a scanning electron microscope. After analyzing the data obtained it was observed that Salt medium was more corrosive among all the four environments and Distilled water was corrosion resistant medium. Steel was more corrosion resistant compared to Aluminum.
