One of the objectives of the ME Senior Lab Course at Rose-Hulman (ME421) is to have students experience a 'test and refine' cycle. During the first half of the ten-week quarter, ME421 students select an experimental project, perform an experimental procedure to obtain data, and present results to the team of instructors. The latter half of the course is spent performing refined experimental work based on instructor feedback.
One of the selected projects during the most recent offering of the course was based on the study of meteorites. A student team embarked on a project of experimentally heat treating meteorite samples, and correlating the grain growth results to similarly heat treated steel specimens. The theory that the students sought to demonstrate was based on a determination of the activation energy for grain growth in meteorites.
Using meteorites in a Mechanical Engineering curriculum is shown to be a cross-disciplinary experience. During the course of the quarter, students interacted with faculty from the Physics, Chemistry and Materials disciplines, as well as within their home Mechanical Engineering Department. Challenges involved determining which heat treatment time and temperature regime give measurable grain growth, and determining suitable polishing and etching procedures for the samples. Recommendations for future course offerings are given.
1. Introduction – About ME 421, Mechanical Engineering Laboratory
Mechanical Engineering Laboratory is a required two-credit course for senior-level students in the ME Department at Rose-Hulman Institute of Technology (RHIT). One of the primary objectives of the course is to have students experience a 'test and refine' cycle. Student teams select an experimental project, perform a literature search, conduct research and report results within the first half of the quarter. After receiving instructor feedback at the formal project review (mid-quarter, at five weeks), the student teams refine their experimental efforts and report the finalized results in a professional-quality written report. The course deliverables are an oral presentation at mid-quarter and a comprehensive written report at the end of the quarter.
