MAE T 205 Powder Metallurgy Laboratory (4)
This is a capstone course emphasizing hands-on laboratory experience in powder metallurgy. Students carry out routine engineering tests on powdered metal materials and document experimental data in a laboratory notebook. Each student is assigned a semester project and prepares a final written report and oral presentation on their findings. Class field trips give students direct exposure to local industries that use P/M technology.
The course begins with a brief introduction covering course requirements and lab safety rules. A review of technical writing is presented which addresses elements of effective workplace writing, technical business letters, resumes, cover letters, and use of the Penn State library. A general discussion and demonstration is given for various metal powder testing methods. This is based upon material presented in MAE T 203 taught in the third semester of the materials program. The student is referred to the published procedures described in the standard test methods for metal powders and powder metallurgy products established by the Metal Powder Industries Federation (MPIF). Supplementary material on stainless steel alloys is introduced since this type of powder is used for the in-class demonstrations by the instructor. Students are required to participate in a class exercise in characterizing a selected stainless steel powder. This exercise covers powder sampling, flow ability, apparent density, tap density, sieve analysis, average particle size and powder shape. The exercise also covers powder compaction behavior by requiring the students to fabricate transverse rupture specimens and measure the resulting green density associated with a given loading pressure. Each student learns how to record their data in their own laboratory notebook using a standard format. One unique feature of this course is the scheduled class field trips to nearby P/M industries and the particulate matter laboratory at State College.
A major turning point occurs when each student is assigned a semester project and allowed to work independently on their project for the remainder of the semester. This project requires that the student contact a vendor and order metal powder for evaluation. The student performs engineering tests on this powder and prepares a written report on their findings. An outline for the content and depth of discussion for written reports is provided by the instructor. The last scheduled day of class is used for student presentations on their semester project to peers and industry representatives.
Note : Class size, frequency of offering, and evaluation methods will vary by location and instructor. For these details check the specific course syllabus.
