MSE 440: Processing of Metallic Materials Instructors: Yuntian Zhu Office: 308 RBII Ph: 513-0559 ytzhu@ncsu.edu Lecture 1 Text book, Office hour, by appointment Department of Materials Science and Engineering 1

Course Description and Objectives see the Syllabus for more details Course Description (from Catalog): Fundamental concepts of solidification and their application to foundry and welding practices; metal forming concepts applied to forging, rolling, extrusion, drawing, and sheet forming operations; machining mechanisms and methods; powder metallurgy; advanced processing methods including rapid solidification and mechanical alloying. Course Objectives: By the end of the course, you should be able to do the following things: Understand the physical principles related to the processing of metallic materials such as solidification theory, metal forming theory, theory of chip formation in machining, etc. Be familiar with the common metal processing technologies both from classroom study and from field trips. Be able to optimize the design of processing variables to obtain sound material free from defects.   Department of Materials Science and Engineering 2

Testing and Grading No grade markup no matter how close Where are testing problems from? Underlined contents in the slides Homework assignments Quizzes/class discussions 440, 540-001 and 540-601 will be graded separately 540 will have more challenging testing problems Test 1 30% Test 2 30% Final 40% (The final is comprehensive) Ask students to think about it, and ask questions No grade markup no matter how close Targeted grade distribution: A: 15-25%, B: 30-40% Department of Materials Science and Engineering 5

Teaching style Active student participation in class A dice will be rolled to determine who participates 0.2% will be deducted if you are not present in the class to answer a quiz; 0.2% extra credit will be given if you give the right answer 0.2% extra credit will be given to a volunteer who gives the right answer No credit will be given or deducted if you give a wrong answer for regular quizzes. Department of Materials Science and Engineering 6

Reading assignments Questions may be asked to check if you have finished the assignment Extra credit for those who give right answer A student will be chosen randomly using dice Department of Materials Science and Engineering 7

Field Trips Three field trips are planned, depending on arrangements with metal processing companies. Field trips typically occur on Fridays and are required for on-campus students. Each field trip will result in 0.5% credit for participants See the class website for the dress code for field trips. Department of Materials Science and Engineering 8

Quizzes for Online students Quizzes may be given. Submission by email to ytzhu@ncsu.edu within 5 days. Correct answers will be given credits. https://www.youtube.com/watch?v=VE_4zHNcieM Samurai Sword (47min) http://www.youtube.com/watch?v=Ea_7Rnd8BTM Steelmaking (10 min) Department of Materials Science and Engineering 9
