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.

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.

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.
