MSE 512 Powder Processing

Sem. 1. Class 3, cr. 3. (offered in alternate years). Prerequisite: MSE 230 or consent of instructor

MSE 512 is an elective course.

Weekly Schedule: Three 50-minute lectures.

Relation of Course to Program Outcomes
1. an ability to apply knowledge of mathematics, science, and engineering to problems in materials engineering.
5. an ability to identify, formulate, and solve engineering problems, particularly in the context of materials selection and design.
7. an ability to exhibit effective oral and written communication skills.
1.  To understand methods for the production of powders and particulate matter.
2.  To understand the methods used to characterize powders.
3.  To understand the processes controlling particle interraction.
4.  To understand approaches to powder consolidation.
5.  To understand densification and microstructural development in powders compacts.
Course Objectives
Upon completion of this course the student is expected to:
  • describe a powder fabrication process from starting reagent to finished powder. interpret a particle size distribution and estimate mean particle size and specific surface area from the data
  • review an ASTM standard for particulate materials characterization.
  • describe the role of van der Waals interactions in determining structure on the colloidal and macroscopic length scales.
  • differentiate between processing routes more favorable for processing bulk materials versus routes geared towards processing thin films.
  • describe when it is appropriate to process dry powders versus processing powders suspended in a liquid medium.
  • calculate the packing density of bimodal particle size distributions and describe the difference between calculated values and what one might expect to observe in experimental measurements.
  • describe the effects of particle agglomeration on interparticle forces and the packing density of powder compacts.
  • calculate the particle size at which gravitational segregation becomes significant during aqueous colloidal processing.
  • describe how segregation effects may be minimized during aqueous colloidal processing, and any advantages and disadvantages associated with the modified process.
  • describe the effects of interparticle forces on powder compact homogeneity and subsequent effects on compact densification.
  • describe the effects of furnace atmosphere on the density, the specific surface area, and the microstructure of a powder compact.
