Specific Course Information

  1. Catalog Description: An introduction to the relationships between the processing of materials and their properties. Heat treating, forming, casting, consolidation, and other more material-specific manufacturing processes. Elucidation of the role of phenomena such as heat flow, mass diffusion, nucleation, interfacial tension, elastic and plastic deformation, precipitation, recrystallization and grain growth.
  2. Prerequisites: MSE 26000 or consent of instructor.
  3. Course Status: MSE 33000 is a required course.

Specific Goals for the Course

1. All Students

A. Recognize the effect of processing variables (e.g., temperature, composition, size) on materials characteristics. Examples:

  • Effect of curvature on vapor pressure.
  • Effect of particle size on surface area/energy.
  • Effect of segregation coefficient on solute segregation and dendritic growth.
  • Effect of the amount of cold work on the recrystallization temperature.

B. Perform simple calculations to quantify material properties and microstructural characteristics. Examples:

  • Surface energy density of a powder.
  • The effect of shape factor on activation energy barrier for nucleation.
  • Calculate a segregation coefficient from a phase diagram.

C. Ability to revisit and apply concepts used in MSE 230. Examples:

  • Reading phase diagrams and recognizing invariant reactions.
  • Apply Fick’s first law to predict concentration profile of diffusing species.
  • Recognize the effects of cold-work and heat treatment on material properties.

D. Effective written communication in a Patent Review or other writing assignment.

2. Most Students

A. Make appropriate qualitative judgments regarding the effects of materials characteristics and/or processing variables on microstructure, composition and properties. Examples:

  • Relationship between dendritic growth and solidification porosity.
  • Effect of interfacial energy on particle/pore shape.
  • Effect of undercooling on homogeneous nucleation.
  • Composition profile of a bar undergoing directional solidification.
  • Effect of ductility on packing density of powders.
  • Predict the effect of heat-treating parameters on microstructure.

B. Making appropriate connections between equations/calculations and physical phenomena. Examples:

  • Effect of sample size and heat transfer on the hardenability of steel.
  • Effect of invariant reactions on cooling curves.
  • Relative magnitude of gravitational and interparticle forces.
  • Effect of compaction pressure on powder packing density.

C. Perform “non-simple” calculations. Examples:

  • Quantifying composition of a directionally solidified bar of material.
  • Effect of pressure and thermal contraction on the shrinkage of injection molded polymers.
  • Effect of latent heat on cooling time during solidification.

3. Some Students

A. Ability to explain the fundamental basis for materials phenomena. Examples:

  • Effect of aliovalent dopants on cation and anion diffusion.
  • Explain the temperature dependence of driving forces for various materials phenomena.
