Lab IV: Heat Treatment

Handout         Lab Report Format         Microstructure Pictures          Grading Criteria



Microstructure Pictures

Click HERE for microstructure pictures taken of steel samples from a previous quarter that were subjected to the same heat treatments as your samples - use them in your report to talk about the microstructure of steel and how it changes with various heat treatments - Below, there are pictures from Callister included of all the materials - use them in your report as well - compare the Callister steel pictures to our experimental pictures, being careful of differences in magnification
