Purpose
In this experiment our goal was to investigate the effects of a bullet impacting different materials. We accomplished this by cross sectioning the material at the bullet impact site then looking at the microstructure.
Setup• Material Preparation: – Steel: (2 thin, 2 thick)• 1 of each thickness, heated to 900⁰C then furnace
cooled• 1 of each thickness, heated to 900⁰C then quenched to
room temp
