Tool Steel Pacification and Heat-Treatment of Wear Resistance Steel and D3 Steel

This research “theoretical and experimental” in Effect of Heat-treatment “hardening temperature, tempering temperature, and cooling rate“ in the Mechanical property “Hardness”, and Microstructure transformation on Tool

Steel, all type of wear resistance steel, and specially D3

steel.

The research study heat-treatment for two pieces of D3 die steel

"Working at cone pulleys for nail manufacture" to modify there

mechanical properties.

The classification its type, properties and set on condition effect on it was discussed.

Two set of experiments were done one to determine the effect of austenitization temperature and tempering temperature on the mechanical properties "hardness" and another "the basic one" to discuses improving its mechanical properties from view of microstructure transformations "type, amount, and properties" for each heat-treatment stage.

This study was APPROVED as my BS graduate project from Metallurgy Engineering Collage, Cairo University 2001, and published after addition in experimental review at 2018.
