Steel Tempering
This research investigates tempering heat treatments for 4140 steel. The project has grown out of a collaboration with the Center for Heat Treat Excellence at Worcester Polytechnic Institute. We are exploring the effects of heating rate and tempering time on microstructural changes and related mechanical properties. Thermal processing is carried out using conventional lab furnaces and a Gleeble 3500.

Cast Microstructures
This project compares the secondary dendrite arm spacing (SDAS) to the cooling rate and alloy composition to build constitutive equations that describe the processing-structure relationships for several copper alloys.
