Abstract

Statistical design of experiments was employed to study the effect of austenitizing temperature, austempering temperature, and austempering time on the quasi-static and dynamic fracture toughness of austempered ductile iron of a standard composition. Regression equations were developed to determine the relative significance of the variables in affecting the quasi-static and dynamic fracture toughness of the austempered iron studied.

Keywords:
austempering temperature, austempering time, fracture toughness testing
