Abstract

The thermal fatigue resistance of materials has been evaluated in a series of investigations using the fluidized bed method of thermal cycling. The factors that influence thermal cracking were studied for many materials and definite patterns of behavior observed. Particular attention was paid to H13 tool steel and an 18Ni maraging alloy as these represent materials with distinctly different mechanisms of heat treatment response.

Keywords:
