Cyclic fracture toughness of metals and alloys - Part 2: effect of operation and processing factors

摘要

We explore into the effect of temperature, loading cycle asymmetry, the dimensions of specimens, plastic pre-strain, and damage to a material in the process of low-cyclic loading on the value of cyclic fracture toughness of heat-resistant, high-strength chrome-molyhdenum and other kind of steels. We have analyzed an extent of this effect depending on different factor varied during the investigation.
