Short-Time Creep Behavior of Heat-Treated 4340 Steel under Uniaxial Tensile and 1:2 Tension-Tension Biaxial Loading

摘要

The report presents the results of an experimental investigation to determine the short-time creep characteristics of heat-treated 4340 steel after rapid heating under load for uniaxial tensile loading and 1:2 tension-tension biaxial loading. Tests were conducted at three different stress levels at 700 and 1000F. The test results and their analysis with regard to previously established creep analysis procedures and classical plasticity theory are presented. (Author)
