本文介绍两种异种钢焊接接头高温断裂性能试验方法。其中三点弯曲热疲劳试验是利用材料力学简支梁原理设计而成。直流电位法紧凑拉伸试验,是目前国内测试材料高温断裂韧性的一种新颖试验力法.
This article describes two kinds of dissimilar steel welded joints high temperature fracture properties of test methods. Among them, the three-point bending thermal fatigue test is designed by using the principle of simply supported beam mechanics. DC potential method compact tensile test, is currently a domestic test material high temperature fracture toughness of a novel test force method.
