High manganese steels undergo a ductile to brittle transition at low temperature, which is accompanied by a change in the fracture mechanism from dimple fracture to intergranular fracture.
高锰奥氏体钢随温度降低其断裂机制由韧窝状断裂转变到晶界断裂。
The crack propagation rate of pipes is mainly dependent on FATT of Steels of pipes (fracture appearance transition temperature). And FATT can be measured by drop weighted tear tests.
管道裂纹的扩展速度主要取决于管道钢的转变温度FATT。FATT可由落锤撕裂试验测定。
