摘要
本文研究了双相不锈钢中晶粒大小与强度的关系以及晶粒大小对氢致开裂的影响,发现在双相不锈钢中,晶粒尺寸与强度之间仍然遵循Hall-Petch关系式,晶粒尺寸越大,双相不锈钢对氢致开裂的敏感性越大。
The relation between grain size and strength of the duplex stainlesssteels and the influence of grain size on the properties of hydrogen induced crack-ing in these steels have been investigated. The Hall-Petch relation between grainsize and strength of the duplex stainless steels is also followed. The susceptibilityto hydrogen induced cracking of the present steels increases with increasing grainsize.
