| Abstract: | The article analyses equal secondary phase configuration and its separation's thermodynamics conditions of metal space compound produced from two phase stainless steel and its weld as well as its heat affected zone and points out the separation of metal space compound phase among the weld and its heat affected zone of low alloy two phase stainless steel usually is lightly,only this problem among ultra two phase stainless steel of the high alloy is seriously. |
