| Abstract: | The effects of type and content of alloying elements on the microstructure and mechanical properties of T/P91steel weld were studied through developing T/P91 electrode.The results show that the molybdenum element can decrease the phase transformation point of weld on the condition of having the similar content with other alloying elements.The molybdenum content in the deposited metal should be selected according to the upper limit of the criterion. |
