摘要：
The effects of brazing temperature on microstructure and mechanical properties of vacuum brazed joints of 316L stainless steel were studied. Choose three soldering temperature. After soldering, observed the microstructure, element distribution, microhardness and shear strength of welding clearance. The results show that the welding temperature for 940 degrees C, the brazing clearance organization mainly by Ni-Cr-P phase composition. Joint performance is poor, element can't get enough spread. P element does not spread easily, mainly in the brazing clearance; Cr element can spread along the grain boundary into mother material; the ability of spread of Ni elements is less than the Cr element. While welding temperature of 970 degrees C, the shear strength is the highest, and the comprehensive performance is the best.
