摘要: 为获得高性能干气压缩机用印刷电路板换热器,以不锈钢材料316L扩散焊接头为研究对象,在工作状态下对其不同扩散焊工艺下的力学性能进行了研究。结果证实:接头强度和韧性随焊接温度升高而增大,温度高于1 060 ℃时,强度变化较小;接头屈服强度和韧性均随焊接压力升高而升高,焊接压力大于10 MPa时,接头力学性能变化较小;随着保温时间延长,强度变化较小,韧性增加。综合考虑后,将工艺优化为扩散焊温度1 060~1 120 ℃、焊接压力10~13 MPa、保温时间60 min。

Abstract: In order to obtain high performance of the printed circuit plate heat exchanger for dry gas compressor, the mechanical properties of the stainless steel material 316L diffusion welded joints are investigated under different diffusion welding processes in working condition. The results confirm that the joint strength and toughness increase with the increase in welding temperature; when the welding temperature is higher than 1,060 ℃, the welding strength variation tendency is small; the joint yield strength and toughness increase with the increase in welding pressure; when the welding pressure is greater than 10 MPa, the joint mechanical properties change is small; with the extension of holding time, the strength changes slightly while the toughness increases. After comprehensive consideration, the process is optimized as follows: the diffusion welding temperature is 1,060~1,120 ℃, the welding pressure is 10~13 MPa, and the holding time is 60 min.
