研究了固溶处理对S31803双相钢焊接接头力学性能的影响。结果表明:经固溶处理的焊缝,其硬度、抗冲击强度和抗拉强度都要比未固溶处理的焊缝高。
The effect of solution treatment on the mechanical properties of S31803 duplex welded joints was studied. The results show that the hardness, impact strength and tensile strength of the weld treated by solution treatment are higher than those of untreated weld.
