316L不锈钢搅拌摩擦焊与氩弧焊接接头组织性能比较
|
摘要
对316L不锈钢分别进行了搅拌摩擦焊接和钨极氩弧双面焊接,研究了不同焊接方法所得焊接接头组织性能的变化。结果表明:搅拌摩擦焊接过程中,由于焊缝金属受到了剧烈的机械搅拌和塑性变形促使母材粗大的晶粒破碎,组织晶粒明显细化;钨极氩弧焊接过程中,焊缝区域温度超过了焊件材料的熔点,整个焊接过程属于小熔池的凝固,焊缝呈现出典型的铸态组织。在焊接工艺参数选择合适的情况下,搅拌摩擦焊接接头的显微硬度与母材和钨极氩弧焊接接头相比显著提高。细晶强化作用对搅拌摩擦焊接接头显微硬度的提高起到了至关重要的作用。
316L stainless steels were welded by FSW and TIG( two surfaces). Variation of joints microstructure and properties by different welding methods was studied. The results show that the effect of severe mechanical stirring and intense plastic deformation create coarse grains crush in base metal and the grains is obviously refined during FSW. As for TIG,because the welding temperature exceeds the melting point of welded material itself,the whole welding is equivalent to the solidification of a small molten pool,and weld metal presents a typical cast microstructure. Under the welding process parameters right conditions,the microhardness of welding joint with FSW is obviously higher than that of base metal and ones with TIG. Fine grain strengthening plays an important role in the improvement of the welding joint microhardness with FSW.
