研究了焊接对冷轧态薄板Fel9Mn5.5Si8.5Cr5Ni(0.1Ti)合金性能和组织的影响.研究发现,合金具有良好的焊接性能,焊后试样具有与母材相近的抗拉强度,添加焊丝和未添加焊丝试样的抗拉强度分剐达到母材的97%和94%;同时焊后试样具有较好的延伸率,添加焊丝和未添加焊丝试样延伸率分别达到22.7%和19.8%.经过800℃退火30min处理后试样形状记忆效应最好,母材达到最大值85%,添加焊丝和未添加焊丝试样分别达到77%和80%.组织分析表明,添加焊丝试样溶合区较宽,未添加焊丝试样溶合区较窄,但两种工艺的接头均未发生晶粒异常长大,且未发生较大的元素偏析,因此焊后试样表现为韧性断裂.
