TaW12合金加工态电子束焊缝的力学性能研究王峰,王晖,梁静,蔡小梅,张小明,郑欣,李来平西北有色金属研究院摘 要:对3mm厚TaW12合金板材进行真空电子束对接焊,随后成功地将该板材冷轧减薄到2mm厚和1.5mm厚,表明TaW12合金电子束焊缝具有较好的冷加工性能.拉伸试验结果表明,单纯电子束焊接仅能使合金抗拉强度达到699.65~721 MPa,延伸率达到9.38%~13.15%,而1.5mm厚板材加工态焊缝的抗拉强度可达934 MPa,约为冷轧态1.5mm厚基材抗拉强度的93.8%~94.7%,延伸率达到8.0%~9.0%;所有被焊拉伸试样均沿焊缝中心处断裂.加工态电子束焊缝具有更高的强度和塑性,这是焊缝微观组织大大细化和冷轧制加工促进焊缝气孔闭合的结果.关键词:钽合金;TaW12......
