在2219-T8铝合金搅拌摩擦焊(FSW)接头焊核区(NZ)发现了局部液化现象。采用热处理和热模拟2种方法对比分析了局部液化区组织的特点,采用显微硬度计和原位拉伸实验研究了局部液化对接头力学性能的影响。结果表明,局部液化是由NZ中的Al2Cu相与周围基体的共晶反应,即发生了组分液化所致。液化区为液相+α(Al)相的半固态组织,冷却时高熔点组元α(Al)相先析出,同时在搅拌挤压和材料流动的作用下发生固液分离,形成离异共晶。液化区的硬度低于NZ正常区域,是NZ微区试样断裂的起源,降低了NZ的抗拉强度和延伸率。不过,由于液化区域是局部的、极少量的存在于NZ中,其对接头拉伸性能的影响远小于整体均发生弱化的热机械影响(TMAZ)的影响。
