We report on interfacial characteristics and chemistry of bonded Mg-Fe interfaces welded using friction stir assisted scribe technique (FaST). Two pairs of dissimilar joints: (AZ31-DP590) and (Pure Mg-DP590) were studied to shed light on joining mechanisms responsible for bonding of “immiscible” pairs of Mg and Fe. We present first direct experimental evidence of presence of oxide layer, Al segregation by atom probe tomography and nano steel grains close to interface by transmission electron microscopy study.

Fe和Mg合金互溶的搅拌摩擦划线中的界面反应。

我们报告了使用摩擦搅拌辅助划线技术（FaST）焊接的粘结Mg-Fe界面的界面特性和化学性质。研究了两对异种接头：（AZ31-DP590）和（纯Mg-DP590），以阐明负责“互溶”的Mg和Fe对结合的结合机理。我们提供了第一个直接的实验证据，表明存在氧化物层，通过原子探针断层摄影术进行的铝偏析以及通过透射电子显微镜研究接近界面的纳米钢晶粒。
