Research Progress of Fusion Welding Techniques for TiNi Alloy to Steel

This review aimed to provide a comprehensive overview of the recent progress in fusion welding steel and heterogeneous metals introduce current research application. Amongst numerous metals, TiNi shape memory alloys have been most heavily investigated for producing excellent joints. However, base materials on both sides traditional must melt large melting point difference between two seriously affects weld formation. The metal compounds formed by also hinder improvement mechanical properties joint. focused fundamental understanding microstructural characteristics, processing property relationships joining primary problem finding intermediate with enhanced plasticity toughness improve formation Welding light high specific strength has wide range applications aerospace industry, it is committed reducing quality flight equipment.
