G0410502 軟鋼の摩擦攪拌接合 : 適正接合条件([G041-05]機械材料・材料加工部門一般セッション(5),機械材料・材料加工部門)
詳細
A newly developed Ni base dual two-phase intermetallic alloy that has greater high-temperature strength and hardness than many conventional super alloys has been applied to FSW tools used to join mild steel plates with 1.0mm thickness. Appropriate joining conditions are evaluated by appearance of welded lines and tensile properties. The results show that the higher the tool revolution, the wider the appropriate ranges of joining speed. Furthermore, within the range of the experimental conditions, the slower the joining speed, the higher the tensile strength of the joints.
