本研究針對直徑為10mm的AISI 1045碳鋼與SUS 304不鏽鋼進行高週波感應加熱異種鋼材摩擦焊接實驗。另外亦使用DEFORM有限元素分析軟體，在不同加熱線圈種類(雙匝螺管型、三匝同心圓型、U型)及線圈偏移位置(0、1、2、3、4、5mm)下來進行焊接溫度的分析模擬，以找出較佳的線圈位置偏移量，以利實驗時獲得較佳的成品。針對壓接實驗後的產品進行剪斷試驗與硬度試驗等機械性質的評估。由剪斷試驗結果可以發現，焊接前試片的表面處理會影響焊接面的剪斷強度，且因為焊接面受到高溫與高壓的影響，焊接面的硬度會大幅度增加，並造成剪斷面的破壞方式為脆性破壞，在微觀結構方面，觀察到晶粒在焊接面附近會有明顯的細化區，且細化區會隨著焊接溫度的增高而變大。另外在接合面會有一層淺灰色的析出層，而此析出層會造成該區域的嚴重硬化。

In this study, Friction Welding experiment of Dissimilar metals of 10mm diameter AISI 1045 carbon steel and SUS 304 stainless steel by high frequency induction Heating was carried out .In addition a finite element analysis software DEFORM is used to analyze the welding temperature under various forming condition such as in different coil types of double-twisted solenoid、 triple-twisted concentric and U-type and coil offset position of 0、1、 2、 3、4、5 mm .A better coil position offset for a better finished product during the experiment. The mechanical properties are obtained using shear test and the hardness test were evaluated for the products after the crimping test. It is found from the shear test results that the surface treatment of the test piece before welding affects the shear strength of the welded interface, and because the welding interface is affected by high temperature and high pressure, the hardness of the welded surface will increase greatly. The failure mode is brittle failure. In terms of microstructure, it is observed that the grain will have a will fine grain zone is near the welding interface.The refine zone will become larger as the welding temperature increases. In addition, there is a layer of light gray precipitating on the joint interface, and this layer will cause severe hardening of the area.
