摘要本研究的目的是发展一种锻造连接技术，在该技术中，铝合金和钢坯在一次冷锻过程中形成并彼此连接。获得了金属间良好结合的反挤压结果。为了验证其可靠性，采用微拉伸试验测量了粘接界面的粘接强度。在测试中，通过使用线切割机在接合边界处切割微拉伸测试样本。将试样在边界处切开，用扫描电子显微镜观察断裂表面。在观察过程中还测量了来自试样另一侧的粘附金属的表面积比。
Abstract The aim of this study is the development of a forge bonding technology in which Al alloy and steel billet are formed and bonded to each other in one cold forging process. A result of the good bond between the metals in backward extrusion is acquired now. The bonding strength on the bonding boundary was measured by microtensile test for the purpose of confirmation of its reliability. In the test, microtensile test specimens were cut off at the bonding boundary by using a wire cutting machine. The specimens were split on the boundary and the fractured surfaces were observed with a scanning electron microscope. Surface area ratio of adhesion metal which comes from the other side of specimen also was measured in the observation.
