采用实验和分析相结合的方法，研究了不锈钢-半固态铝合金复合材料的界面强度和组织。采用半固态连接技术，成功地实现了不锈钢与半固态铝合金的连接。建立了铝合金界面剪切强度与固相分数的关系。用光学显微镜和扫描电镜研究了复合板的界面结构。结果表明，铝合金的最佳固相分数为30%，最大界面剪切强度为106.17MPa。由于铝合金固、液相扩散能力的不同，固、液相沿结合界面沿着与不锈钢结合。复合材料的断裂是塑性断裂和脆性断裂的复合断裂，在界面处形成了一种新型的非平衡扩散界面结构。
Interfacial strength and structure of stainless steel–semi-solid aluminum alloy clad metal are studied by means of the experimental and analytical methods. Using semi-solid joining technique, the bonding of stainless steel and semi-solid aluminum alloy is successfully realized. The relationship between interfacial shear strength with solid fraction of aluminum alloy is established. The interfacial structure of the bonding clad plate is studied by means of OM and SEM. It is shown that the best solid fraction of aluminum alloy is 30% and the maximum interfacial shear strength is 106.17 MPa. Solid phase and liquid phase are bonded with stainless steel by turns along the bonding interface, because of different diffusion ability of solid and liquid phase of aluminum alloy. There is a compound fracture combined plastic fracture and brittle fracture, and a new type of non-equilibrium diffusion interfacial structure is constructed in the interface.
