Abstract

Integration of two metallurgically distinct materials (bimetallic) is an inevitable advancement in the automotive and marine field. In this context, this study investigates the fabrication, characterization, and properties of solid–liquid compound cast aluminum alloy AA5052 and ferrous alloy (mild steel and galvanized iron) based bimetallic materials. Microstructural evolution, microhardness, and tensile strength of the developed bimetallic material are investigated. The results show that the formation of cracks at the interface in AA5052/Mild Steel caused the joint failure in the course of preliminary testing. In AA5052/Galvanized Iron, the growth of intermetallics at the oxide-free steel surface results in a shear strength of 19.9 MPa. XRD analysis attests to the presence of brittle intermetallics and Al bond at the interface of AA5052/Galvanized Iron bimetallic material, which in turn confirms the development of a metallurgical.

铝合金固液复合铸件的冶金学特征和力学性能：钢双金属材料

摘要

两种冶金学上不同的材料（双金属）的集成是汽车和海洋领域不可避免的进步。在此背景下，本研究调查了固液复合铸造铝合金 AA5052 和铁合金（低碳钢和镀锌铁）基双金属材料的制造、表征和性能。研究了开发的双金属材料的显微组织演变、显微硬度和拉伸强度。结果表明，在初步测试过程中，AA5052/低碳钢界面处裂纹的形成导致了接头失效。在 AA5052/Galvanized Iron 中，无氧化物钢表面金属间化合物的生长导致剪切强度为 19.9 MPa。
