摘要
摘要 汽车行业一直在努力减轻汽车重量，以减少污染物气体排放。双金属部件等创新概念的使用已变得颇具吸引力，因为它可以提高部件的强度重量比。本研究探讨了双金属十字头的热锻工艺。在这一过程中，镁合金 AZ61 的圆柱形芯坯与铝合金 AA 6351 的空心圆柱体被包裹在一起，并在 400°C 的温度下进行锻造。目的是协调镁合金的低密度和铝合金的高耐腐蚀性。与此同时，还对这一过程进行了有限元分析。
Numerical and Experimental Analysis of the Forging of a Bimetallic Crosshead
Abstract The automobile sector has been making increasing efforts to reduce the weight of automobiles, aiming at mitigating pollutant gas emissions. The use of innovative concepts, such as bimetallic components, has become attractive because it makes it possible to increase the strength-to-weight ratio of the components. In this study, the hot forging of a bimetallic crosshead is investigated. In the process, a billet with a cylindrical core of the magnesium alloy AZ61 is enclosed with a hollow cylinder of the aluminum alloy AA 6351 and forged at 400°C. The objective is to reconcile the low density of Mg alloys with the high corrosion resistance of Al alloys. In parallel, a finite element analysis of the process was carried out.
