日本三菱金属公司应用烧结锻造技术,以急冷凝固铝合金粉末作为原料,开发了成本低、能制造形状复杂件的新方法。用这种方法制造产品比用普通的熔化法制造的产品强度和耐磨性都优越,而普通的粉末挤压法由于成本高,影响了推广应用。这种所谓粉末锻造法的关键是,将初步成型的件用模具直接成型为形状复杂的最终产品。其成本 Japan’s Mitsubishi metal company Sintering forging technology to rapidly solidified aluminum alloy powder as raw materials, the development of low cost, can create a new method of complex shape parts. Products made by this method have superior strength and abrasion resistance than those produced by the ordinary melting method. However, ordinary powder extrusion method has an impact on popularization and application because of its high cost. The key to this so-called powder forging method is to mold the preliminarily formed part into a complexly shaped final product directly using a mold. Its cost
