为了减轻零件和结构的重量,提高机器的生产率和节约稀缺的材料,依靠在工业上采用模合金来扩大机器制造业的可能性,必然带来技术上的极大进步。在各种形式的运输工具上应用镁合金是最有前途的。为了用压力加工的方法有效地制造这些合金的零件和半制品,必须了解这些合金的机械和工艺的全部机械特性。由于镁合金具有极高的脆性,以前曾有过镁合金 In order to reduce the weight of parts and structures, improve machine productivity and save scarce materials, technological advances are inevitable, relying on the possibility of using die-cast alloys to expand the machinery manufacturing industry. Magnesium alloys are the most promising applications in all forms of transportation. In order to efficiently manufacture parts and semi-products of these alloys by means of press working, it is necessary to understand the overall mechanical properties of the machinery and the process of these alloys. Magnesium alloys have been used before because of their extremely high brittleness
