镁合金加工技术的发展趋势与开发应用前景

镁及其合金密度小,仅为铝的64％,钢的25％,是目前密度最轻的金属结构材料之一。由于它具有一系列的优越特性,近年来倍受汽车制造、航空航天、通讯、光仪、印制设备、电子计算机制造等工业部门的青睐,被誉为21世纪的金属。本文较详细地论述了镁及镁合金的特性、工艺特点与用途;镁工业的发展历史与现状;镁合金加工技术的发展水平和趋势;以及镁合金的开发应用领域和前景等。

Development Tendency of Mg - alloy Processing Technigue and Applied Prospedts

The density of magnesium and its alloys is yelatively low,only accounts for 64% of aluminum density and 25% of steel density,and it is one of the lightest structural metallic materials.Recently,owing to a series of superior properties of magnesium and its alloys,they are favorited by many industrial sectors such as automobile manufacture,aviation and spaceflight,communication,optical instrument,printing equipment,electronic computer manufacture etc.,and are reputed as the "21 century metals".In this paper,author discussed the properties of magnesium and its alloys,technological characteristics and use of magnesium and mg-alloys,the development history and present situation of magnesium industry and the developmental level and tendency of Mg-alloys processing technique,as well as application range and prospects of Mg-alloys,etc.,in more detail.
