形形色色的特殊金属材料金属学家通过大量研究和反复试验,制造了—些具有优异性能和特殊用途的金属。这是金属中的一簇奇葩。超塑性金属超塑性金属就是把坚硬的金属变为软如面团可任人搓圆压扁的金属。最近问世的锌基铝合金就是其中的一种。当把它加热到摄氏250~度左右就具有超
A wide range of special metal materials Metals scientists through a large number of research and trial and error, made - with some excellent performance and special purpose metal. This is a wonderful bunch of metal. Superplastic metal superplastic metal is the hard metal into a soft dough can be Ren Ren round flattened metal. The recently introduced zinc-based aluminum alloy is one of them. When it is heated to 250 degrees Celsius to have super
