金属延展性

结果表明：在纯碳化硅材料中分别加入硅、铝粉之后，由于金属的延展性，在成型过程中有利的填充了碳化硅颗粒间的空隙，使得干坯更加致密。

The results show that : the specimens with metal silicon or aluminum powder become denser because the plastic metal powder contributes to filling the space .

Metallic coatings & Methods of measurement of ductility

这种金属易加工，延展性也好。

This metal is workable and ductile .

主要结论如下：（1）纳米晶金属Cu膜的延展性随着Cu膜厚度增大而下降。

The main results are summarized as follows : ( 1 ) The ductility of nanocrystalline Cu films decreased with increasing the film thickness .

由于大多数金属具有韧性和延展性，所以可以压成薄板和细丝。

As most metals are malleable and ductile they can be beaten into plates and drawn into wire .

普通非金属趋向于少延展性、无导电性，而且传热性能不好。

The common nonmetals tend to be less ductile , have no electrical conductivity , and have poor heat conductivity .
