和含碳量较高的合金不同，含碳量低的合金稍软一些，在锻造过程中，两种合金熔合在一起，就会形成极其漂亮的花纹。

Metal with low carbon level is soft unlike metal that contains much carbon. In forging the two kinds of metal are mixed forming the most beautiful pattern.

想象一种金属，它可以“记忆”其初始、冷锻造的形状，当受热或磁脉冲时会回复到该形状。

Imagine a metal that "remembers" its original, cold-forged shape, and can return to that shape when exposed to heat or a magnetic pulse.
