Ductility是什么？

Ductility是什么？

词义解释

Ductility（延展性）是物质在外力作用下变形的能力，它是识别物质变形了多少的能力量度标准。通俗的讲，当我们拉扯一个物体，例如金属丝时，它是否会被轻易地延展或断裂？如果金属丝可以被拉长而不会断裂，那么它就具有高延展性。

Ductility的重要性

在原材料工业、建筑工业、航空工业和制造商业等各个领域，Ductility都是一个非常重要的特性。例如，汽车工业需要使用高延展性材料来制造安全带和车身结构，因为高延展性材料能够更好地在碰撞和事故中吸收冲击和应力。飞机工业也需要使用高延展性的金属材料来制造飞机部件，可以更好地抵御高空飞行时的压力和震动，并防止出现裂纹和其他损坏。
