1·Once ductility is introduced, materials become weak.
而一旦把延展性引入进来，材料就变得脆弱了。
2·Metals are elements that generally have good electrical and thermal conductivity. Many metals have high strength, high stiffness, and have good ductility.
金属就是通常具有良好导电性和导热性的元素。许多金属具有高强度、高硬度以及良好的延展性。
3·A part surface can be infiltrated with a low melting point metal to increase density, strength, hardness, ductility and impact resistance.
零件表面能被低熔点金属渗透以增大密度、强度、硬度、延展性和抗冲击能力。
4·Causes the steel to produce the hot brittleness, reduces the steel the ductility and the toughness, when forging and rolling crack.
使钢产生热脆性，降低钢的延展性和韧性，在锻造和轧制时形成裂纹。
5·Tests used to assess the ductility and malleability of stainless steel subjected to bending.
测试不锈钢在弯曲状态下的延展性及可锻性。
