摘要

本文综述了铝合金锻件的特点、材料性能及典型应用。介绍了世界上使用最广泛的合金命名系统,并讨论了五大类别,即平轧产品;棒、棒、线;管状产品;形状;和锻件。本文还讨论了定义铝合金抗断裂性能的三个常用指标:缺口韧性、抗撕裂韧性和平面应变断裂韧性。它还描述了这些合金的三种腐蚀攻击:一般或大气表面腐蚀,应力腐蚀开裂和剥落攻击。

Properties and Applications of Wrought Aluminum Alloys
This article summarizes the characteristics, material properties, and typical applications of aluminum alloy wrought products. It describes the most widely used worldwide alloy designation system and discusses five major categories, namely flat-rolled products; rod, bar, and wire; tubular products; shapes; and forgings. The article also discusses three widely used indexes to define the fracture resistance of aluminum alloys: notch toughness, tear resistance, and plane-strain fracture toughness. It also describes three types of corrosion attack of these alloys: general or atmospheric surface corrosion, stress-corrosion cracking, and exfoliation attack.
