本规范涵盖模锻和锻坯形式的铝合金。这些锻件通常用于要求中等三轴强度、低密度、高模量和良好抗应力腐蚀开裂组合的应用，但使用不限于此类应用。这种氧化物和碳化物弥散强化铝合金不可热处理。为了获得所需的性能，需要控制锻造参数。

This specification covers an aluminum alloy in the form of die forgings and forging stock. These forgings have been used typically for applications requiring moderate triaxial strength, low density, high modulus, and good resistance to a combination of stress-corrosion cracking, but usage is not limited to such applications. This oxide and carbide dispersion-strengthened aluminum alloy is not heat-treatable. Control of forging parameters is required to achieve the required properties.
