本规范以固定的标记号B597公布,标记号后面的数字说明原来采用的年限或有更改情况下的最新更改年限。括弧中数字表示最近重新批准年限。 1. 范围 1.1 本推荐工艺旨在帮助制定适当的铝合金热处理工艺以保证获得良好的物理和机械性能。 1.2 对不同品种、尺寸和生产方法的制品所规定的时间和温度都是典型的,并且对特定的制品来说不一定是最佳的热处理规范。因此,并不意味用本推荐工艺来代替具体的生产工艺或程序。 This specification is published under the fixed reference number B597. The numbers following the reference numbers indicate the old years of service or the latest life of the change where the changes were made. The numbers in parentheses indicate the most recent re-approval period. 1. Scope 1.1 This recommended process is intended to assist in the development of suitable heat treatment processes for aluminum alloys to ensure good physical and mechanical properties. 1.2 The time and temperature specified for products of different varieties, sizes and methods of production are typical and may not be the optimal heat treatment specification for a particular product. Therefore, this does not mean that the recommended process to replace the specific production process or program.
