振动时效法被有些人称之为“奇迹”工艺,它确能消除大型铸件(或焊接件)的应力,这种工艺可以代替回火和时效处理.其优点很多:如不改变金属性质、节省时间、节约能源、设备简单、适宜于大型结构特别是厚薄不匀的大铸件等等.因此,它日益得到有关方面的重视,并正着手在进行研究和应用. Vibration-aging is what some people call the “miracle” process, and it can actually eliminate the stresses of large castings (or welds), a process that can replace tempering and aging treatments, and has many advantages: it saves time, without changing the nature of the metal , Saving energy, simple equipment, suitable for large structures, especially uneven thickness of large castings, etc. Therefore, it is getting more and more attention, and is now in the process of research and application.
