The precipitation sequence in instable region is as follows : supersaturated solid solution congruent ordering spinodal decomposition stoicheometric phase it is found for the first time that with the increase of compositions , congruent ordering is enhanced , incubation period is shortened , spinodal decomposition is decreased , and volume fraction of ordered phase is increased
失稳区合金沉淀序列为：过饱和固溶体( ? )非化学计量比有序相( ? )化学计量比相等成分有序化也需要孕育期，首次发现随初始浓度的增加，孕育期缩短，等成分有序化速度加快，而失稳分解的速度相对减慢，有序相体积分数增加。
