been reported that Sr effectively modifies eutectic Si by twin plane re-entrant edge (TPRE) mechanism in which the growth of eutectic Si occurs by twinning in {111} planes during solidification [39]. The external angle at re-entrant edges favours the nucleation and growth of Si in <112> direction. When Sr is added, it is adsorbed at the re-entrant edges and hinders the growth in <112>......

]. MA an LI [24] proposed that the small addition of rare earth (RE) elements including Sc could display positive effect on the strength of Al-Cu-Li alloys with low Cu/Li ratio, in which the δ’ (Al3Li...° was applied to re-indexing the data points, and two kinds of boundaries were defined. Low-angle boundary (LAB) was defined at a misorientation (θ) in the range of 2°-10° (2°<θ<10°), while high......

[3].为了改善传统工艺合金的短板,追求更优的综合力学性能,一些新的热处理手段如回归再时效(Reversion and re-aging)[4]和断续时效(Interrupted aging)[5]等也被提出.但是,受限于工艺条件或可适用性,上述新型热处理方法在工业实际生产中仍存在诸多问题. 近些年来,铝合金中的团簇强韧化研究引起了学界强烈的兴趣.溶质原子团簇,即溶质原子在基体中形成的纳米/亚纳米级... of Nonferrous Metals Society of China, 2016, 26(6): 1447-1471.
