; (33) 式中:kBT(注:下标B为Buckling的首写字母,表示"屈曲";T为Thin的首写字母,表示"细长")是由修正正应力而引入的常数,取决于多孔体的制备工艺条件,因而集中了结构缺陷,孔隙具体形状和大小分布等因素的综合作用. 由于弹性模量E是材料的固有参量......
used in thin-walled components such as fuselage and lower wings [10]. The Al-Cu-Li alloys with the major solute elements of Cu and Li and minor solute additions of Mg and Ag show a complicated... generates the main strengthening T1 precipitate with the nominal composition of Al2CuLi, which forms thin platelets on {111} planes of the Al matrix. The T1 precipitate was initially thought to be hardly......
, the sample was thinned to a foil from ~50 to 80 μm, and then eletropolished at -30 °C in the solution of 33 vol.% HNO3 and 67 vol.% CH3OH. The thin foil was observed by the TEM (JEM 2100F) operated......
