Observing and analyzing of TEM show that 7090/SiCp precipitate G. P. area andη′phase with single aging, intensified effect is in best condition. the strength decrease obviously with double aging because precipitated phases become coarse and precipitateηphase when temperature increase.
TEM观察及分析结果表明,7090/SiCp复合材料经单级时效处理后的组织为G.P.区和η′相,强化效果最佳。 经双级时效处理时,由于温度升高,使析出相粗化并析出了η相,强度明显下降。
