    摘要:

    研究超聲處理對AZ80鎂合金微觀結(jié)構(gòu)演化及力學(xué)性能的影響。 研究表明，經(jīng)超聲處理后，初生α-Mg相由粗大的樹枝晶變?yōu)榧?xì)小的球狀等軸晶，且β-Mg17Al12相明顯細(xì)化，由連續(xù)網(wǎng)狀分布變成不連續(xù)分布。此外，合金經(jīng)超聲處理后，力學(xué)性能得到明顯提高，屈服強(qiáng)度、抗拉強(qiáng)度和伸長率分別由87MPa, 118MPa and 2.1% 提高到107MPa、170MPa 和 5.4%。

    Abstract:

    Ultrasonic effects on microstructure evolution and mechanical properties of AZ80 alloy were investigated. The results indicated that with the application of ultrasonic melt treatment, the primary α-Mg phases were transformed from coarse dendrites to nearly fine equiaxed grains, and the β-Mg17Al12 phases at α-Mg boundaries were refined and modified into discontinuous. Besides, the tensile properties of AZ80 alloy were apparently improved after ultrasonic melt treatment, in which the 0.2% tensile yield strength, ultimate tensile strength and elongation were improved from 87MPa, 118MPa and 2.1% to 107MPa, 170MPa and 5.4%, respectively.
