    摘要:

    對(duì)變形AZ31鎂合金在連鑄過(guò)程中有、無(wú)施加電磁場(chǎng)和微鈣合金化進(jìn)行試驗(yàn)研究，并對(duì)鑄錠的表觀質(zhì)量、微觀組織和力學(xué)性能進(jìn)行對(duì)比分析。結(jié)果表明：微鈣合金化和電磁場(chǎng)復(fù)合作用能連續(xù)鑄造出表面光滑、無(wú)氧化夾雜和偏析瘤的高質(zhì)量鑄錠，合金的微觀組織得到改善，合金的晶粒在鑄錠內(nèi)外一致，析出相呈圓點(diǎn)狀或近圓點(diǎn)狀彌散分布于基體。微鈣合金化和電磁場(chǎng)復(fù)合作用對(duì)合金抗拉強(qiáng)度的提高近15%，對(duì)合金延伸率的改善更加有效，相對(duì)于普通連鑄的AZ31鎂合金，在微鈣合金化和電磁場(chǎng)復(fù)合作用下AZ31鎂合金的延伸率提高近90%

    Abstract:

    The continuous castings of wrought magnesium alloy AZ31 with or without the effects of electromagnetic field and Ca microalloying were investigated，and the appearances, microstructures and mechanical properties were compared. The results show that the ingots with the electromagnetic field casting (EMC) and Ca microalloying have smooth surface, and the defects, such as segregation, trapped oxide can be eliminated on the ingot surface. Through EMC and Ca microalloying, the microstructure is improved and the grain in the border and center of the ingot has a same size, the β-Mg17Al12 phases with the shape of dot and approximate dot distribute in the basal body uniformly. The yield strength and elongation increase by 15% and 90%, respectively, for the ingot with EMC and Ca microalloying compared to the ingot without EMC and Ca microalloying
