spheroidize

The results indicated that with solution time increasing, Mg_ ( 17) Al_ ( 12) phase was dissolved into the Mg matrix and Al_2Ca phase became thinner and shorter, then gradually broken and began to spheroidize;

结果表明：合金轧制后，随着固溶时间的增加，Mg17Al12相通过原子扩散弥散固溶到镁基体中；而Al2Ca相比较稳定，部分变细，逐渐断开并出现球化现象。

The addition of RE oxide not only could refine the microstructure, but also could purify the grain boundary and spheroidize the carbide, and all of these could contribute to improving the toughness of deposit.

稀土氧化物仅细化了组织，而且可以净化晶界，使碳化物球化，这些都为提高堆焊层的韧性做出了贡献。

Injection feeding technology was used to desulphurize and spheroidize ductile iron melt in industrial production. The screened feeding speed and Spheroidizing temperature of the melt were fixed in the experiments.

在工业上用喂线法对铁液进行球化脱硫处理，通过试验确定最佳喂线速度和合适的铁液处理温度，并对喂线法与冲入法进行了技术、经济的比较。
