The results show that the strict coupled growth between primary and peritectic phases only takes place at the temperature higher than peritectic phase transformation temperature in steady state. 研究结果表明:在定向凝固条件下,包晶系两相严格的共生生长只有在进入稳态且温度高于包晶相变温度时才可能进行;
The experimental results showed that the peritectic reaction did exist in the phase diagram of zinc-aluminium binary alloy. The β phase is leading one in the eutectic transformation, and the eutectic colony grown is radialized. 试验结果表明:在Zn&Al二元合金相图中确有包晶反应,β相是共晶转变的领先相,共晶团呈辐射状生长。
Some basic material problems in preparing YBCO superconductor by directional solidification, including the peritectic transformation and peritectic reaction, the constitutional undercooling, a diffusion controlled growth model of YBCO, the interface effect and crystallography for directional solidification, were discussed in the present paper. 讨论了定向凝固法制备YBCO超导体涉及的包晶转变与包晶反应、成分过冷、扩散控制生长模型、界面效应及定向凝固YBCO生长晶体学等问题。
For Fe-Sn monotectic alloys, larger cooling rate makes the peritectic transformation generally taking place at elevated temperatures suppressed. 在Fe-Sn偏晶系合金中,大的冷却速率使较高温度下惯常发生的包晶转变被抑制。
The result shows that the shrinkage mass and shrinkage rate induced by peritectic phase transformation is decreased with the increase of manganese content. 结果表明,随着锰含量的增加,碳钢包晶相变的收缩量逐渐减少,收缩速度逐渐降低。
