利用强磁场有可能在材料中形成大的整体过冷,可实现材料的整体凝固。
最后给出了采用深过冷快速凝固技术制备微晶软磁合金的研究内容。
综合本文实验研究结果表明,结晶时的过冷度才是导致石墨球状生长的主要因素。
研究了微量铌、钼、镍对过冷灰铸铁组织和力学性能的影响。
1·An explicit finite-difference method (FDM) was used to model and simulate the solidification of eutectic cast iron by combining heat transfer equations with undercooling nucleation and growth laws.
综合热传导方程与过冷形核、生长规律,用显式有限差分法模拟了共晶铸铁的凝固过程。
2·Low undercooling degree, the rate high back press. On the heating equipments with condensed water and the recovery system engineering, even show its ascendant function.
过冷度小,背压率高。在加热设备和凝结水回收系统工程上使用,更显其优越性能。
