在热力学平衡的基础上,利用描述闪速熔炼中微量元素行为的数学模型,结合闪速熔炼整体平衡计算结果,对As,Sb,Bi在铜闪速熔炼中的行为进行了计算机模拟.计算结果与文献结果及工业观测数据吻合较好。同时,模拟计算了冰铜品位、氧气浓度、温度及精矿中微量元素含量等因素对微量元素行为的影响.

Plasma immersion ion implantation (PIII), unrestricted by sight-light process, is considered a proper method for inner surface strengthening. Two-dimensional simulation oj inner surface PIII process of cylindrical bores were carried out in this paper using cold plasma fluid model, and influence of...

Computer simulation of grain boundaries(GB) was carried out in Fe and ordered alloys NiAl and FeAl with B2 superlattice. In this work symmetrical tilt grain boundaries =5[100](012) and = 5[100](013) are studied. The atomic interaction has been described by Morse empirical central- force potential...
