energy for crystallization process is decreased after Sc addition, the incubation period constant is enlarged and the frequency factor is reduced. The synthetical influence of these two aspects makes the incubation period prolonged, supercooled tendency increased and therefore glass forming ability improved. Key words: Zr-based bulk amorphous alloy; glass forming ability; thermal stability......

that the nucleation incubation period of B2-FeAl ordered domains becomes longer with the increase of aging temperature,and it becomes shorter with the increase of Al content. The long-range order parameter of ordered... phase-field; B2-FeAl intermetallics compound; nucleation incubation period; long-range order parameter; ordered domain boundary......
J. Cent. South Univ. (2016) 23: 2935-2940 DOI: 10.1007/s11771-016-3357-9 Nonlinear chaotic characteristic in leaching process and prediction of leaching cycle period LIU Chao(刘超), WU Ai-xiang(吴爱祥... demonstrated. According to the laws, a prediction model of leaching cycle period has been established to provide a theoretical foundation for solution mining. Key words: leaching system; phase space......
Ni75Al5Cr20合金中预析出相的微观相场模拟唐洪奎1,王永欣1,陈铮1,董卫平1,刘啸峰1,王永彪1(1.陕西省西安市西北工业大学凝固技术国家重点实验室)摘 要:采用微观相场法模拟了Ni75Al5Cr20合金的时效过程,研究了Cr和Al原子在无序fcc固溶体(001)和(002)面上序参数变化与相结构演化之间的关系.结果表明,合金时效序列为:无序基体→L10(M=1)预析出相→DO22相.在时效的最初阶段,原子只在面内跃迁,发生面内原子有序化,形成L10(M=1)结构;此后,原子在面间跃迁,原子在(001......
Replenishment policy and inventory optimization for supply-hub with liability period considerationLI Guo(李果) 1, HUANG Kun(黄焜)2, YAO Qi(姚琦)3, MA Shi-hua(马士华)2(1. School of Management and Economics.... The result shows that liability period decides the share of the inventory cost between two sides in supply chain. With the increase of liability period, the service level has been quickly reduced even......
Phenomena in late period of seeded precipitation of sodium aluminate solution LI Xiao-bin(李小斌), FENG Gang-tao(冯港涛), ZHOU Qiu-sheng(周秋生), PENG Zhi-hong(彭志宏), LIU Gui-hua(刘桂华) School... ratio(αk>2.4), corresponding to the late period of seeded precipitation, the influence of different types of seed on precipitation ratio was explained with respect to solution structure......
Optimal allocation of random access period for wireless body area networkJin hyuk KIM, Chang ki HONG, Sang bang CHOI(Department of Electronic Engineering, Inha University, Incheon 402-751, Korea.... In this work, we analyze the efficiency of simple slotted ALOHA scheme, and then propose a novel allocation scheme that controls the random access period and packet transmission probability to optimize......
