摘要：
The crystallization kinetics of Ni-Mn alloy thin films is investigated by molecular dynamic simulation. The results show all curves have a single exothermic peak representing crystallization, and the isothermal peaks are significantly shifted to higher temperatures with increasing heating rate. When heating rate is 5??10(10) K/s, the crystallization temperatures is found at 715 K. Moreover, we find the crystallization behavior is a two-dimensional grown. Meanwhile, the Radial Distribution Function curves show crystallizing degree at different temperatures and the temperature is 600 K has a crystallization volume fraction is 28%. This work reveals the mechanism of the nucleation and growth in crystallization process.
