非均匀介质中马氏体晶体形成的波动模型
Wave model of forming of the martensite crystal in the heterogeneity medium
摘要:
在目前的工作中,考虑到晶体生长控制的波动模型,研究了介质的不均匀性对形成马氏体晶体形状的影响。在考虑非均匀性的基础上,提出了波的空间有效衰减。异质性的描述有三种不同的方式:指数,二次和逆二次。结果表明,根据介质的不均匀性,可以实现各种马氏体晶体的轮廓,同时考虑其对接的形状。特别是板状和楔形晶体形状是可行的。
英文摘要:
In the current work considering the wave model of the crystal growth control, an influence of heterogeneity of the medium on the forming martensite crystal s profile was examined. The considering of the heterogeneity is provided with the help of putting into operations the space-depending effective attenuation of the waves. The description of the heterogeneity was fulfilled in three different ways: exponential, quadratic and inverse-quadratic. It was shown, that dependently of the heterogeneity of the medium various martensite crystal s profile can be implemented, considering the shape of its butts as well. In particular the plate-like and the wedge-like of the crystal shapes are feasible.
