Modeling of static coarsening of two-phase titanium alloy in the α+β two-phase region at different temperature by a cellular automata method被引量:1
《Chinese Science Bulletin》2013年第24期3023-3032,共10页WU Chuan YANG He LI HongWei 
supported by the National Natural Science Foundation of China (50935007, 51175428);the National Basic Research Program of China (2010CB731701);the Foundation for Fundamental Research of Northwestern Polytechnical University in China (NPU-FFR-JC20100229);the Center for Foreign Talent Introduction and Academic Exchange for Advanced Materials and Forming Technology Discipline Project (B08040)
A cellular automata (CA) method was employed to model static coarsening controlled by diffusion along grain boundaries at 1173K and through the bulk at 1213 and 1243K for a two-phase titanium alloy. In the CA model, t...

国家"973"子课题(No.2006CB202601)
本文采用等离子体增强化学气相沉积(PECVD)技术,在普通玻璃上制备了本征和掺磷的氢化微晶硅(μc-Si∶H)薄膜。利用Raman散射谱,计算了表征其薄膜微结构的晶化率(Xc)和平均晶粒尺寸(d)。结果表明随着磷烷(PH3)浓度的增加,其Xc和d均呈现...
