As a result, some ideas about the fabrication are put forward.The EPMA experiment results show that the main element such as W, Mo, Ti, Ni, Cu, Fe element are changed gradually in W-Mo and W-Mo-Ti FGM. In the layer rich in W, the grain are intervained and are mixed mechanismly. The same is to the layer rich in Mo and W-Mo. These grain felt up by some sinter. In Mo-Ti layer rich in Mo, the grains are also mixed mechanismly. Ni, Cu, Fe element assembled at interface. Ni melt by Cu plays an vital role in sinter effect. The microstructure characteristics result show that the compactness of W-Mo and W-Mo-Ti FGM is good.
电子探针实验结果表明W-Mo系、W-Mo-Ti系梯度功能材料中主要元素W、Mo、Ti、Ni、Fe、Cu分布整体上具有梯度变化规律,发现富W区、富Mo区、W-Mo混合区中颗粒交错分布,基本上以机械混合的形式存在,颗粒之间主要靠烧结剂的粘结作用实现致密化;以Mo为主要组分的Mo-Ti混合区,也是以机械混合的形式存在;Cu溶解于Ni形成固溶体更好地起到活化烧结能力,Ni、Cu、Fe在宏观层间界面富集,有利于烧结致密化。

Reliability evaluation of existing structures is shown from the angle of artificial neural network. The influencing factors and deformation characteristics of buildings above goafs are summarized based on the code of coal pillar design and pressed coal mining for buildings, water-bodies, railroads and main mine roadway. The model of neural network is build to solve the problems about complex influencing factors and long evaluating time of building evaluation. BP network model compared with traditional way has strong practicability and extension value.
