简介：为稳固的氧化物的NiO/SDCcomposites和Ni/SDC金属陶瓷造成房间(SOFC)阳极应用程序从氧化镍(NiO)被准备，samaria做了由粉末冶金学的粉末处理的二氧化铈(SDC)。NiO/SDCcomposites和Ni/SDC金属陶瓷的物理、机械的性质，以及微观结构被调查。NiO/SDCcomposites和NiO内容的sintering温度在决定NiO/SDCcomposites的微观结构和性质起一个重要作用，这被显示出，接着，它影响Ni/SDC金属陶瓷的微观结构，电的传导性，和机械性质。Thepresent学习表明了那篇作文并且(进程参数必须适当地被选择优化微观结构，为稳固的氧化物的NiO/SDC材料的性质造成房间应用程序。

简介：Diamond/Cu-xCrcomposites被压力渗入过程制作。diamond/Cu-xCr的热传导性(x=0.1，0.5，0.8)composites在650W/mK上面，比diamond/Cucomposites的高。张力的力量从186～225MPa，并且结合的力量从400～525MPa。thermo物理的性质和接口结构上的Cr元素的影响被分析。当Cr3C2和Cr3C2的数量随Cu-xCr合金的Cr集中的增加增加了，中间的层被证实。当Cr集中直到0.5wt.%时，Cr3C2层的内容是不变的。当Cr3C2层的厚度变得更大，composites显示出更低的热传导性但是更高机械的性质。diamond/Cu-xCr的热扩大(CTE)的系数(x=0.1，0.5，0.8)composites在对Kerner模型的预言的好同意。
