【摘要】 本文介绍了市售北京产ZnS粉,经真空热压烧结制备的HP-ZnS扫描电镜微组织形貌、透射电镜观察的显微组织、孪晶形貌、衍射图形以及对其电子衍射花样的标定,并以此证明孪生机制在热压烧结变形过程中占主导地位,但不是唯一的机制。更多还原

【Abstract】 Microstructure and morphology of HP-ZnS were observed by SEM and TEM respectively.The diffraction geometry for twinned structures was obtained,and the indices of the diffraction spots due to the twin in terms of matrix reciprocal lattice are deduced.At last mechanisms of plastic deformation during hotpressing were discussed bridfly.更多还原
