MECHANICAL PROPERTIES OF HOT PRESSED ZINC SULPHIDEDIAMOND COMPOSITES

ZnS-Diatnond cotnPOsites (ZnS/D) were fabricated by hot pressing to obtain a ZnS ithered transparent materials with incmeed toughness. The relations of the mechanical properties and the diomond contents were investigated. It was determined that,when the content of diamond is in the mnge hem 1% to 10%, the toughness of the composite fits the equation KIC = cexp(a+bx). The constants c, a, and b determined experimentally are 10-6, d.47 and 9.70 respectively. 下载全文
