摘 要：在钨尾矿微晶玻璃基体中加入25%(体积分数)的SiCW，可显著提高其断裂韧性和抗弯强度。观察了复合材料的形状记忆效应(SME)。通过微观分析，讨论了SiC晶须增韧补强的原因。
Abstract: Substantial improvements in fracture toughness(KIC) and bending strength(σbb) were obtained by incorporating 25%(volume fraction) of SiCW into tungsten tallings glass-ceramics matrix. The shape memory effect of the composite has been observed. The causes of SiC whisker toughening and reinforcing were discussed through microscopic analysis.
