通过热处理对云母微晶玻璃预制裂纹的愈合进行了初步的探索与研究,分析认为其愈合过程可分为裂面内凹与裂尖钝化、裂腔分节与球化和球化孔洞的缩小愈合三个部分.在与外界无物质交换的条件下,材料内部裂纹与损伤的愈合靠内部物质迁移及结构变化完成.该系列微晶玻璃的裂纹愈合主要受愈合温度的影响.
By means of heating, the pre-crack healing of mica glass ceramics was studied. The results show that there are three stages in the process of crack healing,
including crack surface concave shape and crack tip blunting, crack disintegrating and sphericizing to void and void healing. On the condition that there is no material
commutation with outside, healing of internal crack and hurt of material depends on the move of internal material and the change of structure. Crack-healing of
the series’ glass ceramics is primarily influenced by healing temperature.
