单晶体红宝石三维内应力测定

MEASUREMENT OF INTERNAL STRESSES OF THREE DIMENSIONS IN RUBY SINGLE CRYSTALS

通过应用赝Kossel背射一次曝光法,测量焰熔法生长的红宝石晶体八个方向的应变量,并对与之相应的平均应变张量和应力张量进行求解,测出红宝石晶体的三维内应力.上述方法是分析单晶体应变和应力结构的一个有效方法.

Internal strains in eight different directions in ruby single crystals are measured from the reflection pseudo-Kossel pattern. By solving the corresponding average strain and stress tensors, the internal stresses of three dimensions in the crystals can be calculated. Since internal stress is an important parameter for appraising the quality of rudy, the method mentioned above is recommendable.
