Rapid cooling from high temperature
The supersaturated vacancies
The formation of vacancy disc and its subsequent collapse form a stacking fault bounded by a Frank partial dislocation. The Frank partial dislocation may dissociate into a low-energy stair-rod dislocation and a Shockley partial dislocation on an intersecting slip plane according to a reaction of the type
Then the Shockley partial dislocations on different (111) planes react with each other to form stair-rod dislocation according to the reaction
The distorted fringes : by strain field, which is related to the thermal stress associated with the micro-inclusions. Ex) (FeNi)23C6, Fe3C, amorphous graphite, SiC or Ni3C are trapped in the HPHT-grown diamonds.
피할 수 없는 고통은 즐겨라 is introduced, which may exceed the average stress by many tens of a percent near the inclusions, such stress concentrators may be -!!!
