Phenomena of mechanical twinning, constitutional supercooling, inclusions of the stoichiometric LiNbO_3 crystal grown by double crucible Czochralski method were observed and analyzed in this paper.
本文对采用双坩埚提拉法(DCCZ)生长的化学计量比LiNbO3晶体中出现的机械双晶、组分过冷、包裹体等宏观生长缺陷进行了观察和分析。
Many twins identified as mechanical twins appear at the bottom of the as grown crystal.
在用掺钾的助熔剂提拉法生长近化学计量比LiNbO3 晶体时,长出的晶体尾部很容易出现孪晶裂纹现象,这种孪晶被认为是机械孪晶。
The results showed that microstructure after CSR consists of a large number of mechanical twins.
结果表明:异步轧制后显微组织中出现大量机械孪晶;样品表面粗糙度显著降低,硬度明显提高。
We suggested that local high pressure has influence on mechanical crystallization,and discussed the effect of local high pressure on amorphous crystallization.
