brittle fracture surface 中文意思是什麼
brittle fracture surface
解釋
脆性斷裂面-
It seems the ncz silicon has a higher bdt temperature compared with cz silicon ' s. it is suggested that the elastic effects and the electronic effects of nitrogen doped in silicon made the bdt temperature higher. the observation of fracture surface showed that it was curves at high temperature in brittle fracture, but smooth planes at room temperature
當溫度升高達到硅材料的脆塑轉變時,材料的斷裂強度有個很大的提高,但是首次發現含氮硅單晶卻不明顯,而且摻氮的硅單晶脆塑轉變溫度比普通單晶高,可能是氮的摻入改變了硅材料的內部晶體結構及電子結構。 -
The results show that the fracture surface is characterized by a combination of most intergranular brittle regions and a few cleavage regions, and there are finer precipitations on grainboundaries
結果表明,成型模裂紋斷口形態呈沿晶特徵,沿晶面上有細小析出物,為脆性斷裂。 -
Brittle fracture surface
脆性斷裂面 -
What ' s more, the amount of oxygen precipitates, dislocations in silicon and the orientation of the pressed surface also influence the fracture strength. stress - strain curves were studied at room temperature. in another experiment, brittle - ductile transition ( bdt ) of ncz and cz were studied for first time
常溫下氮硅單晶( ncz )及普通硅單晶( cz )的斷裂強度研究發現,氮的摻入提高了機械性能,並且不同氧沉澱量、位錯的存在及不同晶向對硅材料機械強度也有較大影響。
