surface grain oxidation 中文意思是什麼
surface grain oxidation
解釋
表面晶粒氧化-
( 1 ) oxidation on the crack surface of 16mnr increase with temperature. oxidation mainly takes place on the crack surfaces at 150 ~ 300, which it is serious both on the crack surfaces and in the grain boundaries at 425. oxide - induced closure at 150 ~ 300 results in the drop of crack growth rates
鐵素體材料16mnr疲勞裂紋表面的氧化隨溫度升高而增大,在150和300時裂紋表面氧化引進的閉合效應要比晶界氧化脆化更明顯,引起在這個溫度范圍內的試驗疲勞裂紋擴展速率下降。
