hot ductility test 中文意思是什麼
hot ductility test
解釋
高溫延性試驗-
Based on the hot tensile test results, there exists a cooling rate at which a minimum reduction in area occurs and the hot ductility of the sn - doped steel is worse than that of the sn - undoped steel. when the cooling rate is lower or higher than 10 / s, the hot ductility is increased
連續冷卻到750 800范圍內拉伸時,存在一個冷卻速率( 10 s ) ,以這個冷卻速率進行冷卻,試樣的斷面收縮率最小,熱塑性最差;當冷卻速率大於或者小於這個冷卻速率時,試樣的斷面收縮率均會增大,熱塑性增強。
