true uniform strain 中文意思是什麼
true uniform strain
解釋
真勻應變-
The results of pure cu show ecap can produce bulk material of submicrometer level indeed. as the number of passes increases, the initial structure of pure cu has been refined largely. after six passes, i. e. the equivalent true strain of 4 ~ 5, the grain size gradually becomes stable and uniform
對純銅室溫ecap晶粒超細化行為及組織穩定性的研究表明: ecap技術的確能制備出亞微米級的塊體材料,隨著ecap道次的增加,純銅的組織被大大細化, ecap六道次(即等效真應變4 5 )后,晶粒尺寸趨于穩定,硬度基本飽和。
