中文摘要 | 本文探討13%Cr麻田散鐵不銹鋼輕熱軋與200~600℃回火處理後的機械性質,分別討論晶粒尺寸與回火溫度的影響。結果顯示,回火於500℃時有明顯的二次強化現象,使本實驗材料具有較高之硬度和強度與相對較低之延性和韌性;回火前的熱軋有明顯細晶效果,晶粒尺寸隨熱軋量增加而減小,細晶伴隨的高密度晶界與均勻析出的碳化物可有效阻礙裂縫連結進而提升其機械性質。 |
英文摘要 | The effect of prior hot rolling and tempering on the mechanical properties of 13% Cr MSS was studied as a function of tempering temperature and grain size. The results indicate that a secondary strengthening phenomenon in stress and hardness occurs at tempering temperature of 500°C. The grain size decreases with increasing in the rolling reduction. Fine grain leads to an increase in the density of grain boundary and the homogeneous dispersion of carbide particles, that provides a dominant action against the creak propagation and increasing the mechanical properties. |
