就要設(shè)法增大位錯運動的阻力。金屬中的強化機制主要有固溶強化、位錯強化、細(xì)晶強化、第二相（沉淀和彌散）強化。合金元素的強化作用, 正是利用了這些強化機制。對退火狀態(tài)下鋼的機械性能的影響：結(jié)構(gòu)鋼在退火狀態(tài)下的基本相是鐵素體和碳化物。合金元素溶于鐵素體中, 形成合金鐵素體, 依靠固溶強化作用, 提**度和硬度, 但同時降低塑性和韌性。對退火狀態(tài)下鋼的機械性能的影響：由于合金元素的加入降低了共析點的碳含量、使C曲線右移, 從而使組織中的珠光體的比例增大, 使珠光體層片距離減小, 這也使鋼的強度增加, 塑性下降。合金鋼板檢測儀器原名QL-HW2000B高頻紅外碳硫分析儀。鎮(zhèn)江GCR15合金板</p><p style="text-indent:25px">按金相組織分：珠光體鋼、馬氏體鋼、鐵素體鋼、奧氏體鋼、萊氏體鋼。鎮(zhèn)江GCR15合金板</p><p style="text-indent:25px">但是合金元素在退火狀態(tài)下, 合金鋼沒有很大的優(yōu)越性。由于過冷奧氏體穩(wěn)定性增大, 合金鋼在正火狀態(tài)下可得到層片距離更小的珠光體, 或貝氏體甚至馬氏體組織, 從而強度大為增加。Mn、Cr、Cu的強化作用較大, 而Si、Al、V、Mo等在一般含量（例如一般結(jié)構(gòu)鋼的實際含量）下影響很小。對淬火、回火狀態(tài)下鋼的機械性能的影響：合金元素對淬火、回火狀態(tài)下鋼的強化作用比較明顯, 因為它充分利用了全部的四種強化機制。淬火時形成馬氏體, 回火時析出碳化物, 造成強烈的第二相強化，同時使韌性極大改善, 故獲得馬氏體并對其回火是鋼的比較經(jīng)濟和比較有效的綜合強化方法。鎮(zhèn)江GCR15合金板</p><p
