精密光亮管的高溫回火脆性的本質(zhì)，普遍認為是磷、錫、銻、砷等雜質(zhì)元素在原奧氏體晶界偏聚，導(dǎo)致晶界脆化的結(jié)果。而錳、鎳、鉻等合金元素與上述雜質(zhì)元素在晶界發(fā)生共偏聚，促進雜質(zhì)元素的富集而加劇脆化。而鉬則相反，與磷等雜質(zhì)元素有強的相互作用，可使在晶內(nèi)產(chǎn)生沉淀相并阻礙磷的晶界偏聚，可減輕高溫回火脆性稀土元素也有與鉬類似的作用。鈦更有效地促進磷等雜質(zhì)元素在晶內(nèi)沉淀，從而減弱雜質(zhì)元素的晶界偏聚減緩了高溫回火脆性。 </div> <div id="uzvvezb" class="para"> 降低精密光亮管高溫回火脆性的措施有：(1)在高溫回火后用油冷或水快速冷卻以抑制雜質(zhì)元素在晶界偏聚；(2)采用含鉬精密光亮管種，當鋼中鉬含量增加到0．7%時，則高溫回火脆化傾向大大降低，超過此限20#精密鋼管中形成富鉬的特殊碳化物，基體中鉬含量降低，精密光亮管的脆化傾向反而增加；(3)降低20#精密鋼管中雜質(zhì)元素的含量；(4)長期在高溫回火脆化區(qū)工作的部件，單加鉬也難以防止脆化，只有降低20#精密鋼管中雜質(zhì)元素含量，提高精密光亮管的純凈度，并輔之以鋁和稀土元素的復(fù)合合金化，才能有效地防止高溫回火脆性。

公元前六世紀，45#精密鋼管兵器逐漸被采用，為了提高鋼的硬度，淬火工藝遂得到迅速發(fā)展。中國河北省易縣燕下都出土的兩把劍和一把戟，其顯微組織中都有馬氏體存在，說明是經(jīng)過淬火的。 </div> <div id="et4wp9c" class="para"> 隨著淬火技術(shù)的發(fā)展，人們逐漸發(fā)現(xiàn)淬冷劑對淬火質(zhì)量的影響。三國蜀人蒲元曾在今陜西斜谷為諸葛亮打制3000把刀，相傳是派人到成都取水淬火的。這說明中國在古代就注意到不同水質(zhì)的冷卻能力了，同時也注意了油和尿的冷卻能力。中國出土的西漢(公元前206～公元24)中山靖王墓中的寶劍，心部含碳量為0.15～0.4%，而表面含碳量卻達0.6%以上，說明已應(yīng)用了滲碳工藝。但當時作為個人“手藝”的秘密，不肯外傳，因而發(fā)展很慢。 </div> <div id="fp809dm" class="para"> 1863年，英國金相學(xué)家和地質(zhì)學(xué)家展示了鋼鐵在顯微鏡下的六種不同的金相組織，證明了鋼在加熱和冷卻時，內(nèi)部會發(fā)生組織改變，鋼中高溫時的相在急冷時轉(zhuǎn)變?yōu)橐环N較硬的相。法國人奧斯蒙德確立的鐵的同素異構(gòu)理論，以及英國人奧斯汀早制定的鐵碳相圖，為現(xiàn)代45#精密鋼管熱處理工藝初步奠定了理論基礎(chǔ)。與此同時，人們還研究了在金屬熱處理的加熱過程中對金屬的保護方法，以避免加熱過程中金屬的氧化和脫碳等。
