</div> <div id="oejcfa0" 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(shí)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(dá)0.6%以上，說明已應(yīng)用了滲碳工藝。但當(dāng)時(shí)作為個(gè)人“手藝”的秘密，不肯外傳，因而發(fā)展很慢。 </div> <div id="dfwpssm" 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(shí)，內(nèi)部會(huì)發(fā)生組織改變，鋼中高溫時(shí)的相在急冷時(shí)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(shí)，人們還研究了在金屬熱處理的加熱過程中對金屬的保護(hù)方法，以避免加熱過程中金屬的氧化和脫碳等。
