根據(jù)精密管產(chǎn)生脆性的回火溫度范圍，可分為低溫回火脆性和高溫回火脆性。 </p> <p> 精密管低溫回火脆性合金鋼淬火得到馬氏體組織后，在250～400℃溫度范圍回火使鋼脆化，其韌性一脆性轉(zhuǎn)化溫度明顯升高。已脆化的精密管不能再用低溫回火加熱的方法，故又稱為%26ldquo;不可逆回火脆性%26rdquo;。它主要發(fā)生在合金結(jié)構(gòu)鋼和低合金超高強度精密管等鋼種。已脆化精密管的斷口是沿晶斷口或是沿晶和準(zhǔn)解理混合斷口。產(chǎn)生低溫回火脆性的原因，普遍認(rèn)為：(1)與滲碳體在低溫回火時以薄片狀在原奧氏體晶界析出，造成晶界脆化密切相關(guān)。(2)雜質(zhì)元素磷等在原奧氏體晶界偏聚也是造成低溫回火脆性原因之一。含磷低于0.005%的高純精密管并不產(chǎn)生低溫回火脆性。磷在火加熱時發(fā)生奧氏體晶界偏聚，淬火后保留下來。磷在原奧氏體晶界偏聚和滲碳體回火時在原奧氏體晶界析出，這兩個因素造成沿晶脆斷，促成了低溫回火脆性的發(fā)生。 </p> <p> 精密管中合金元素對低溫回火脆性產(chǎn)生較大的影響。鉻和錳促進雜質(zhì)元素磷等在奧氏體晶界偏聚，從而促進低溫回火脆性，鎢和釩基本上沒有影響，鉬降低低溫回火精密管的韌性一脆性轉(zhuǎn)化溫度，但尚不足以抑制低溫回火脆性。硅能推遲回火時滲碳體析出，提高其生成溫度，故可提高精密管低溫回火脆性發(fā)生的溫度。 </p></div><p><img

真空退火優(yōu)質(zhì)彈簧鋼、工具鋼、精密鋼管的絲材，不銹鋼制品及鈦合金材，作光亮退火均可采用真空處理。退火溫度愈低，則要求真空度愈高。為防止鉻的蒸發(fā)及加速熱傳導(dǎo)，一般采用載氣加熱(保溫)法，并注意對不銹鋼和鈦合金不宜用氮而應(yīng)采用氬氣。<br /> 過程 </p> <p> 真空淬火真空淬火爐按冷卻方法分為油淬和氣淬兩類，按工位數(shù)分為單室式和雙室式，904山\畏嘲均屬周期式作業(yè)爐。真空油淬爐都是雙室的，后室置電加熱元件，前室的下方置油槽。工件完成加熱、保溫后移入前室，關(guān)閉中門后向前室充入惰性氣至大約2．66%26times;lO ～1．01%26times;10 Pa(200～760mm汞柱)，入油。油淬易引起工件表面變質(zhì)。由于表面活性大，在短暫的高溫油膜作用下即可發(fā)生顯著薄層滲碳，此外，碳黑和油在表面的粘附對簡化熱處理流程很不利。真空淬火技術(shù)的發(fā)展主要在于研制性能優(yōu)良、工位單一的氣冷淬火爐。前述雙室式爐亦可用于氣淬(在前室噴氣冷卻)，但雙工位式的操作使大批量裝爐的生產(chǎn)發(fā)生困難，也易在高溫移動中引起工件變形或改變工件方位增加淬火變形。單一工位的氣冷淬火爐是在加熱保溫完成后在加熱室內(nèi)噴氣冷卻。氣冷的冷速不如油冷快，也低于傳統(tǒng)淬火法中的熔鹽等溫、分級淬火。因而，不斷提高噴冷室壓力，增大流量，以及采用摩爾質(zhì)量比氮和氬小的惰性氣體氦和氫，是當(dāng)今真空淬火技術(shù)發(fā)展的主流。70年代后期將氮氣噴冷的壓力從(1～2)%26times;10Pa提高到(5～6)%26times;10Pa，使冷卻能力接近于常壓下的油冷。80年代中期出現(xiàn)超高壓氣淬，用(10～20)%26times;10Pa的氦，冷卻能力等于或略高于油淬，已進入工業(yè)實用。90年代初采用40%26times;10Pa的氫氣，接近水淬的冷卻能力，尚處于起步階段。工業(yè)發(fā)達已進展到以高壓(5～6)%26times;10。Pa氣淬為主體，而中國產(chǎn)氣淬一些金屬的蒸氣壓(理論值)與溫度的關(guān)系則尚處于一般加壓氣淬(2%26times;10Pa)型階段。
