冷軋精密光亮鋼管的冷脆性(或低溫脆化傾向)用韌性一脆性轉(zhuǎn)化溫度Tc表示。高純鐵(0.01%C)的Tc在一100C，低于此溫度則完全處于脆化狀態(tài)。冷軋精密光亮鋼管中大多數(shù)合金元素都升高冷軋精密光亮鋼管的韌性一脆性轉(zhuǎn)化溫度，增加冷脆傾向。在室溫以上韌性斷裂時(shí)，冷軋精密光亮鋼管的斷口為韌窩型斷口，而在低溫下脆性斷裂時(shí)為解理斷口。冷軋精密光亮鋼管的低溫脆化的原因是：(1)形變時(shí)位錯(cuò)源產(chǎn)生的位錯(cuò)被障礙物(如晶界、第二相等)阻塞時(shí)，局部應(yīng)力超過冷軋精密光亮鋼管的理論強(qiáng)度而產(chǎn)生微裂紋。(2)幾個(gè)塞積的位錯(cuò)在晶界合成一個(gè)微裂紋。(3)兩個(gè){110)滑移帶相交處反應(yīng)，引起不動(dòng)位錯(cuò)%26lt;010%26gt;，呈楔形微裂紋，它可沿{100}解理面裂開(見圖1b)。 </p> <p> 增加冷軋精密光亮鋼管冷脆的因素有：(1)固溶強(qiáng)化元素。磷升高韌性一脆性轉(zhuǎn)化溫度強(qiáng)烈；還有鉬、鈦和釩；含量低時(shí)影響不大而含量高時(shí)升高韌性一脆性轉(zhuǎn)化溫度的元素有，硅、鉻和銅；降低韌性一脆性轉(zhuǎn)化溫度的有鎳，先降低后升高韌性一脆性轉(zhuǎn)化溫度的有錳。(2)形成第二相的元素。以第二相增加冷軋精密光亮鋼管冷脆重要的元素為碳，隨冷軋精密光亮鋼管中碳含量增加，冷軋精密光亮鋼管中珠光體含量增加，平均每增加1%珠光體體積，韌性一脆性轉(zhuǎn)化溫度平均升高2．2℃。圖2為鐵素體一珠光體鋼中碳含量對(duì)脆性的影響。加入鈦、鈮和釩等微合金化元素，形成彌散分布的氮化物或碳氮化物，引起冷軋精密光亮鋼管的韌性一脆性轉(zhuǎn)化溫度上升。(3)晶粒尺寸影響韌性一脆性轉(zhuǎn)化溫度，隨晶粒粗化，韌性一脆性轉(zhuǎn)化溫度升高。細(xì)化晶粒則降低冷軋精密光亮鋼管的冷脆傾向，這是廣為應(yīng)用的方法。

光亮退火可保持精密鋼管外表光亮、尺寸精度，越來越受到客戶的青睞。 </p> <p> 在保護(hù)氣氛中實(shí)現(xiàn)的表面無氧化和不脫碳的冷軋板帶退火。保護(hù)氣氛有單一的惰性氣體氬或氦，也有混合氣體CO-H2-N2-CO2(DX)，N2-H2(HNX)，N2-CO2-H2等。這些混合氣體中的成分經(jīng)過調(diào)整能使帶鋼退火過程中的氧化與還原、脫碳與滲碳速度相等，從而實(shí)現(xiàn)板帶的無氧化和無脫碳的退火。退火后板帶表面有不可見的氧化膜，保護(hù)金屬光澤。 </p> <p> 根據(jù)爐氣與鋼的化學(xué)反應(yīng)及其變化規(guī)律，制備和應(yīng)用保護(hù)氣氛，確定防止氧化和脫碳的條件。CO2和H2O能使帶鋼表面氧化和脫碳；CO和CH2能使帶鋼表面氧化層還原和鋼表面滲碳；H2雖然能使氧化層還原，也能使鋼表面脫碳。光亮退火因素取決于H2O、CO2、H2氣氛和Fe的氧化還原反應(yīng)。N2和其他惰性氣體是鋼的中性保護(hù)氣氛，其中N2應(yīng)用多，但必須除去其中的氧性化氣氛，方能起到良好的保護(hù)作用。一般常用N2與H2的混合保護(hù)氣氛。
