精密管中合金元素對(duì)低溫回火脆性產(chǎn)生較大的影響。鉻和錳促進(jìn)雜質(zhì)元素磷等在奧氏體晶界偏聚，從而<br /> 促進(jìn)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<br /> 以抑制低溫回火脆性。硅能推遲回火時(shí)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)<br /> 生的溫度。<br /> 膨脹系數(shù)編輯<br /> 檢查的方法可以用肥皂水抹在退火爐各個(gè)接頭縫隙處，看是否跑氣；其中容易跑氣的地方是退火爐進(jìn)<br /> 管子的地方和出管子的地方，這個(gè)地方的密封圈特別容易磨損，要經(jīng)常檢查經(jīng)常換。提出了冷彎成型前<br /> 對(duì)無(wú)錫精密鋼管進(jìn)行預(yù)處理的工藝方案;研究分析了正火溫度、保溫時(shí)間和冷卻方式對(duì)原料管組織和力學(xué)<br /> 性能的影響規(guī)律;確定了無(wú)錫精密鋼管的常規(guī)正火工藝:加熱溫度(890±10)℃,保溫6min后散置空冷。常<br /> 規(guī)正火工藝可完全無(wú)錫精密鋼管的魏氏組織,使其屈服強(qiáng)度和抗拉強(qiáng)度的匹配更加合理,屈強(qiáng)比σS/b<br /> σ≤0.78,延伸率5δ≥30%,冷成型性能大幅度提高并避免出現(xiàn)冷彎開裂現(xiàn)象。膨脹系數(shù)可以用體積或者<br /> 是長(zhǎng)度表示，通常是用長(zhǎng)度表示。密度物質(zhì)的密度是該物質(zhì)單位體積的質(zhì)量，單位是kg/m3或1b/in3。殘<br /> 余拉應(yīng)力主要來(lái)自設(shè)備在焊接過程中產(chǎn)生的殘余拉應(yīng)力。當(dāng)前，工程上廣泛采用焊接冷卻后進(jìn)行退火處<br /> 理殘余應(yīng)力，而焊后冷卻是殘余應(yīng)力產(chǎn)生的重要過程，這種做法既浪費(fèi)了能源又容易產(chǎn)生較大的焊<br /> 接殘余應(yīng)力。焊接后熱處理是一種新的殘余應(yīng)力技術(shù)。焊前將無(wú)錫精密鋼管預(yù)熱至后熱處理溫度并<br /> 在焊接過程中對(duì)焊件持續(xù)加熱保持這一溫度，焊接完成后使用保溫棉對(duì)其進(jìn)行保溫使其緩慢冷卻。淬火<br /> 能增加鋼管的強(qiáng)度和硬度，但要減少其塑性。淬火中常用的淬火劑有水、油、堿水和鹽類溶液等。無(wú)錫<br /> 精密鋼管的回火將已經(jīng)淬火的無(wú)錫精密鋼管重新加熱到一定溫度，再用一定方法冷卻稱為回火。其目的<br /> 是淬火產(chǎn)生的內(nèi)應(yīng)力，降低硬度和脆性，以取得預(yù)期的力學(xué)性能?；鼗鸱指邷鼗鼗?、中溫回火和低<br /> 溫回火三類?；鼗鸲嗯c淬火、正火配合使用。調(diào)質(zhì)處理淬火后高溫回火的熱處理方法稱為調(diào)質(zhì)處理。 </p> <p> </p></div><p><img

<p> 1.外徑更小。 </p> <p> 2.精度高可做小批量生產(chǎn)。 </p> <p> 3.冷拔成品精度高，表面質(zhì)量好。 </p> <p> 4.鋼管橫面積更復(fù)雜。 </p> <p> 5.鋼管性能更優(yōu)越，金屬比較密。 </p> <p> 脆化現(xiàn)象 </p> <p> 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 </p> <p> 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 </p> <p>

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 </p> <p> 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(shí)發(fā)生奧氏體 </p> <p> 晶界偏聚，淬火后保留下來(lái)。磷在原奧氏體晶界偏聚和滲碳體回火時(shí)在原奧氏體晶界析出，這兩個(gè)因素
