style="text-indent:25px">合金圓鋼變形造成拉縮與起槽因素：拔制方法：將長(zhǎng)芯櫸拔制法與短芯櫸拔制法相比，長(zhǎng)芯棒拔制時(shí)減輕了合金圓鋼內(nèi)孔表面的軸向張應(yīng)力，因此戒輕了拉縮與起槽現(xiàn)象，在變形系數(shù)相同的條件下，短芯櫸拔制有明見的相痕，而長(zhǎng)芯掙拔制則無。減徑量：當(dāng)減徑量較大時(shí)，一方面合金圓鋼在減徑區(qū)內(nèi)處于空拔狀態(tài)，容易失穩(wěn)，使管壁彎曲而加深內(nèi)槽深，另一方面，由于在成徑過程中，薄壁部分的壁厚有所增加，增加了減壁區(qū)的不均勻變形，也增大了拉縮和起槽。因此，在拔制異壁異型管時(shí)，應(yīng)盡量采用較小的減徑量。</p><p style="text-indent:25px">熱疲勞是指在進(jìn)行加熱（膨脹）和降溫（收縮）的過程中，當(dāng)溫度發(fā)生變化和受到來自外部的約束力時(shí)，在合金圓鋼的內(nèi)部相應(yīng)于其本身的膨脹和收縮變形產(chǎn)生應(yīng)力，并使材料發(fā)生損傷。當(dāng)快速地反復(fù)加熱和降溫時(shí)其應(yīng)力就具沖擊性，所產(chǎn)生的應(yīng)力與通常情況相比更大，此時(shí)有的合金圓鋼呈脆性破壞。這種現(xiàn)象被稱之為縶沖擊。熱疲勞和熱沖擊是有著相似之處的現(xiàn)象，但前者主要伴隨大的塑性應(yīng)變，而后者的破壞主要是脆性破壞。合金的成分和熱處理?xiàng)l件對(duì)高溫疲勞強(qiáng)度有影響。特別是當(dāng)碳的含量增加時(shí)高溫疲勞強(qiáng)度明顯提高，固溶熱處理溫度也有顯著的影響。一般來說鐵素體型合金具有良好的熱疲勞性能。在合金中，高硅的且在高溫下具有良好的延伸性的牌號(hào)有著良好的熱疲勞性能。合金圓鋼將在各個(gè)領(lǐng)域帶來全新的改觀。</p><div
