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有著良好的熱疲勞性能。合金圓鋼根據(jù)標(biāo)準(zhǔn)或需方要求進(jìn)行卷邊試驗(yàn)。</p><div
