style="text-indent:25px">溫度的影響。900℃時(shí)，氫在鐵素體中的溶解度低于2.8×10-4%，室溫下約為0.5×10-4%，溶解度變化速率約0.256×10-4%/100℃。而氫在鋼中的擴(kuò)散快慢與組織、溫度有關(guān)。氫的擴(kuò)散量既與擴(kuò)散系數(shù)成正比，又與氫在鋼中的濃度梯度成正比。不同溫度下鐵素體中氫的溶解度不同，擴(kuò)散系數(shù)也不等(圖4).擴(kuò)散系數(shù)隨溫度的降低而變小，濃度梯度與含氫量、鋼坯尺寸等有關(guān)。綜上所訴，含氫量對(duì)合金圓鋼材質(zhì)影響是比較大的，因?yàn)闅涞臄U(kuò)散濃度變大，確實(shí)會(huì)對(duì)鐵素體本身造成較為大的影響。</p><p
