精密光亮管的高溫回火脆性的本質(zhì)，普遍認(rèn)為是磷、錫、銻、砷等雜質(zhì)元素在原奧氏體晶界偏聚，導(dǎo)致晶界脆化的結(jié)果。而錳、鎳、鉻等合金元素與上述雜質(zhì)元素在晶界發(fā)生共偏聚，促進(jìn)雜質(zhì)元素的富集而加劇脆化。而鉬則相反，與磷等雜質(zhì)元素有強(qiáng)的相互作用，可使在晶內(nèi)產(chǎn)生沉淀相并阻礙磷的晶界偏聚，可減輕高溫回火脆性稀土元素也有與鉬類(lèi)似的作用。鈦更有效地促進(jìn)磷等雜質(zhì)元素在晶內(nèi)沉淀，從而減弱雜質(zhì)元素的晶界偏聚減緩了高溫回火脆性。 </div> <div id="ju9j44f" class="para"> 降低精密光亮管高溫回火脆性的措施有：(1)在高溫回火后用油冷或水快速冷卻以抑制雜質(zhì)元素在晶界偏聚；(2)采用含鉬精密光亮管種，當(dāng)鋼中鉬含量增加到0．7%時(shí)，則高溫回火脆化傾向大大降低，超過(guò)此限20#精密鋼管中形成富鉬的特殊碳化物，基體中鉬含量降低，精密光亮管的脆化傾向反而增加；(3)降低20#精密鋼管中雜質(zhì)元素的含量；(4)長(zhǎng)期在高溫回火脆化區(qū)工作的部件，單加鉬也難以防止脆化，只有降低20#精密鋼管中雜質(zhì)元素含量，提高精密光亮管的純凈度，并輔之以鋁和稀土元素的復(fù)合合金化，才能有效地防止高溫回火脆性。
