在壓力加工、鑄造、焊接、熱處理、切削加工和其他工藝過程中，制品可能產(chǎn)生內(nèi)應(yīng)力。多數(shù)情況下，在工藝過程結(jié)束后，金屬內(nèi)部將保留一部分殘余應(yīng)力。殘余應(yīng)力可導(dǎo)致工件破裂、變形或尺寸變化，殘余應(yīng)力也提高金屬化學(xué)活性，在殘余拉應(yīng)力作用下特別容易造成晶間腐蝕破裂。因此，殘余應(yīng)力將影響精密無縫鋼管的使用性能或?qū)е鹿ぜ^早失效。 </p> <p> 進(jìn)行去應(yīng)力退火時，精密無縫鋼管在一定溫度作用下通過內(nèi)部局部塑性變形(當(dāng)應(yīng)力超過該溫度下材料的屈服強度時)或局部的弛豫過程(當(dāng)應(yīng)力小于該溫度下材料的屈服強度時)使殘余應(yīng)力松弛而達(dá)到的目的。在去應(yīng)力退火時，工件一般緩慢加熱至較低溫度(灰口鑄鐵為500～550℃，精密無縫鋼管為500～650℃，有色金屬合金沖壓件為再結(jié)晶開始溫度以下)，保持一段時間后，緩慢冷卻，以防止產(chǎn)生新的殘余應(yīng)力。 </p> <p> 去應(yīng)力退火并不能完全精密無縫鋼管內(nèi)部的殘余應(yīng)力，而只是大部分。要使殘余應(yīng)力徹底，需將精密無縫鋼管加熱至更高溫度。在這種條件下，可能會帶來其他組織變化，危及精密無縫鋼管的使用性能。 </p></div><p><img
