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力。殘余應力可導致工件破裂、變形或尺寸變化，殘余應力也提高金屬化學活性，在殘余拉應力作用下特別容易造成晶間腐蝕破裂。因此，殘余應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> 進行去應力退火時，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(當應力超過該溫度下材料的屈服強度時)或局部的弛豫過程(當應力小于該溫度下材料的屈服強度時)使殘余應力松弛而達到的目的。在去應力退火時，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)生新的殘余應力。 </p> <p> 去應力退火并不能完全精密無縫鋼管內(nèi)部的殘余應力，而只是大部分。要使殘余應力徹底，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 src="http://2024aiimg.qy55.com//cjjhb_soft/142/1249/202402220322382524.jpg"

/> 精密鋼管進行塑性變形時，金屬的強度和硬度升高，而其塑性和韌性下降的現(xiàn)象稱為冷變形強化（也稱為加工硬化）。產(chǎn)生冷變形強化的原因，通常被認為在塑性變形過程中，隨變形量的增加，位錯密度增加，并發(fā)生一系列交互作用，使位錯運動受阻；同時晶粒也會出現(xiàn)破碎，變成細條狀，晶界變得模糊不清，形成所謂的"纖維組織"。無錫精密鋼管的變形程度愈大，位錯密度愈高，位錯運動的阻力愈大，塑性變形抗力也愈大，則其強度和硬度升高，而塑性韌性下降。
