摘要
采用振动时效（ＶＳＲ）和热时效两种方法对核电堆内构件３０４Ｌ不锈钢方形筒体（控制棒导向筒）进行焊后去应力处理。通过对残余应力和工艺变形测定，表明这两种方法都可达到期望的技术要求。对振动时效的机理及动应力对去应力效果的影响作了较详细的介绍，并对两种工艺进行了比较。
One of the nuclear reactor internals,stainless square tube (conduit of control cylinder),has been treated with VSR(Vibrate Stress Relief)and heat treatment respectively.The two methods have been proved to meet the need of expected technique according to the measurement result of residual stress and deformation.The paper
