拉拔钨丝工艺过程中抗拉强度的控制

摘要

The tensile strength of tungsten wire is enhanced with theincreasing of deformation force.So the key of producing high－ quality tungsten wire is to control the decreasing rate of tensile strength reasonably in the process of annealing.%钨丝的抗拉强度是随变形程度增大而增高，合理地控制退火工序前后的抗拉强度下降比例是生产高质量钨丝的关键。
