    EFFECT OF DIFFERENT AGING PROCESS ON THE PROPERTIES OF 82B STEEL WIRE COIL

      Graphical Abstract
      • Abstract
    • The changes of microstructures and properties,the difference of macroscope fractography and dimple morphology of micro-fracture of 82B steel wire coil in natural aging process during 0~30 days after high-speed wire reel collecting was studied by OM,SEI technology and universal material testing machines. Artificial aging under slowly cooling conditions after heating temperature of 250 ℃ and 300 ℃,holding time of one hour was carried out. Comparison the results on mechanical properties by artificial aging and natural aging processes were showed that mechanical properties of artificial aging were about effect of natural aging at 15 days,so the production efficiency will be improved by artificial aging process.
