本文介绍了18％Ni马氏体时效钢相变诱发塑性的初步研究与应用。对18％Ni马氏体时效钢的相变诱发塑性与温度、应变速度等因素的关系进行了分析选择,并将所选最佳参数应用于半球形件的成形和整形,使一批有缺陷的半球形件成为合格产品.取得了明显的效益。这种方法可以推广使用。
This paper introduces the preliminary study and application of phase transition induced plasticity of 18% Ni martensitic steel. The relationship between the phase transition induced plasticity of 18% Ni martensitic steel and the temperature and strain rate was analyzed and selected. The selected optimal parameters were applied to the forming and shaping of hemispherical parts, Of the hemispherical pieces of qualified products have achieved significant benefits. This method can be used widely.
