【摘要】 在充分研究了强碳化物形成元素对合金钢回火转变的影响机理和规律基础之上,利用计算机对强碳化物形成元素,回火温度(400℃～77℃)与钢间的关系进行了多元回归分析.所建立的多元回归方法具有很高的显著性(α=0.01),可依据合金元素的种类、含量及回火温度较精确地预测钢的硬度,并为合金成分的设计和回火工艺的制订提供了理论指导.更多还原

【Abstract】 Based on the analysis of the effect of the strong carbide-forming elements on tempering transformation, multi-factor regression of the relationship among strong carbide-forming elements,tempering temperature(400℃-700 ℃) and hardness of the steel has been carried out by means of computer.The given multi-factor regression equation has high prominence(α=0.01),in which the hardness can be precisely forecast according to the kind and content of the elements and the tempering temperature.The result would offer a theoretical guidance 1o disign alloy composition and fomulate tempering process.更多还原
