摘要
从理论上分析了形成块状铁素体的原因,结合集箱实际热处理的情况,认为在P91钢中形成块状铁素体的原因是温度过高(超过A1相变点)造成的。并提出了消除块状铁素体的工艺。
the phase Analyzed theoretically the reasons for the formation of massive ferrite through analysis of diagram of P91 steel. Combined with the heat treatment of the header, we can make a conclusion that the formation of massive ferrite in P91 steel is because temperature is too high （ more than the A1 transformation point）. And the process of elimination of massive ferrite was proposed.
