摘要
本文采用兼顾化学成分和热加工温度的方法来预测δ-F的形成,通过降低铁素体形成元素的含量,提高奥氏体形成元素的含量,从而获得较低的铬当量,减少了δ-F相的形成。证实了C、N、V对δ-F的形成起决定作用,有效地降低了δ-F相的含量,将δ-F相控制在5%以内,从而改善了材料0Cr17Ni4Cu4Nb的力学性能,提高其使用寿命,为新型叶片钢的开发设计、制造使用提供了可靠的参考数据。
This paper introduced a method to predict the formation of δ-F phase by considering both chemical composition and hot processing temperature by reducing the content of ferrite formation element,improve the content of austenite formation elements,to obtain a lower chromium equivalent,reducing the δ-F phase formation. It was Confirmed that the chemical composition of C,N,V play a decisive role in the formation of δ-F phase,the content of δ-F could be reduced effectively,δ-F phase will be controlled within 5%,thus improved the mechanical properties of 0Cr17Ni4Cu4Nb materials and its service life,provides reliable reference to manufacturing and development of vane steel.
