THE Z-PHASE IN 9Cr FERRITIC/MARTENSITIC HEAT RESISTANT STEEL
The precipitation behavior of Z-phase was investigated during long-term aging at 650℃ in an ultra low carbon 9Cr ferritic/martensitic heat resistant steel. The steel was prepared by vacuum induction melting followed by hot forging and rolling into a plate. The plate was normalized at 1100℃ for 1h, cooled in air and tempered at 700℃ for 1 h. Bimodal nano-sized MX precipitates distribute densely and homogeneously in the matrix within martensitic lath after normalizing-and-tempering heat treatment. After aging at 650℃ for 1200h, the Z-phase was found to nucleate on the larger nano-sized MX. The Z-phase and MX have the following orientation relationship: <112>Z-phase//<001>mx and(110)Z-phaxe//(200)Mx.
