The precipitation behavior of Z -phase was investigated during long-term aging at 650°C in an ultra low carbon 9 Cr 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°C for 1h, cooled in air and tempered at 700°C for 1h. 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°C 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 [Formula: see text].
