The Effect of Creep and Long Annealing Conditions on the Formation of the Z-Phase Particles

The influence of the temperature, applied stress, degree of creep deformation, and aging time on the formation of Z-phase (CrVN) particles in 9% Cr 10Kh9K3V2MFBR martensitic steel at temperatures of 650 and 675°С upon long aging is studied in this work. The particles with a chemical composition determined by energy dispersive spectrometry as 50% (Cr + Fe) and 50% (V + Nb) are detected and identified as particles of the Z‑phase. An increase in...
