The authors study the aging process of sintered N14K7M5T2 marging steel at temperatures of 460-590 C with an isothermal hold of 40 min to 10 h. Electron microscopy was used. The purpose of the investigations was establishment of the type of precipitated phases and their size, form, and kinetics of growth in relation to the aging cycles. An analysis of the electrondiffraction patterns of specimens aged under different conditions made it possible to identify Ni/sub 3/ Ti as the hardening phase.
