(Ti, V)C dispersion strengthened 304 stainless steel was fabricated by in-situ reaction technology. Microstructure observation reveals that the distribution of the added (Ti, V)C particles with the size of 4-10 μm is basically uniform in the matrix, but slight aggregation of particles is observed in a few areas in the microstructure. The addition of the (Ti, V)C particles into the 304 stainless steel results in a significant increase of the tensile strength at both the room temperature and the high temperature, but a decrease of the ductility and the toughness. Compared with the 304 stainless steel matrix, the creep resistance of the 304 steel strengthened with the addition of the (Ti, V)C particles increases notably at the temperature of 700℃ and the applied stress of 100 MPa. ©, 2015, Chinese Mechanical Engineering Society.
