Study of Features of Phase Precipitate Formation, Structural State, and Properties of Nb, V-Microalloyed Low Carbon Ferritic Steels

  • Published:
Metallurgist Aims and scope

Contemporary methods of optical and transmission electron microscopy, and mechanical property tests are used to study features of phase precipitate formation, structural state, and the properties of lowcarbon V, Nb micro-alloyed steels. The effect of nano-sized carbide (carbonitride) V, Nb precipitates formed in austenite during FCC → BCC-phase transformation of steel on the structural state and implementation of different mechanisms is evaluated. Characteristics of similar Ti and Mo precipitates in micro-alloyed ferritic steels are compared.
