Optimizing heat treatment regimes for high-strength weldable, sparingly alloyed steels

It is important to devote maximum attention to the heat treatment of temperable high-strength weldable steels (σ^sub 0.2^≥700 MPa) in which the expensive alloying elements (Cr, Ni, Mo, etc.) are partially or fully replaced by microadditives (V, Ti, etc.). The present paper concerns the effect of the...

Description
Summary:It is important to devote maximum attention to the heat treatment of temperable high-strength weldable steels (σ^sub 0.2^≥700 MPa) in which the expensive alloying elements (Cr, Ni, Mo, etc.) are partially or fully replaced by microadditives (V, Ti, etc.). The present paper concerns the effect of the temperature-and-time heat treatment parameters on the structure, the grain size, and the mechanical properties of sparingly alloyed steel 15G2KhNMFTR. The heat treatment regime is optimized.[PUBLICATION ABSTRACT]
