Abstract
Structural-phase transformations in samples of high-strength low-alloy steel 17Kh2M were studied at different cooling rates simulating different processes of their welding and subsequent deformation at increment of external load. Analytical evaluation of the specific contribution of structures formed in the welding zone to mechanical property values, as well as magnitude and distribution of strains, residual inner stresses and their gradients localized along the boundaries of structural-phase components was performed.
 
 
Keywords: high-strength steel, welding simulation, structural-phase parameters, strengthening, mechanical properties, property prediction, strain localizing, local inner stresses, theoretical strength
