The Impact of Strain Aging on the Mechanical Properties of Steel 37KhGF

Resumo

Abstract—The impact of the strain aging effect on the structural behavior and viscoplastic properties of steel 37KhGF in hot-rolled condition and after in heat treated condition and special strengthening treatment involving the imposition of a small plastic deformation (ε = 2%) and artificial aging at 250°C for 1 h was studied. The quantitative evaluation of the contribution of the strengthening mechanism and strain aging effect to the yield point was performed.
