Effect of strain aging on the temperature dependence of the components of impact toughness
- 18 Downloads
Strain aging of low-carbon steel affects mainly the ductilebrittle transition temperature, as the result of which the percentage of ductile components in the fracture and consequently the toughness change at a certain testing temperature.
The lower work of crack propagation under the influence of deformation and aging is due to the lower density of mobile dislocations.
