摘要:Strain hardening is one of the simplest and effective means of adding fatigue strength to an alloy. Widely known strain hardening methods deform alloys by solid elements. Such mechanism is poorly suited for alloys that are operated at high temperatures. In this case, the positive effect is weakened. The reason lies in the relaxation processes that return the alloy to its original state. The stronger the plastic deformation is, the faster this process proceeds. The paper presents the technology and equipment of thermoplastic hardening, which makes it possible to increase the fatigue strength without significant plastic deformation. The effect of thermoplastic hardening persists for a long time. Due to this, the method is well suited for the turbine blades.
