Thermo-Mechanic Treatments Influence on Plastic Deformation Strength of High Speed Steel

Abstract

In this paper is presented for the tool steel Rp5 the evolution of the strength at deformation depending on two parameters (the temperature and the deformation speed). For the determination of equation what makes the connection between the strength at deformation and parameters it was used results of the experimental trials effected for different of temperatures but and for different speeds. On the basis of the experimental results and established equation, it was possible to be calculated the plastic deformation strength values for different temperatures and speeds. Knowing the strength at deformation may be chosen the deformation process with that is deformed the tool steel Rp5.
