Abstract

Abstract

A Gleeble-3500 thermal simulation testing machine was used to conduct thermal compression experiments on electron beam melting M35 high speed steel. The hot deformation behavior under the conditions of deformation temperature of 1 273～1 423 K and strain rate of 0.01～10 s⁻¹ was established. The evolution law of its carbide structure was studied, the thermal deformation constitutive equation of electron beam melting M35 high-speed steel, and the use of dynamic material model (DMM) to establish the electron beam melting M35 high speed steel hot processing map. At the same time, it is compared and analyzed with the hot deformation behavior of normal melting M35 high speed steel, The results show that the true stress-strain curve of electron beam melting M35 high speed steel conforms to the characteristics of dynamic recrystallization curve, the curve appears jagged at high strain rates, and the stress increases with the increase of strain rate and decrease of temperature. The deformation behavior in the hot deformation process can be characterized by a hyperbolic sine function, and its average activation energy is 504.642 kJ/mol. Through the hot processing map, the hot deformation instability area of M35 high-speed steel is intuitively displayed, and the best deformation conditions for hot working are obtained as follows: the deformation temperature is 1 400～1 423 K, and the strain rate is 0.01～1 s⁻¹ .
