In cold-work applications, tool steels with high carbide contents are used as cutting and stamping tools. The service life is limited by wear resistance fatigue strength. relationship between manufacturing-related microstructural influences strengths of has not yet been adequately investigated. To investigate these on high-cycle (HCF) strength (NG = 107), rotating bending tests performed AISI D...

Many efforts have been made to model the the hot deformation (dynamic recrystallization) flow curves of different materials. Phenomenological constitutive models, physical-based constitutive models and artificial neural network (ANN) models are the main methods used for this purpose. However, there is no report on the modeling of warm deformation (dynamic spheroidization) flow curves of any kin...
