Fracture toughness and wear resistance of hot work tool steel related to heat treatment conditions

Podgornik Bojan - IMT (Slovenia)

The procedure we are using to measure fracture toughness, effect of composition and heat treatment parameters on fracture toughness and other mechanical properties, possibilities to model response of hot work tool steels on different heat treatment parameters depending on the composition, effect of processing routes – ESR, conventional etc. and different inclusions/defects on properties and finally about heat treatment parameters and incorporation of deep cryogenic treatment on wear resistance of hot work tool steels and how abrasive wear resistance depends on fracture toughness and hardness.
