Abstract: The properties of alloys are strongly influenced by the adopted processing route and its parameters, as well as by the execution of suitable thermal or mechanical treatments or by a their suitable combination. The paper aims to focus on the fundamental of the effects produced by heat treatments on tool steels, with particular reference to the influence of the alloying elements, as well as of the process parameters. A case study applied to two different grades of high speed steels is presented, with particular reference to the influence of the treatment temperature on the mechanical and micro structural properties.
Keywords: physical metallurgy; microstructure; material properties; alloying elements; hardness; carbides; wear resistance; heat treatment; tool steels; high speed steels; mechanical properties; alloys.
