摘要：Industrial die casting is one of the most frequent causes of material failure under extreme temperature cycling of tool working surfaces; the properties of related material should thus be optimized. The properties of die casting materials may vary significantly for a given hardness depending on the heat treatment. Heat treatment critically affects the metallurgical properties of hot-work tool steels. Specific heat treatment systems allow for high quenching velocities, and they are available on the market. These systems include vacuum systems with high-pressure nitrogen or helium-quenching, and sophisticated dual-chamber vacuum systems [1, 2]. During tool cycling, materials’ behavior is determined by tool material properties and complex interaction between thermal cycling and mechanical conditions [3, 4]. The resistance of material to tempering significantly depends on the heat treatment [5-7].
