摘要： A tool steel family with outstanding thermal diffusivity, hardness and wear resistance has been developed, also exhibiting good hardenability. Also its mechanical strength, as well as its yield strength, at ambient and high temperature (superior to 600°C) are high, due to a high alloying level in spite of the high thermal conductivity. Because of its high thermal conductivity and good toughness, steels of this invention have also good resistance to thermal fatigue and thermal shock. This steels are ideal for discontinuous processes where it is interesting to reduce cycle time and that require high hardness and/or wear resistance (plastic injection molding, other plastic forming processes and curing of thermosets, hot forming of sheet...). These tool steels are also appropriate for processes requiring high wear resistance and good resistance to thermal fatigue (forging, hot stamping, light-alloy injection...).

摘要： The present invention relates to a tool steel as described in WO2012095532A1 or WO2010112319A1 and its heat treatment where high levels of thermal diffusivity, mechanical resistance, wear resistance and/or toughness are attained while having a low cracking risk during the heat treatment. It is achieved by austenitizing at a temperature, normally above AC
3 , cooling to an intermediate temperature below AC
1 and above the temperature where bainitic (and alike) transformation occurs and finally quenching with a severe cooling media to a temperature below the bainitic transformation nose. Final microstructure is mainly composed of martensite and/or lower bainite, which will generally be afterwards tempered.

摘要： A method to manufacture a forming tool, which method can be used in material shaping processes involving heat transference from the shaped part into the forming tool and from the latter to a cooling medium, through the provision of a permanent or semi-permanent isolating and/or releasing layer over the in-cavity surface of the die in combination with the use of high thermal conductivity materials for the die. This method allows to severely reduce the manufacturing cost of the produced part through productivity/durability optimization and continuous monitoring of the process. The system is applicable for all material forming processes involving the heat transfer from the formed part to the forming tool and cooling down of this later during the consecutive forming cycles, in particular for High pressure die casting, semi-solid die casting, squeeze casting, hot forging, hot glass forming and tube manufacturing amongst others.

摘要： A manufacturing method for dies, moulds and unique pieces or for a small quantity by means of forging in a forming mould is provided. The method consists in the construction of a forming mould which is able to bear high temperatures and mechanical stressing which occur when forging material in a closed system. It does not matter if the forming mould is destroyed during the forging process if the material of the mould, die or piece is deformed; the forming mould is sufficiently economically so that its cost does not exceed the cost reduction in relation to the machining process. The materials which are used for the construction of the forming mould should be the most economical, but they must have the thermal and mechanical characteristics which are necessary for the forging process. In particular, preferred materials for the moulds are mortar and concrete with cements of a high resistance, with refractory cements, with basaltic aggregates, sand and other refractory aggregates, and other aggregates which are normally used for construction. Also other mortars can be used.
