Definitions
- the present invention relates to a Nickel-based composition for high thermal resistance elements, in particular for hot deformation tools and for high- temperature working. Specifically, this composition is suitable to the forming of tools apt to work under 10 extremely onerous thermal conditions, liable to be subjected to thermal cycles of wide thermal ranges.
- Analogous tools are, e.g., dies, cutting tools and the like.
- a field requiring high-performance compositions, 15 combined with a satisfactory machinability, is represented by forging, in which the die and the forged piece have the same temperature .
- This technique enables to hot-roll products characterised by low thicknesses and volumes, yet 20 exhibiting stable and uniform mechanic properties.
- thermomechanical distortions can substantially speed up the related manufacturing processes, dispensing with burdensome finishing interventions like grinding, shaping, etc.
- Nickel-based composition is that of US Pat. No.5, 538, 683 (Pinnow et al . ) .
- the technical problem underlying the present invention is to provide a Nickel-based composition for high thermal resistance elements allowing to attain improved performances, with respect to the known art.
- This problem is solved by a composition for high thermal resistance elements, in particular for hot deformation tools and for high temperature working, characterised in that it comprises: a Nickel (Ni) content ranging from 57.0% to 62.0%; a maximum Tungsten (W) content of 10.0%; and a maximum Iron (Fe) content of 1.5%.
- the present invention further relates to a tool formed with the composition as hereto set forth, and in particular to such a forging die.
- a tool formed with the composition as hereto set forth, and in particular to such a forging die.
- Fig. 1 is a schematic sectional view of a die-die block complex made with the composition according to the invention.
- FIG. 2 is a schematic elevational view of a press employing the die of Fig. 1.
- a forging-type die is indicated with 1.
- Such a die when it is employed in the forming of metal workpieces, should be capable of being subjected to extremely elevated heating of up to 1100°C and above, to be subsequently cooled down with an optimum distortion control .
- the temperatures are lower, yet the working conditions are equally severe, also in light of the fact that for this type of workpieces an elevated manufacturing speed and the utmost accuracy, sometimes such as to dispense with further finishing steps, are expected.
- a die 1 comprises a (male) top counter plunger 2, housed in a suitable die block 3, and a bottom die block 4, housing a (female) matrix die 5.
- a matrix die 5 Through the matrix die 5 two guide grooves 6 for inserting ejection tools, and at least one injection runner 7 having a profile divergent towards the inside of the former, are formed.
- the counter plunger 2 and the matrix die 5 are connected by screw-type fastening means (not shown in Fig.) and dowel pins 8.
- the press adjusting, cooling and injecting means 11 are of traditional type, and therefore a further description thereof will be omitted.
- Ni Nickel
- W Tungsten
- Fe Iron
- composition it has a Chromium (Cr) content of above 6%, moreover comprising Manganese (Mn) , Silica (Si) , Carbon (C) and Molybdenum (Mo) .
- Example 1 Two embodiments of the abovedisclosed composition, of course by way of example and not for limitative purposes example, will hereinafter be disclosed.
- Example 1 Two embodiments of the abovedisclosed composition, of course by way of example and not for limitative purposes example, will hereinafter be disclosed.
- composition disclosed in the present example is used in order to obtain a material of elevated purity, of highly refined structure, and remarkable isotropic properties, the latter being particularly useful in dies subjected to remarkable mechanical stresses and in particular to thermal fatigue (e.g., dies for pressure die-casting, dies for hot-pressing and matrix dies for aluminium and copper alloy extrusions) .
- composition disclosed in the present example is used in order to obtain a material enabling a decreased friction coefficient, also avoiding deformation and stress during ejection, in particular decreasing the sliding friction, important for an easy filling up of the cavities even at low temperatures and with a low pressure, and for an anticipated and easier post- solidification ejection.
