Definitions
- the invention relates to a golf club head, which at least partially consists of a stainless, precipitation hardened maraging steel.
- Such a golf club head is known, for example, from the published US patent application 20020045490.
- At least the striking plate of the golf club head shown there which has a hollow construction, consists of a precipitation-hardened, rust-free maraging steel with a martensite temperature Ms> 130 ° C.
- the maraging steel shown there has a chromium content of 10.0% to 11.5% by weight
- This maraging steel is precipitation hardened to a content of 1.2% to 1.6% by weight of titanium.
- An alloy of vanadium serves as a carbide or nitride scavenger.
- maraging steels described there are not only suitable for use as spring steels but also as a material for golf club heads if additional cold deformation is used here before curing.
- the present invention can be used to produce maraging steels which are characterized by extremely high Vickers hardness, tensile strength, yield strength and very high Characteristics of alternating bending strengths, storable energies and reciprocal damping.
- the isotropic formability which is in the foreground in WO 01 / 53556A1 is not important in the present invention.
- the object of the present invention is therefore to develop new maraging steels for golf club heads, in particular for
- a maraging steel which is characterized by high flexural fatigue strength, storable energies and reciprocal damping.
- the object is achieved by a Golf Club Head, which at least in part c of a stainless precipitation-hardened maraging steel having a martensite temperature Mg ⁇ 130 ° C, a ferrite Ferr it ⁇ 3%, wherein the maraging steel consists essentially of 6.0 to 9.0% by weight Nickel, 11.0 to 15.0% by weight of chromium, 0.1 to 0.3% by weight of titanium, 0.2 to 0.3% by weight of beryllium, remainder iron, in addition to inevitable impurities, and which has a tensile strength R m > 2000 MPa and has a proof stress R p o, 2 > 1900 MPa .
- FIG. 1 shows a so-called “Schaffler” diagram, in which the alloy area according to the invention is identified. This figure corresponds to FIG. 6 from WO 01/53556 A1 mentioned at the beginning.
- chromium content typically, up to 35% can be replaced by molybdenum and / or tungsten.
- the maraging steel can contain up to 4% by weight of copper, as a result of which the corrosion resistance, which is in itself very good, is further increased.
- up to 50% of the nickel content can be replaced by the more expensive cobalt compared to nickel without affecting the physical and technical properties of the alloy.
- the maraging steel can contain at least one of the elements manganese, silicon or niobium in individual proportions of less than 0.5% by weight.
- the contents of carbon, nitrogen, sulfur, phosphorus, boron, hydrogen or oxygen are adjusted to less than 0.1% by weight. If these proportions are exceeded, it can lead to undesirable carbide, boride or nitride deposits that negatively influence the technical properties of the material.
- the maraging steel according to the invention contains up to 0.1% by weight of cerium or cerium mixed metal as a deoxidation additive.
- the martensite temperature M s which must be above 130 ° C. according to the present invention, is set by equation (1):
- the ferrite content can be adjusted according to equation (2):
- the present alloys are typically produced by casting a melt in a crucible or furnace under vacuum or in a protective gas atmosphere.
- the melting temperatures are around 1500 ° C.
- the cast ingots made from the present alloys are then pre-blocked at a temperature of approximately 1000 ° C. to 1200 ° C. and thermoformed into a blank at 100 ° C. ⁇ T 1 11 1150 ° C.
- the low Hot rolling temperatures are selected in order to minimize the edge zones depleted of free beryllium.
- solution annealing (homogenization) of the blank takes place in a temperature range of 850 ° C. ⁇ T 2 ⁇ 1100 ° C., depending on the choice of the annealing time.
- the blank After the blank has been cooled to a temperature of T 3 ⁇ 300 ° C., the blank is ground at a temperature which corresponds approximately to room temperature in order to completely remove the edge zone which is depleted of free beryllium.
- the blank is then cold worked to a degree of cold deformation greater than or equal to 60%, in particular forged or extruded or rolled.
- the blank is then subjected to a heat treatment at 400 ° C. ⁇ T 4 ⁇ 550 ° C. for a period of between one hour and 10 hours.
- the maraging steels according to the invention have tensile strengths R m > 2400 MPa. With a degree of cold deformation of less than 60%, tensile strengths of 2000 ⁇ R m ⁇ 2400 MPa are achieved.
- the present invention makes it possible to provide materials for golf club heads, in particular for their striking plates, which, in addition to the enormous tensile strengths, also have Vickers hardnesses HV> 700 or in special cases> 800. Furthermore, yield strengths Rpo, 2 > 210 ° MPa can be achieved at the same time. In the case of the special second heat treatment, proof stresses R o, 2> 2600 MPa can be achieved.
- the maraging steels according to the invention are distinguished in the absence of inner and outer notches by alternating bending strengths ⁇ j ;) W ( with typical 10 3 load changes) of approximately 1350 MPa or in special cases of 1550 MPa.
- the maraging steels according to the invention also have an extremely high storable energy Rm 2 / E modulus of approximately 30 MPa, in special cases 40 MPa, which is particularly advantageous for use as a striking plate, because of the high strength.
- the materials according to the invention again have very low damping values, which is due to the high strength and the very fine martensitic structure, in which the grains are in the range of approximately 1 ⁇ m.
- the materials according to the invention can be soldered as well as brazed.
- the maraging steels according to the invention can be welded.
- the weldability is particularly advantageous since the striking plates made of the alloys according to the invention can be firmly and permanently connected to the golf club head hulls.
- the striking plates can be welded with almost all other materials known from golf clubs, for example other stainless steels.
