Embodiment
Because characteristics such as its high strength, low elastic modulus so, low density and corrosion stability are good, Ti-6Al-4V has replaced traditional kaki and 17-4PH Steel Alloy since generation nineteen ninety, use seat (crown) and the scope of attack (face) on golf club widely, in order to enlarge happy district, suppress gross weight and to increase the MOI value, the bulb size increases to 450cc from 200cc originally, the part of seat (crown) is also more done thinner, and the design of counterweight also causes external form also more and more complicated.U.S.Pat.No.2003-0036442 also is reduced to the thickness of seat (crown) below the 0.8mm, and degree of difficulty is quite high for the Ti-6Al-4V casting.Result according to U.S.Pat.No.4830823, the aluminium of interpolation 1.5 to 4wt% and 1 to 3wt% vanadium (being typically Ti-3Al-2.5V), significantly increased the castibility of pure titanium, however intensity but have only Ti-6Al-4V 60% (Ti-3Al-2.5V is 621MPa; Ti-6Al-4V is 1100MPa), can not satisfy the use of golf club.Some famous brand names such as Callaway in recent years, the golf club that release successively such as Taylormade is new, mass part is made of beta-titanium alloy, as Ti-4.5Al-3V-2Fe-2Mo, Ti-15V-3Zr-3Al-3Sn etc., reason is that these beta alloy have high strength, low elastic modulus so, and the most direct benefit more provides the planner to have bigger space to carry out best mechanics design except promoting anti-sending out the coefficient.Yet these alloys are because the interpolation of high alloy element, and are not suitable for casting, so the alloy of development of new high strength easy casting is instant thing.
In this case contriver research in recent years, aspect castibility, propose significantly to have promoted the castibility of pure titanium or titanium alloy in recent years by the interpolation of bismuth metal, the bismuth that adds 1wt% has increased by 34.4% compared to pure titanium casting and (has obtained United States Patent (USP), U.S.Pat.No.6409852, its content is merged in this case in the reference mode).The interpolation of bismuth has also significantly promoted the castibility of titanium alloy, for example Ti-6Al-7Nb-1Bi, Ti-6Al-4V-1Bi, Ti-7.5Mo-1Bi and Ti-15Mo-1Bi castibility are all just good for the Ti-6Al-4V of golf club casting use than present, the visible this case contriver's of these results U.S. patent application case publication number 2004-0136859 (its content is merged in this case in the reference mode).This case contriver is also having up-to-date result of study aspect the alloy designs of titanium alloy in addition, in the research in recent years, discovery has α, and " the Ti-Mo alloy of phase (typical composition is Ti-7.5Mo) represents very outstanding intensity; modulus of elasticity and ductile combination; the ratio of its intensity/modulus of elasticity (being one of leading indicator of mechanical properties) is apparently higher than traditional Ti-6Al-4V and nearly all titanium alloy of having developed; be the latest model titanium alloy (obtained United States Patent (USP); U.S.Pat.No.6409852, its content is merged in this case in the reference mode) of a tool potentiality to be exploited.Except having the high strength low elastic modulus so, has good cold-workability at Ti-15Mo-1Bi aspect the beta-titanium alloy, directly about 90% (in the U.S. Patent application) of cold working.
The present invention has disclosed and has utilized the good bismuth-containing titanium alloy of castibility to carry out the golf club casting, and carry out mechanical properties, instead send out the assessment of coefficient and weather resistance (durability) character, to develop the high strength of more novel high strength easy casting bismuth-containing titanium alloy-particularly, low elastic modulus so titanium alloy-to replace the not good conventional titanium alloy of castibility in the past.
Following table 1 is listed the test result of the castibility of pure titanium that U.S. patent application case publication number 2004-0136859 disclosed and multiple titanium alloy

The present invention of The above results proof takes the lead in using the bismuth-containing titanium alloy to cast golf club can overcome the problem that is easy to generate defective that known skill is cast golf club with titanium alloy, and the golf club that the bismuth-containing titanium alloy is cast is still possessed the high strength of titanium alloy and the excellent mechanical properties of low elastic modulus so.
This case contriver carries out cold rolling and fatigue test with Ti-15Mo-1Bi (15 weight % molybdenums and 1 weight % bismuth, all the other are titanium) alloy.Bismuth with commercial pure titanium (c.p.Ti) bar, 99.95% molybdenum bar and 99.5% uses casting system (Castmatic, Iwatani company, Japan) to prepare this alloy in a commercial electric arc melting vacuum pressure type.At first bled and the argon flushing in the fusion cabin.During fusion, keep 1.8kgf/cm
2Argon pressure.With the c.p.Ti bar of proper amt, molybdenum and bismuth are with the intracardiac tungsten electrode fusion of the copper stove of a U type.Melted ingot is melted three times to improve chemical uniformity.
Use a graphite mo(u)ld to prepare 5.0mm thickness, the Ti-15Mo-1Bi sample that 13mm width and 70mm are long.The sample that shifts out from this mould is with the water quenching, and carries out surfacing before cold rolling.It is cold rolling to use 100 tons of roll squeezers (VF PCAK-P1, Toshiba company, Japan) at room temperature to carry out, and wherein this sample carries out roll-in for several times by the slit between two running rollers, and has the different distortion amount by adjusting the slit between two running rollers.
As the minimizing 1.5mm of order with thickness, 0.9mm, 0.9mm, 0.3mm and 0.3mm carries out this when cold rolling (always being reduced to 78% of thickness), and is that all samples of Ti-15Mo-1Bi all can be cold-rolled to the total minimizing of final thickness 78% and do not rupture or be presented at any slight crack on sample surfaces or the limit.But carry out when cold rolling with the Ti-15Mo alloy, then finding has slight crack or surface to go up the distortion ribbon that shows on the limit of Ti-15Mo sample, perhaps even ruptured when cold rolling.As seen but bismuth mixes the cold rolling workability that can promote the Ti-15Mo alloy significantly.
The sample that aforementioned Ti-15Mo-1Bi is cold-rolled to the total minimizing of final thickness 78% carries out 900 ℃, 1 minute thermal treatment.Use a servo-hydraulic test machine (EHF-EG, Shimadzu company, Tokyo, Japan) to carry out fatigue test, wherein sample is the flat board that 40mm is long, 5mm is wide and 1.5mm is thick.This flat board carries out fatigue-bending test with the condition of sine wave, frequency 4Hz and strain ratio R=0.1 in room temperature and air.Have four kinds in various degree the flat samples of roughness be prepared: (1) uses the 60# sandpaper to obtain surface roughness, Ra=0.9～1.1 μ m (the Ra value measures according to ISO 4287:2000 method); (2) use the 1000# sandpaper to obtain surface roughness, Ra=0.1～0.2 μ m; (3) use the 1000# sandpaper to reach in regular turn with 1 μ m, 0.3 μ m and 0.05 μ m aluminum oxide mechanical polishing obtain surface roughness, Ra＜0.1 μ m; (4) use the 1500# sandpaper to reach then to contain 5 volume %HF, 15 volume %HNO
3Carry out chemical rightenning with the aqueous solution of 80 volume % water and obtain surface roughness, Ra＜0.1 μ m.From the tired test result of above-mentioned flat samples, this case contriver finds the critical surfaceness that depends on sample of fatigue lifetime/fatigue resistance.The sample of the surface roughness Ra=0.9 of aforementioned (1)～1.1 μ m, its fatigue lifetime about 4 * 10
3To 10
4Cycle.The sample of the surface roughness Ra=0.1 of aforementioned (2)～0.2 μ m, its fatigue lifetime about 10
4To 6 * 10
4Cycle.The sample of the surface roughness Ra＜0.1 μ m of very unexpected aforementioned (3) and (4) has the dramatic fatigue lifetime that promotes, and six wherein tested samples have four samples 10
6All after dates, tired yet.Easy speech, the Ti-15Mo-1Bi sample of surface roughness Ra＞0.1 μ m can emit the metal risk of tired failure ahead of time.
