Embodiment 1

[0012] Mix Ti powder with a certain particle size distribution and added powder containing Al, V, Fe and Mo elements. The particle size ratio of titanium powder is: -100 mesh ~ +150 mesh titanium powder accounts for 85wt%, -325 mesh Titanium powder accounts for 15wt%; in the added powder, the proportions of each element in the mixed powder are: Al element accounts for 6wt%, V element accounts for 4wt%, Fe element accounts for 0wt%, and Mo element accounts for 0wt%. After mixing evenly, the powder is formed by bidirectional molding with a pressing pressure of 500 MPa. In the subsequent multi-stage sintering process, the shaped body was first held at a low temperature stage of 120 °C for 30 minutes, then heated to 850 °C at a heating rate of 10 °C / min, and then heated to 1260 °C at a heating rate of 2 °C / min ℃, and keep warm for 5 hours. The sintering atmosphere is vacuum, and the vacuum degree is controlled at 1×10 -2 ~1×10 -3 Pa. After the heat preservation is over, it is ...

Embodiment 2

[0014] Mix the Ti powder with a certain particle size distribution and the added powder containing Al, V, Fe and Mo elements. The particle size ratio of the titanium powder is: -150 mesh ~ +250 mesh titanium powder accounts for 75wt%, -250 ~ +400 mesh titanium powder accounted for 25wt%; in the added powder, the proportions of each element in the mixed powder were: Al element accounted for 4.5wt%, V element accounted for 3wt%, Fe element accounted for 2wt%, and Mo element accounted for 1wt%. After mixing evenly, the powder is formed by unidirectional molding with a pressing pressure of 700 MPa. In the subsequent multi-stage sintering process, the shaped body was first held at a low temperature stage of 100 °C for 1 hour, then heated to 900 °C at a heating rate of 15 °C / min, and then heated to 1320 °C at a heating rate of 4 °C / min ℃, and keep warm for 4 hours. The sintering atmosphere is protected by argon. After the heat preservation is over, it is quenched immediately by oi...

Embodiment 3

[0016] Mix Ti powder with a certain particle size distribution and added powder containing Al, V, Fe and Mo elements. The particle size ratio of titanium powder is: -100 mesh ~ +200 mesh titanium powder accounts for 70wt%, -250 mesh Titanium powder accounts for 30wt%; in the added powder, the proportions of each element in the mixed powder are: Al element accounts for 3wt%, V element accounts for 2wt%, Fe element accounts for 0.5wt%, and Mo element accounts for 0.5wt%. After mixing evenly, powder molding is carried out by means of bidirectional molding with a floating female mold with a pressing pressure of 400 MPa. In the subsequent multi-stage sintering process, the formed body was first held at a low temperature stage of 90 °C for 2 hours, then heated to 800 °C at a heating rate of 20 °C / min, and then heated to 1200 °C at a heating rate of 3 °C / min ℃, and keep warm for 7 hours. The sintering atmosphere is vacuum, and the vacuum degree is controlled at 1×10 -2 ~1×10 -3 Pa...

Abstract

A metallurgy method for producing titanium alloy powder for producing golf bar heads is disclosed, pertaining to preparing method of titanium alloy for golf bar heads. The method uses Ti powder and additive powder containing Al, V, Fe, and Mo elements as raw materials, mixes the Ti powder with a certain granularity proportion and the additive powder with a certain component range evenly, prepares slice blank by using a die forming mode, uses a multi-stage heating technique giving priority to middle-low temperature quick heating and high temperature slow heating during sinter process, performs quenching immediately after the heating process is completed, thereby prepares the Ti alloy sintering blank, and the titanium alloy material for producing golf bar head is finally produced by forge work and subsequent anneal process. Since the powder metallurgy technique has the characteristics of near net shape and easily control components, alloying is realized easily. At the same time, the high-usage of raw material is provided, the raw material cost and processing cost are saved, and the production energy consumption is reduced greatly. The method is suitable for producing titanium alloy material for producing golf bar heads.

Description

Technical field: [0001] The invention relates to a method for preparing a titanium alloy for a golf club head, in particular to a powder metallurgy method for preparing a titanium alloy for a golf club head. Background technique: [0002] At present, titanium alloy materials for golf club heads are usually prepared by a series of processes such as casting and subsequent multiple machining, thermal processing and heat treatment. This method has the disadvantages of complex process, high energy consumption, low utilization rate of raw materials, and low yield. Meanwhile, the titanium alloy itself is difficult to process, which results in high cost of the titanium alloy golf club head. Powder metallurgy is used to prepare titanium alloy materials for golf club heads. At present, there is no relevant public report in China. Invention content: [0003] The present invention aims to introduce powder metallurgy titanium alloy into golf club head materials, and provides a method ...
