Description
Technical field
The present invention relates to a kind of titanium materials technology field more particularly to a kind of high-performance cutter titanium alloys.
Background technique
Currently, substantially falling will be using the system of titanium alloy progress cutter in some special industries, especially military industry
Make, cutter hardness HRC value made by existing titanium alloy is generally less than 46, the hardness HRC value of cutter for same in some operations
It is greater than 50, the cutter that existing titanium alloy is produced in some environments so just can not meet requirement, Chinese invention patent
A kind of titanium alloy and preparation method thereof for making cutter is disclosed in CN102851542A, although this method proposes HRC value
Up to 55-57, but 4% vanadium metal is added, lead to holding at high price for titanium alloy.
Therefore, it is necessary to research and develop a kind of high-performance cutter titanium alloy, both cost can be reduced, simultaneously with substituted metal vanadium
Also it can break through the relatively low technical bottleneck of cutter hardness HRC value.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of high-performance cutter titanium alloys.
Technical scheme is as follows：
