Abstract
The invention discloses a high temperature-resistant tungsten alloy material, and belongs to the field of refractory metal materials. The high temperature-resistant tungsten alloy material is characterized by comprising 0.02-0.8% of ZrO2 by mass and the balance of metal tungsten. The high temperature-resistant tungsten alloy material is prepared by directly doping zirconium oxide into tungsten metal powder, or doping zirconium-containing metal salt into tungstate or the tungsten metal powder. Through addition of a dispersed and strengthened high temperature-resistant steady phase ZrO2, dislocating pinning is performed in a high-temperature environment so as to improve the thermal creep resistance of the material, so that the tungsten alloy material system provided by the invention has high heat resistance and can be applied to a heating component or a supporting component in the high-temperature environment; the high temperature-resistant tungsten alloy material has the characteristics of long working life, easiness in preparation and the like, is suitable for industrial production and has a wide application prospect.
Description
Technical field
The invention belongs to refractory metal material field, being specifically related to one can resistant to elevated temperatures tungsten alloy material.
Background technology
The superior resources of Wu Shi China, reserves and the consumption of China surely occupy first place in the world, but the high-end product of the high added value of tungsten product but monopolize by offshore company, particularly be applied to the heating element of tungsten of hot environment, strut member etc., main dependence import, the product of domestic imitation is because of poor heat stability, yielding, life-span is short, applies limited.Tungsten industry product unreasonable structure, and China's tungsten resource great power status is not inconsistent.With the development of modern industry, for various high-end sintering oven, electron source, the performance of ion source contour new installation device proposes more strict requirement, and heating element of tungsten and tungsten strut member are as the key components and parts of this kind equipment, performance quality directly affects the application of device, the mode that heating element of tungsten lost efficacy mostly is structural distortion, thus cause the furnace temperature temperature difference to increase, quality product declines, thus needing the heating element that more renews or new High Temperature Furnaces Heating Apparatus. the application's patent is namely by adding high-temperature stable phase, prepare a kind of new high-temperature heat-resistance tungsten alloy material, thus improve heating element of tungsten or support component performance, make it have longer work-ing life.
Summary of the invention
The present invention mainly proposes a kind of high temperature resistant tungsten alloy material, it is characterized in that:
1 material composition contains the ZrO that mass percent is 0.02%-0.8%
2, surplus is tungsten.
2 zirconium whites can directly adulterate by tungsten metal-powder, and metallic salt also can be adopted as zirconium nitrate, and zirconium acetate etc. adulterate with tungstates or tungsten metal-powder.
The powder of 3 uniform doping is prepared into a material or band through conventional tungsten material preparation technology processing.
Feature of the present invention:
Technical thought of the present invention is the high-temperature stable phase ZrO by adding dispersion-strengthened
2, thus make to carry out pinning to dislocation in hot environment, thus improving the heat creep resistance energy of material, tungsten alloy material system therefore proposed by the invention has resistance toheat better, may be used for the heater part in hot environment or strut member.There is long working life, the features such as easy preparation.Be suitable for industrial production, have a extensive future.
