Abstract
An SGS trantalum material is a microalloyed material doped with rare-earth elements, and is preparedf rom tantalum powder through doping rare-earth elements, high-temp. sintering or electronic bombarding, forging, cogging blooming, finish rolling, washing and annealing to obtain Ta-plate. Its products are made up of the said Ta-plate through blanking punching and stretching, drilling, welding, rivetting and turning. Its advantages are high-temp. performance and long service life.
Description
The present invention relates to rare metal and alloy field thereof, particularly a kind of SGS (Stable GrainSize) tantalum material, Ta product and production method thereof, more particularly, relate to that to be used under the condition of high temperature grain growth slow, weave construction is stable, keep the good mechanical performance, tantalum material, Ta product and the production method thereof of long service life.
Tantalum is a rare metal, has fusing point height, corrosion-resistant, plasticity good, chemically reactive is high characteristics.Based on the above characteristics of tantalum, tantalum material and Ta product needing under the high temperature to be usually used in the occasion of good strength and stiffness, as the high temperature starting material in the heater element in the High Temperature Furnaces Heating Apparatus, heat insulating member, charging vessel, strut member and other stoves.With the various goods that common tantalum material is produced, as crucible, well heater, thermoscreen etc., work-ing life is shorter.This is because tantalum is a reactive metal; every oxygen; carbon; nitrogen; so-called interstitial element such as hydrogen; under the effect of certain temperature and time, all can enter in the tantalum material and become impurity; common tantalum is when being higher than its above life-time service of recrystallization temperature; because some elemental gas of the purity finite sum material handling of inert gas heat absorption back are overflowed in the body of heater; add the tantalum material air-breathing characteristic of being heated; shielding gas impurity and material escaping gas impurity are attracted to the tantalum accessory surface in the stove in the stove; be adsorbed on the oxygen on the tantalum accessory surface in the stove; hydrogen is converted into the oxygen of ADSORPTION STATE; hydrogen atom is dissolved among the tantalum crystal; the tantalum crystal carries the oxygen that accumulates over a long period under the high-temperature effect for a long time; nitrogen-atoms and the tantalum lattice is widened; volumetric expansion; grain hardening; the oxygen in the crystal boundary meanwhile; nitrogen and oxide compound; nitride is under the combined action of long-time high-temperature lower edge crystal boundary migration; make the crystal boundary inanition; crystal expands; the crystal grain embrittlement is loose etc.; stove tantalum accessory is scrapped by the scaling loss embrittlement; this is to resource scarcity; expensive tantalum material and goods thereof are totally unfavorable; Rodney Stark (H.C.STARCK) company of Germany offers the SGS Ta product that NRC company is used for stove tantalum accessory; adopt the vacuum arc melting method to produce SGS tantalum ingot; utilize this tantalum ingot to be processed into Ta product again; the tantalum crucible life-span is 3000 heats/1650 ℃ 2 hours, and tantalum piece well heater and tantalum thermoscreen work-ing life were greater than 1500 heats/1650 ℃ 2 hours.But tantalum is a refractory metal, and it is higher to establishing matching requirements to utilize arc melting method to produce SGS tantalum ingot, and the production cost height is unfavorable for large-scale industrial production.
The object of the present invention is to provide a kind of SGS tantalum material, Ta product and production method thereof, tantalum material of Sheng Chaning and Ta product thereof at high temperature not only keep the good mechanical performance in this way, and at high temperature grain growth is slow, keeps stable crystalline structure, and be enhanced about more than once work-ing life.
The object of the present invention is achieved like this:
A kind of SGS tantalum material, it is to be added with the thulium of 50～150PPM and the microalloying material that obtains through high temperature sintering or electron-bombardment and thermal treatment in the composition;

A kind of production method of SGS tantalum material may further comprise the steps:
(1) by doped rare earth element in the tantalum powder, high temperature sintering or the electron-bombardment tantalum ingot that obtains mixing;
The doping tantalum ingot that (2) will obtain is through forging and pressing cogging, breaking down, finish rolling, cleaning, lehr attendant
Preface makes SGS tantalum sheet material;
The purposes of above-mentioned SGS tantalum sheet material is a raw material with SGS tantalum material, makes the SGS Ta product by blanking, punching stretch, boring, welding, riveted joint, turning manufacturing procedure;
Above-mentioned SGS Ta product is a vacuum high temperature furnace tantalum accessory;
Above-mentioned vacuum high temperature furnace comprises tantalum crucible, tantalum well heater, tantalum thermoscreen, tantalum bracing frame etc. with the tantalum accessory.
SGS tantalum plate and the Ta product produced with method of the present invention not only have the favorable mechanical performance at high temperature, and high temperature life has obtained improving greatly, as having reached 3000 heats/1650 in work-ing life of tantalum crucible ℃ 2 hours, tantalum well heater and tantalum thermoscreen reach 1500 heats/1650 work-ing life ℃ 2 hours.
