Alloy powder, including following components:: the rare earth unit of P, 0.01-0.5% of Cu, 0.3-2% of Fe, 19.5-20.5% of 77-81%
Element.
Described rare earth element is Ce and Y.
The preparation method of a kind of superhard material products rare earth special regulation water atomization Fe-Cu pre-alloyed powder, including following
Step: successively Fe, Cu, CuP, Rare-Earth Ce and Y are joined in stove, energising fusing refine, take off by the mode adding carbon dust
Oxygen, when adjustment superheat of liquid steel is 150 ~ 200 DEG C, pours in tundish, after molten steel is by bag end leakage eye, by high pressure water attack
Broken, under conditions of being filled with nitrogen protection, it is atomized into powder, the powder vacuum filtration after atomization terminates is dehydrated, and is then charged into doing
Being dried in dry case 6 ~ 10 hours, then reduce with hydrogen nitrogen mixed gas, powder after reduction is crossed screen cloth and sieves, siftage loads
Powder mixing machine is sufficiently mixed.
Described hydrogen nitrogen mixed gas reduction is carried out in step-by-step movement pushes away boat reduction furnace.
The volume ratio that in described hydrogen nitrogen mixed gas, hydrogen accounts for is 75%.
Described hydrogen nitrogen mixed gas reduction temperature is 600-680 DEG C,
Described step-by-step movement pushes away and pushes away boat amount in boat reduction furnace is 5 ~ 10kg/ boat, and fltting speed is 5 ~ 10 minutes/boat.
Described screen cloth is 325 eye mesh screens.
The invention has the beneficial effects as follows: the invention provides a kind of superhard material products rare earth special regulation water atomization Fe-
Cu pre-alloyed powder and preparation method thereof, the present invention uses high-temperature liquid state melting and hydraulic atomized method, production to prepare ultra-fine
Ferrum copper pre-alloyed powder, is internally formed the consistent mechanical mixture of Fe-Cu elementide at powder particle, breaks through in traditional sense
Solid solution alloy concept and form new product line.Based on Fe, it is aided with soft phase Cu, and adds brittlement phase formation element P
And the rare earth element (Ce, Y) of crystal grain thinning, producing preparation two constituent element Fe-Cu basis pre-alloyed powders, price is low, combination property
Good, as universal basic pre-alloyed powder, can preferably meet the performance requirement of the superhard goods of variety classes, element P is permissible
It is internally formed Fe at alloy powder particle3P、Cu2The hard & brittle points such as P, Dispersed precipitate, regulate the fragility abrasion of powder sintered tissue
Performance, the beneficially sharpness of improvement instrument；Rare earth element ce, Y can refine powder grain, improve the cause of powder sintered tissue
Density and bending strength, be conducive to improving the sintering structure hold to diamond.
