1) presoma is prepared：Ni, Nb, Ti, Hf metal are subjected to configuration raw material according to atomic ratio, are placed in crucible for smelting furnace in argon It is heated to melting under gas shielded, melt is then filled into the molten metal packet in jet deposition machine, while being 10 μm by partial size CaCO3It is filled into solids fluidized conveyer；The high pressure of 2~3MPa is passed through into molten metal packet and solids fluidized conveyer respectively Helium is by Ni60Nb20Ti12.5Hf7.5Molten metal and CaCO3The synchronous atomization of particle forms the drop of solid-liquid mixing, in spray chamber lower end Cooler acts on lower drop and quickly solidifies, and is deposited on substrate and obtains granular precursor, 50~100 μm of particle size, deposition away from From 800~1000mm.
2) substrate is prepared：Al, Cu, Mn, Mg metal block are carried out to be added to crucible for smelting with substrate material is made by mass fraction Furnace fusing, obtains aluminium alloy liquid；
3) slab is prepared：The granular precursor that will be obtained in step 1), ultrasonic vibration, which is sufficiently stirred, is filled into jet deposition equipment Solid particle fluidisation conveyer in；The aluminium alloy liquid that step 2) obtains is injected into molten metal packet；To conveyer and gold Belong to liquid packet while being passed through air pressure and be 0.7~0.85Mpa argon gas for aluminum alloy melt and presoma while being atomized, is deposited on substrate and obtains Obtain slab；
4) extrusion forming：The slab that step 3) obtains is put into heat extruder and is preheated to 450~500 DEG C, after keeping the temperature 30min, It is 520 DEG C in temperature, extrusion ratio is 3~5, and extrusion speed is hot extrusion molding under conditions of 1~3mm/s, obtains extruding tubing；
5) solid solution, ageing treatment：The extruding tubing that step 4) is obtained carries out first order solution treatment, solid solubility temperature 470 ± 5 DEG C, soaking time 2h；Second level solution treatment is carried out again, and 490 ± 5 DEG C of solid solubility temperature, soaking time 1h, water cooling (room temperature) turns Shift time≤12s；Tubing progress artificial aging processing after the solution treatment of the second level, 190 ± 5 DEG C of aging temp, soaking time 12h。
6. composite material according to claim 1-4 is preparing the application in drilling rod.
