Abstract

The invention relates to the technical field of alloy production, particularly a powder alloy and a production technique thereof. The powder alloy comprises 0.04-0.09% of C, 12-14% of Cr, 7-9% of Co, 3.3-3.7% of W, 3.3-3.7% of Mo, 2.3-3.7% of Al, 3.3-2.7% of Ti, 3.3-3.7% of Nb, 0.006-0.015% of B, 0.03-0.07% of Zr and the balance of Ni. The powder alloy is a highly-alloyed r'-phase precipitation-reinforced nickel-base high-temperature alloy, wherein the r' volume content is 50-55%, and the r' formed element content (atomic) is 28%. The powder alloy is a turbine disk material at the highest strength level under the operating condition of 650 DEG C at present. The powder alloy not only can be used for high/low-pressure turbine disks, but also can be used for gas compressor disks, turbine shafts, turbine baffle rings, high-temperature sealing parts and other high-temperature parts. The powder alloy is prepared by a plasma rotating electrode powder manufacturing apparatus, and the powder quality is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of alloy production, in particular to a powder alloy and a production process thereof. Background technique [0002] Precision alloys are metal materials with special physical properties, which are used in the manufacture of electronics, electrical devices, precision instruments and meters, etc. It is an indispensable material in the electrical industry, electronics industry, precision instrument industry and automatic control systems. Precision alloy strips cannot be used for high temperature parts such as compressor discs, turbine shafts, turbine retaining rings, high temperature seals, etc. According to different application requirements, HIP (hot isostatic pressing) direct forming, HIP + die forging can be used for powder superalloys , HIP + isothermal forging and extrusion + isothermal forging and other different process routes. In the absence of large extruders and large isothermal forging machines in...
