Abstract

PURPOSE: To enable the alloy powder consisting of Mo-W solid solution and having a specified grain size to be utilized as the raw material for powder metallurgy.
CONSTITUTION: This alloy powder is a solid solution consisting of Mo and W and the quantity of W in Mo is 5W95 atom weight %. Further, the grain size of this alloy powder is below 20μ. For example, 54 g of Mo powder and 46 g of W powder are dissolved in aqueous ammonia of 28%. When these ammonium salts are neutralized gradually with hydrochloric acid, a needle crystal is deposited. By sintering the mixture of these coprecipitated WO3 and MoO3 at 800°C in the air and reducing it at 1000°C in the stream of H2 gas, the raw material powder having grain size of 2μ is obtained.
