The spherical hydrogenation titanium powder for sintering alloy where the powder granularity which is obtained with production manner of the spherical hydrogenation titanium powder

摘要

PROBLEM TO BE SOLVED: To provide spherical titanium hydride powder for a sintered alloy which has high powder fluidity, high apparent density, and high packing properties into a die even without undergoing pulverization treatment by the application of mechanical impact and striking, and a method for producing a sintered alloy by the spherical titanium hydride powder.;SOLUTION: The spherical titanium hydride powder for a sintered alloy having a powder grain size of ≤150 μm is obtained by hydrogenizing spherical titanium powder, and has excellent powder fluidity and packing properties. The spherical titanium hydride powder having a powder grain size of ≤150 μm is mixed with molybdenum or tungsten powder produced as the fine powder having an extremely small powder grain size, and the powdery mixture is sintered to produce a titanium-molybdenum or titanium-tungsten sintered alloy.;COPYRIGHT: (C)2002,JPO
