Title:
チタン−アルミニウム合金部品の製造方法
Document Type and Number:
Japanese Patent JP6445542
Kind Code:
B2
Abstract:
A method manufactures a metal alloy part by spark plasma sintering. The method includes the simultaneous application, inside a die, of a uniaxial pressure and of an electric current to a powder component material that has the following composition: 42 to 49% aluminum, 0.05 to 1.5% boron, at least 0.2% of at least one element selected from tungsten, rhenium and zirconium, optionally 0 to 5% of one or more elements selected from chromium, niobium, molybdenum, silicon and carbon, the balance being titanium and the total of the elements without aluminum and titanium being between 0.25 and 12%.
