Abstract:
One aspect is a method for producing an alloy, whereby the alloy consists of a first metal, a second metal, a third metal, and a fourth metal, and the first metal, the second metal, the third metal, and the fourth metal are selected from the group consisting of the metals, niobium, zirconium, tantalum tungsten. The method includes the steps of grinding the first metal to form a first metal powder and grinding the second metal to form a second metal powder; mixing the first metal powder and the second metal powder to form a first blended powder; generating a first blended body from the blended powder by a powder metallurgical route; and generating the alloy by melting the first blended body and the remaining metals by a melt metallurgical route.
