Title:
ALUMINUM-SCANDIUM ALLOY TARGET MATERIAL WITH HIGH SCANDIUM CONTENT AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/051514
Kind Code:
A1
Abstract:
Provided in the present application is a manufacturing method for an aluminum-scandium alloy target material with a high scandium content. By mixing an Sc powder and an intermetallic compound Al3Sc powder, the powder sintering temperature can be increased to 1000-1300ºC due to the relatively high melting point of both Sc (1541ºC) and Al3Sc (1320ºC); furthermore, the good bonding toughness of elemental Sc can avoid the cracking of a highly-dense aluminum-scandium alloy target material, such that the density of an AlSc target material is improved; and moreover, since the intermetallic compound Al3Sc powder is directly added, the alloy phase can be distributed more uniformly and dispersedly.
