Title:
FE-SI-B-NB-BASED TARGET
Document Type and Number:
WIPO Patent Application WO/2021/039712
Kind Code:
A1
Abstract:
Provided is an Fe-Si-B-Nb-based target, wherein in the machining of the target, wear or breakage of cutting tool tips, the occurrence of cracking or chipping in the body of the target, and the occurrence of unevenness on the surface of the target can be suppressed. The Fe-Si-B-Nb-based target has a compositional formula represented by Fe100-X-Y-Z-aSiXBYNbZMa in terms of atomic ratio, where 15≤X＋Y≤35, 0.3≤X/Y≤2.0, 1≤Z≤20, 0＜a≤20, and M is at least one element selected from the group consisting of Al, Ti, V, Cr, Mn, Cu, Zr, Mo, W, and C, with the remainder comprising inevitable impurities, and has an average Vickers hardness value of 300-1100 HV as measured at 5 measurement points. The Vickers hardness is preferably in the range of 500-1000 HV.
