Title:
FE-SI-B-NB-BASED TARGET
Document Type and Number:
WIPO Patent Application WO/2021/039710
Kind Code:
A1
Abstract:
Provided is an Fe-Si-B-Nb-based target which is such that abrasion and damage of the tip of a cutting tool, the occurrence of cracking and chipping of the target body, and formation of bumps and recesses on the target surface can be suppressed during machining of the target. The Fe-Si-B-Nb-based target has a composition formula, in terms of atomic ratio, expressed by Fe100-X-Y-ZSiXBYNbZ, wherein 15 ≤ X + Y ≤ 35, 0.3 ≤ X/Y ≤ 2.0, 1 ≤ Z ≤ 20 and the balance inevitable impurities, and has an average Vickers hardness value of 200 to 1,100 HV as measured at five measurement points. The Vickers hardness is preferably in the range of 500 to 1,000 HV.
