Microstructure Characteristic of Directionally Solidified NTS-09C Alloy

Abstract:

The directionally solidified Nb-Ti-Si-Cr-Al-Ta-Hf-C-B (NTS-09C) superalloys were prepared by HRS method. This alloy with strong orientations of (Nb, Ti)ss and Nb-silicide along the growth direction consists of (Nb,Ti)ss, (Nb,Ti)3Si, Nb5Si3, MC carbide and C14 Laves phases. Not only the morphologies and compositions of various phases have been systemically studied, but also the formation mechanisms have been analyzed and discussed in detail.
