Title: Study on precipitates in Ni-Al-Mo-B alloy IC6 with addition of excess amount of yttrium

Abstract

A directionally solidified (DS) alloy IC6 with the chemical composition of Ni-(7.5-8.5)Al-(13.0-15.0)Mo-(0.02-0.1)Bwt% has been recently developed in BIAM as a high-temperature structural material used for advanced jet-engine blades and vanes operating in the temperature range of 1,050--1,150 C. The alloy not only has high yield strength and fairly good ductility from room temperature to 1,100 C, but also has high creep resistance in the temperature range 760--1,100 C. Alloy IC6 has low density (7.9 g/cm{sup 3}), low cost, high melting temperature (1,300 C). Its high temperature oxidation resistance is substantially improved by adding proper amounts of yttrium but decreases with addition of excess amount of yttrium. The purpose of this paper is to investigate the precipitates in alloy IC6 due to the presence of yttrium.
