Title:
NICKEL ALUMINIDE SERIES SUPERALLOY
Document Type and Number:
Japanese Patent JP2001220635
Kind Code:
A
Abstract:
To impart good mechanical various properties at high temperature- room temperature and good weldability required for a structural material to an Ni3Al series Ni base super heat resistant alloy used as a high temperature structural element.
This Ni base super heat resistant alloy has a composition containing, by weight, 6.0 to 9.0% Al, 2.0 to 15.0% Cr, 0.5 to 3.0% Zr, 0.003% or less B, 3.0% or less Fe, and the balance substantial Ni and containing one or more than two kinds of elements selected from 0.5 to 5% W, 0.3% or less C and 0.003 to 0.03% N at request, and has a metallic structure composed of an Ni3Al series intermetallic compound as the main phase (volume ratio of 70% or more).
