Title: Superalloys with improved weldability for high temperature applications

Abstract

A cast nickel-base superalloy component (10) is made having a composition containing small amounts of both boron and zirconium which are effective in combination to provide increased weldability, where such alloy is adapted for welding by weld (18) to a second superalloy piece, where the two pieces are firmly bonded together and have a Sigmajig transverse stress value (16) greater than 137.9 million Newtons per square meter.
