TL;DR: In this paper, a single crystal nickel-base superalloy having very fine gamma prime after heat treatment in a temperature range permitting total gamma prime solutioning without incipient melting was presented.

TL;DR: In this paper, a team approach has been used to develop a family of two nickel-base single crystal alloys (CMSX-4® containing 3 percent Re and CMSX®-10 containing 6 percent Re) and a directionally solidified, columnar grain nickel base alloy (CM 186 LC® containing three percent Re), for a variety of turbine engine applications.

TL;DR: A team approach involving a turbine engine company (Rolls-Royce), its single-crystal casting facilities, and a superalloy developer and ingot manufacturer (Cannon-Muskegon), utilizing the concepts of simultaneous engineering, has been used to develop CMSX-4 alloy successfully for turbine blade applications as discussed by the authors.

TL;DR: In this article, a nickel base superalloy was proposed for the making of castings which consist of a single crystal, intended for use under extreme conditions of high temperature and stress.

TL;DR: In this paper, a nickel base superalloy for columnar grain, directional solidification which contains Re for strength and creep resistance, and substantially eliminates the use of Zr and minimizes Si to prevent DS grain boundary cracking is presented.
