DEVELOPMENT OF A NICKEL BASE ALLOY SHEET FOR HIGH TEMPERATURE APPLICATION
Abstract
Effort was directed to develop 15 to 30 mil nickel alloy sheet with 50,000 psi tensile strength at 1900 F, good corrosion (oxidation) resistance, and good ductility. This objective was essentially attained by developing a new process of directly rolling thin cast slabs of nickel base alloy into sheet on a specially de signed rigid rolling mill. Two pre-existing nickel base casting alloys and a series of ex perimental compositions obtained by modifying the two starting alloys were initially investigated in the cast condition in this program. The two starting alloy compositions were Inco 713c and the TaZ8 alloy. Of the new experimental compositions, TaZ8 alloy and No. 429 alloy have 1900 F tensile strengths exceeding 50,000 psi at 1900 F in the as cast condition. Inco 713c has a tensile strength of about 40,000 psi in the as cast condition. Procedures were developed on the rigid mill for hot rolling both Inco 713c and TaZ8 alloy into 15 to 30 mil sheet. Heat treatment procedures were developed for both alloys which enabled them to meet contract target strength properties.
