Brittle Materials Design, High Temperature Gas Turbine Material Technology. Volume 4

Abstract

In 1971 Norton obtained an exclusive license to produce Lucas hot pressed silicon nitride in the United States. That process made a high-density, high strength ceramic material with excellent potential for high temperature application, i.e., industrial gas turbine components, available commercially. Project funds were used to develop an engineering property data base to describe Norton HS130/Noralide NC132 silicon nitride and Noralide NC203 silicon carbide. The list includes tensile, flexure, shear, and compressive strengths from room temperature to 2550 F for appropriate directions in anisotropic materials along with elastic/shear moduli and Poisson's ratio. Creep resistance is defined in terms of creep strain and stress rupture life as a function of temperature, time, and environment. Thermal properties were also considered, i.e., thermal expansion, conductivity, and specific heat. Equipment and test procedures are discussed.
