MICROSTRUCTURE, CREEP AND FAILURE: A PROGRAM FOR GRADUATE EDUCATION AND RESEARCH IN HIGH TEMPERATURE MATERIALS

Abstract

The paper is a general study of the role of microstructure on the mechanical properties of high temperature materials. Short time tensile and compression tests, fatigue, creep and thermal strain tests are being performed on metals, principally unidirectionally solidified lamellar eutectics, including the NiCr eutectic, and also on ceramics. The solidification characteristics for various growth conditions and the mechanical properties over the temperature range -250 to 850C have been obtained for the Ni-Cr eutectic. The composite strength is analyzed in terms of the rule of mixtures and the interpretation is backed by transmission electron microscopy at all stages.
