Test Facility for Material Erosion at High Temperature

1979
One of the next steps in experimental material erosion investigation is the testing at high temperatures comparable to those found inside a jet engine. Described in this paper is the design of the high-temperature erosion facility at the University of Cincinnati.

Optical properties of composite materials at high temperatures

Solid State Communications, 1997
The optical properties of composite materials are studied theoretically as a function of temperature via a phenomenological model for temperatures up to the melting points of the materials. Both the Maxwell-Garnett and Bruggeman models are considered and the temperature variation of the optical constants of the metallic particles is obtained with an ...

Fracture behaviour of ceramic materials at high temperatures

Metal Science, 1981
AbstractFracture toughness K 1C and subcritical crack extension were measured as functions of temperature, loading rate, environment (air, vacuum 2.10−5 mbar) and microstructure. The materials were hot-pressed SiC with a brittle B4C phase and Si infiltrated SiC, denoted SiC(HP) and SiC(IF) respectively.

Structural Reliability of Brittle Materials at High Temperatures.

1984
Abstract : Work during the past year was conducted on yttria-doped hot-pressed silicon nitride, alpha-silicon carbide, and a glass-bonded aluminum oxide. The first two materials were selected for study because of their potential for high temperature structural application, whereas the latter material was selected as a model material to investigate the ...

Thermal expansion of ionic materials at high temperatures

Journal of Applied Physics, 2007
A simple and straightforward method for evaluating and predicting the high temperature volume thermal expansion of ionic materials is developed based on the approximations that at high temperature the temperature derivative of the work done by thermal pressure approaches a constant and the isothermal bulk modulus is linearly dependent on temperature ...

Fatigue of High-Temperature Materials at Ultrasonic Frequencies

1982
The applicability of ultrasonic fatigue testing at 20 kHz for the determination of fatigue properties is discussed. Fatigue crack growth rates as well as S/N curves were determined at very high numbers of cycles at different temperatures and different mean stresses for some high-temperature alloys.
