21. Instrumented Indentation and Ultrasonic Velocity Techniques for the Evaluation of Creep Cavitation in Silicon Nitride
Published: 1/1/2003
Authors: F Lofaj, Douglas T Smith, Gerald V. Blessing, William E Luecke, Sheldon Martin Wiederhorn
Abstract: Instrumented indentation and ultrasonic wave velocity techniques combined with precise density change measurements and transmission electron microscopy (TEM) were used to investigate the changes of elastic moduli in silicon nitride after tensile defo ...

22. Effect of Temperature, Strain Rate, and Grain Size on the Mechanical Response of Ti^d3^SiC^d2^ in Tension
Published: 4/1/2002
Authors: M Radovic, M W Barsoum, T El-Raghy, Sheldon Martin Wiederhorn, William E Luecke
Abstract: Results of tensile tests at constant cross head displacement rates, relaxation tests and cycling loading-unloading tests indicate that the mechanical response of Ti^d3^SiC^d2^ is a strong function of temperature, strain rate and grain size. Loading ...

23. Creep of Lanthanum Gallate
Published: 3/1/2002
Authors: William E Luecke, T R Armstrong
Abstract: Strontium- and magnesium-doped lanthanum gallate (LSGM) was deliberately prepared to give A-site deficient non-stoichiometry with compositions (La^d0.9^Sr^d0.1^)z(Ga^d0.8^Mg^d0.2^)O^d3-delta^ (z =1.0,0.98, and 0.95). Creep tests in four-point 950 C ...

24. Results of an International Round-Robin for Tensile Creep Rupture of Silicon Nitride
Published: 2/1/2002
Author: William E Luecke
Abstract: Fourteen laboratories participated in an ubterkabiratirt study to establish the within- and between-laboratory repeatability of tensile creep rupture of silicon nitride. In air at 1375 C at 200 Mpa the times to failure ranged over a factor of 50, ...

25. Standards for Reliability Testing of Heavy Vehicle
Published: 10/1/2001
Authors: S Jahanmir, James F Kelly, William E Luecke
Abstract: The objective of this project is to develop international standard test methods for assessing the reliability of ceramic components used in diesel engines and other heavy vehicle propulsion systems. Advanced ceramics such as silicon nitrides offer un ...

27. Comparison of Tensile and Compressive Creep Behavior in Silicon Nitride
Published: 1/1/2000
Authors: K J Yoon, Sheldon Martin Wiederhorn, William E Luecke
Abstract: The creep behavior of most commercial grade of Si^d3^N^d4^ was studied at 1350 and 1400 C. Stresses ranged from 10 to 200 Mpa in tension and from 30 to 300 Mpa in compression. In tension, the creep rate increased linearly with stress at low str ...

28. High-Temperature Properties of Liquid-Phase-Sintered {Alpha}-Sic
Published: 11/1/1999
Authors: R P Jensen, William E Luecke, N P Padture, Sheldon Martin Wiederhorn
Abstract: We have characterized the high-temperature subcritical crack growth and oxidation resistance of a liquid-phase-sintered (LPS) SiC with 20% volume fraction yttrium aluminum garnet (YAG) second phase. Constant stress rate testing in air in the temperat ...

29. A new model for tensile creep of silicon nitride
Published: 10/1/1999
Authors: William E Luecke, Sheldon Martin Wiederhorn
Abstract: The tensile creep rate of most commercial grades of Si3N4 increases strongly with stress. Although the usual power-law functions can represent the creep data, the data often show curvature and systematic variations of slope with temperature and stre ...

30. Tensile Creep and Rupture of Silicon Nitride
Published: 5/1/1999
Authors: Ralph Krause, William E Luecke, J French, B Hockey, Sheldon Martin Wiederhorn
Abstract: We have characterized the tensile creep, rupture lifetime, and cavitation behavior of a commercial, gas-pressure-sintered silicon nitride in the temperature range 1150 to 1400 C and stress range 70 to 400 MPa. Individual creep curves generally sho ...
