Assessment of viscoelastic crack bridging toughening in refractory materials
(Elsevier Sci Ltd, Oxford, 2008)
Viscoelastic bridges can be formed in refractory ceramics while cooling from high temperatures. Such bridges can shield crack tips, thus reducing the effective crack tip stress intensity factors leading to higher resistance ...
A fracture mechanics approach to thermal shock investigation in alumina-based refractory
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
The thermal shock behavior of large grain size, alumina-based refractories was investigated experimentally using a standard water quench test. A mathematical model was employed to simulate the thermal stability behavior. ...
Determination of thermal shock resistance of silicon carbide/cordierite composite material using nondestructive test methods
(Elsevier Sci Ltd, Oxford, 2008)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70 and 50:50. Behavior of composite ceramics after thermal ...
Cavitation damage of the medium carbon steel: Implementation of image analysis
(Elsevier Science Bv, Amsterdam, 2008)
Cavitation damage of the medium carbon steel was performed using the modified vibratory cavitation test set up. Erosion rates were measured by analytical method. The morphology of damage under cavitation action was determined ...
Thermal stability of cordierite/silicon carbide composites after cyclic thermal shock
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
In this paper composite material made from silicium carbide and cordierite was used in experiments. Behavior of the material in conditions of rapid temperature changes was investigated. Modified water quench test was applied ...
Microstructural dependence of fracture toughness in high-strength 7000 forging alloys
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The effects of microstructural parameters associated with the coarse intermetallic phases particles and precipitates on the fracture toughness of the overaged 7000 alloy forgings are investigated. Detailed microstructural ...
