Thermal-shock resistance of magnesial refractories

Refractories, 1981
In order to study the thermally induced loss of strength of flat, rectangular specimens, we have proposed a method of evaluating the thermal-shock resistance of the materials based on a determination of the thermal load corresponding to the half-loss of strength of the specimen. In this case, the capacity of the material to work with specified signs of

Dynamic Thermal Shock Resistance

1974
When DUHAMEL /1/, in 1835, had laid down the foundations of thermo-elasticity, he had derived already the coupled heat conduction equation as well as the corresponding equations of motion. With respect to thermally induced waves and vibrations, however, he asserted the following: “I1 est donc permis, surtout a cause de la lenteur avec laquelle s’opere ...

RESISTANCE OF ENAMELS TO THERMAL SHOCK*

Journal of the American Ceramic Society, 1942
A bstract Thermal‐shock resistance tests were made on enamels of varying thermal expansions applied on test pans. Increased weight of application and high expansion of the cover coat decreased the thermal‐shock resistance, whereas high expansion of the ground coat increased ...

Thermal-Shock-Resistant Materials

1971
Aerospace applications which take advantage of the refractory nature of ceramic materials also impose upon them severe conditions of thermal shock. The severity of this thermal environment exceeds that for which it is possible to prevent crack nucleation; therefore, the design of thermal-shock-resistant materials is based on the concept of preventing ...

Analysis of thermal shock resistance of solids based on the nonlocal elastic theory, Part II: Thermal shock cracking and thermal shock resistance

WIT Transactions on Engineering Sciences, 2014
This is the continuity of the Part I of this research. In this part, the thermal shock resistance behavior of a plate subjected to a sudden thermal load will be studied. Two types of crack problems are solved: an edge crack under cold shock and a center crack under hot shock.

Quantitative Evaluation of Thermal-Shock Resistance

Journal of Fluids Engineering, 1956
Abstract The dependence of thermal-shock resistance on two parameters k and σf/Eα (when k is conductivity, σf the fracture stress, E the elastic modulus, and α the coefficient of thermal expansion) is experimentally demonstrated by the fact that the relative ratings of two materials may change with a change of quench severity. The theory

Heat shock proteins and thermal resistance in yeast

Biochemical and Biophysical Research Communications, 1980
Abstract A rapid shift in cultivation temperature of Saccharomyces cerevisiae from 23° to 36° results in protection from death due to extreme heat treatment (52°). The level of this acquired thermal resistance shows an excellent correlation with the cellular level of the heat shock proteins which are transiently induced by such a temperature ...

Thermal shock resistance of porcelain discs.

Journal of dental research, 1983
Thermal shock testing of opaque porcelain-body porcelain discs and body porcelain discs was performed on three porcelain products. Significant differences exist between the mean failure temperature differentials, delta T, for the composite opaque-body porcelain discs.

Thermal Shock Resistance of Cordierite-Mullite Refractory Composites

Key Engineering Materials, 2005
The design of composite materials leads to the development of multi-component systems where each constituent has a specific function in the material, from technological and/or application points of view. Examples of such composite systems are the cordierite-mullite refractory materials investigated in this contribution.
