Fracture at elevated temperature
Metallurgical Transactions A, 1977We have carried out a systematic experimental study of fracture in materials which contain hard second phase particles. The principal variables in this study were the average size and spacing of the second phase particles, grain size, temperature, and the strain rate.

Nitroxide-Mediated Polymerization at Elevated Temperatures
ACS Macro Letters, 2015A new alkoxyamine based on a highly thermally stable nitroxide is used for the controlled polymerization of styrene and butyl acrylate at temperatures up to 200 °C. High monomer conversions are reached in a few minutes with a linear increase in polymer chain-length with conversion, a final dispersity (Đ) of ∼1.2, and successful chain-extension of the ...

Reduction of Permeability in Granite at Elevated Temperatures
Science, 1994The addition of hydrothermal fluids to heated, intact granite leads to permeability reductions in the temperature range of 300° to 500°C, with the rate of change generally increasing with increasing temperature. The addition of gouge enhances the rate of permeability reduction because of the greater reactivity of the fine material.

Strontium Sorption on Hematite at Elevated Temperatures
Journal of Colloid and Interface Science, 1999Acid-base reactions and surface complexation of Sr(II) at the hematite/water interface have been studied by means of potentiometric titrations at three different temperatures: 25, 50, and 75 degrees C. Equilibrium measurements were performed in 0.1 M NaCl. In the evaluation of equilibrium models for the acid-base reactions and complexation reactions in

Elevated environmental temperature and methamphetamine neurotoxicity
Environmental Research, 2003Amphetamines have been of considerable research interest for the last several decades. More recent work has renewed interest in the role of ambient temperature in both the toxicity and neurotoxicity of these drugs. We have determined that the striatal dopaminergic neurotoxicity observed in the mouse is linked in some fashion to both body and ...

Temperature elevations in orthopaedic cutting operations
Journal of Biomechanics, 1982Temperature measurements were made in bovine cortical bone using two cutting burst at 20,000 and 100,000 rpm and two reciprocating saw blades at 20,000 strokes per minute. A combination of feed rates and depths of cuts were investigated for the cutting burs.

Oxidation at Elevated Temperatures
1955Corrosion investigations on ferritic stainless steels have shown that initial oxidation takes place by the formation of a thin oxide substrate on which nodules of oxide nucleate and grow (1). Extensivepreliminary work sponsored by the International Nickel Co.

Abstract Elevated-temperature failures are the most complex type of failure because all of the modes of failures can occur at elevated temperatures (with the obvious exception of low-temperature brittle fracture). Elevated-temperature problems are real concerns in industrial applications.
