HIGH TEMPERATURE ELASTIC PROPERTIES OF REFRACTORY MATERIALS
Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...
متن کاملHigh Temperature Behavior of Dual Phase Steels
Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...
متن کاملThe compositional variation of synthetic sodic amphiboles at high and ultra-high pressures
Sodic amphiboles in high pressure and ultrahigh pressure (UHP) metamorphic rocks are complex solid solutions in the system Na2O±MgO±Al2O3±SiO2± H2O (NMASH) whose compositions vary with pressure and temperature. We conducted piston-cylinder experiments at 20±30 kbar and 700±800 °C to investigate the stability and compositional variations of sodic amphiboles, based on the reaction glaucophane 2...
متن کاملHigh Energy Laser Optics
-This paper reviews br ief ly the theoretical understanding and properties of optical resonators. Starting from the theory of stable laser resonators, unstable resonators are discussed with emphasis on understanding the i r properties tha t ensure near diffraction limited performance of higb power lasers. The growing f i e ld of adaptive optics for laser transmission i s a lso examined as an ad...
متن کاملHigh-Density Integrated Optics
This paper presents two-dimensional (2-D) finite difference time domain (FDTD) simulations of low-loss rightangle waveguide bends, T-junctions and crossings, based on high index-contrast waveguides. Such structures are essential for the dense integration of optical components. Excellent performance characteristics are obtained by designing the waveguide intersection regions as low-Q resonant ca...
