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 ...

Transition temperature and a spatial dependence of the superconducting gap for multilayer high-temperature superconductors.

We derive the expressions for the transition temperature (Tc), and the spatial dependence of the superconducting gap for a multilayer high-Tc superconductor composed of groups of tightly spaced planes separated by a larger distance. The results are compared with experiment and provide a strong support for an interlayer hopping as the driving force of the large Tc enhancement in multilayered com...

Pairing Symmetry of the High Temperature Superconductors

A review of relevant experiments that favour an unconventional pairing symmetry in high temperature cuprates is made. Results of magnitude sensitive techniques are discussed and then tests which probe directly the phase of the order parameter are presented in more detail. Josephson eeect and its relevance to this problem is described. Consensus resulting from compelling arguments for a d x 2 ?y...

I-V characteristics of high-temperature superconductors with columnar defects.

The vortex glass transition in the presence of columnar defects is studied by Monte Carlo simulations of a vortex loop model, suggested by the analogy to the T = 0 superconductor-insulator transition for dirty bosons in (2+1)D. From finite-size scaling analysis of the I-V characteristic we find two dynamical exponents describing the non-equilibrium behavior. We obtain z⊥ = 6±0.5 and z‖ = 4 ± 0....

Considerations of Well Cementing Materials in High-Pressure, High-Temperature Conditions (RESEARCH NOTE)

As worldwide demand of hydrocarbon is growing fast, the oil and gas companies have been forced to explore reservoirs with more hostile conditions, such as high-pressure, high-temperature conditions. Improved technology, material selection and testing procedures are required to overcome the common problems in these conditions. One of the main phases of well construction is cementing job. Appropr...
