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 ...

Application of High Temperature Lead-free Solder Materials in Medicine

With the recent rapid advances in medical technology there are a variety of intrusive procedures used in the medical industry today requiring tools, instruments, sensors and components in materials that are inert with respect to reactions with the body. More, new surgical techniques have been developed to improve the quality of operations, reduce the risk to patients and reduce the pain experie...

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...

High Temperature Materials and Mechanisms

Given the wide topic coverage and the sometimes introductory character of the book, it is not helpful that only 21 bibliographic entries are provided for the entire book. The offer of a wider bibliography selection would significantly improve the usefulness of the book, since its topic diversity is likely to require for most readers additional reading on some of the topics. Dr M. Sergio Campoba...
