Test methods for high-temperature materials

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 ...

Choose Materials for High - Temperature Environments

tably strength, so corrosion resistance (stability) may not be the primary design consideration. Assemblies need to be strong and resilient to the unique loads and stresses imparted on them, which can include significant temperature changes and thermal gradients for many high-temperature applications. In making a choice, it is necessary to know what materials are available and to what extent th...

Ultrasonic Thermometer for High Temperature Materials Testing

This past year there were a total of 14 faculty members involved in 40 sponsored research projects. Sponsors included government agencies, navy labs and industry. In addition to the sponsored faculty research there were 15 midshipmen involved in independent research projects with faculty, four of which were Bowman Scholars. Many of these projects were also funded by outside sponsors. Overall, 2...

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...
