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 کاملFriction and wear of restorative dental materials.
Many different instruments have been developed for the measurement of friction and wear.1-5 Often the instrument was designed to accommodate some particular type of material, environment, or test condition. Studies reported in the dental literature have been limited to wear measurements with simulated toothbrushing methods,6-9 or on prosthetic teeth mounted on an articulator.10 This study will ...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولLinear elastic properties of 2D and 3D models of porous materials made from elongated objects
Porous materials are formed in nature and by man by many different processes. The nature of the pore space, which is usually the space left over as the solid backbone forms, is often controlled by the morphology of the solid backbone. In particular, sometimes the backbone is made from the random deposition of elongated crystals, which makes analytical techniques particularly difficult to apply....
متن کاملFoam Materials Made from Carbon Nanotubes
1.1 What is CNT foam? Foam is a macroporous material and comes in many forms, such as polystyrene shock absorbers, dish-washing sponges, and foam board insulation. This chapter describes a technique to prepare foam materials from carbon nanotubes (CNTs). The use of a CNTmade foam as a kitchen sponge may not be a good idea, however. We of course expect the nano-carbons to have a specific functio...
