Enhancing Materials and Device Analysis Capability in the SEM and FIB-SEM by using a Nanomanipulator
Nanomanipulators, whilst commonly used to lift out TEM samples prepared in the FIB, have a number of other potential applications and can aid in the chemical and crystallographic analysis of samples. Here, we discuss some of these alternative uses of nanomanipulators and show how they enable the EDS and EBSD analysis of thin samples in the FIB-SEM as well as serve as electrical probes and enabl...
متن کاملHIGH 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 کاملPresent State of TEM-SXES Analysis and its Application to SEM aiming Chemical Analysis of Bulk Materials
X-ray emission spectroscopy is widely used as a practical tool for compositional analysis of local specimen area and elemental mapping analysis in electron microscopes. X-rays with energy more than a few keV are dominantly due to electronic transitions between inner-shell electron levels. Those characteristic X-ray energies are useful for assignment of elements. On the other hand, X-rays origin...
متن کاملNEW REFRACTORY MATERIALS FOR THE COPPER INDUSTRY
Wear of various basic refractory materials to substitute to currently used magnesia chrome bricks has been studied, measuring matte and slag penetration and dissolution, through different cup and rotary slag tests. High magnesia with and without impregnation, magnesia graphite, magnesia-alumina spinel with and without impregnation, olivine-magnesia and olivine magnesia- graphite bricks, as well...
