Abstract: In this paper we present new results on magnetic and magnetoelastic uniformity measurements on Fe78Si7B15 amorphous ribbons and wires. The measurements are performed using an automatic instrumentation device based on the magnetostrictive delay line technique, with the ability to determine the B(H) and (H) functions along the length of a ribbon with parametric control of field and frequency. According to these results, it has been determined that magnetic and magnetoelastic uniformity functions are subject to the history of the under test samples.

Abstract: Some of the activities of the Laboratory of Manufacturing Technology of the NTUA in manufacturing engineering are reported, focusing onto some recent trends and developments in advanced manufacturing of advanced materials, in the important engineering topics nowadays from industrial, research and academic point of view: nanotechnology/nanostructured materials, synthesis and net-shape fabrication of superconductors, biomedical engineering and solar energy devices.
