EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

The present work highlights a promising manufacturing route of equiatomic NiTi alloys which is characterized by a short duration mechanical alloying (MA) step (25.0 min at 300 rpm) followed by a spark plasma sintering (SPS) step (750 ºC for 2.5 and 7.5 min, using a pressure of 51 MPa). The processed materials were characterized by X-ray diffraction, scanning electron microscopy, density, and...

REFeB permanent magnets have drawn attention due to their excellent magnetic properties and wide applications, such as in magnetic resonance imaging, electric vehicle, wind generator, factory automation system etc. Usually magnets are made by sintering pulverized powder obtained through strip casting or melt spinning process, but these traditional methods are complex and powders can be easily...

Interconnected pore graphite foams have proven to be excellent materials for thermal management applications due to their superior property combination. Traditionally, the most successful foaming methods, which involve blowing graphite precursors such as mesophase pitch, have a number of drawbacks: there is no perfect control over the volume fraction of pores generated, and control of the...

Nowadays, climate change and environmental degradation have become drivers for technology developers, in particular for Material Science. The traditional developers approach, based on the mere study of mechanical, chemical, etc. properties, have demonstrated its limits. The production of many materials present high potential environmental impacts throughout their life cycle, that is reflected...
