Consolidation of Lightweight Alloy Powders: Overcoming the Problems During Pressing and Sintering of Low-Dense Alloy Powders like Aluminium, Magnesium, Titanium, and Beryllium Alloys

The process of consolidating lightweight alloy powders, which includes materials such as aluminium, magnesium, titanium, and beryllium, plays a crucial role in the production of high-performance components in many sectors. Nevertheless, the pressing and sintering processes of these alloys are accompanied by specific difficulties arising from their low density, reactivity, and particular material features. This chapter examines novel methodologies for overcoming these obstacles and improving the compaction of lightweight alloy powders. The study encompasses several aspects including powder modification techniques, innovative binder systems, additive manufacturing methods, examination of microstructure, evaluation of mechanical and thermal properties, as well as issues related to environmental and safety factors. Through a comprehensive analysis of existing scholarly works and the implementation of empirical investigations, the primary objective of this study is to offer significant perspectives on the advancement of effective consolidation methodologies. This endeavour has the potential to bring about transformative changes in sectors heavily reliant on lightweight alloys.
