ABSTRACT
In the current scenario, industries are increasingly concerned with sustainability, which has resulted in lower product costs, less waste, and waste recycling. The bulk of products in the manufacturing sector are produced by machining, which generates massive amounts of metallic trash in the form of chips. However, when it comes to materials such as titanium, which is expensive and difficult to access, the demand for recycling will become much more pressing. There are several ways to recycle titanium chip material into feedstock material, including vacuum sintering, plasma sintering, gas atomisation, and ball milling. Among all approaches, ball milling produced promising results in terms of achieving sphericity while consuming less energy than other methods. As this is an underdeveloped technology, there is a substantial need for characterisation to investigate the physical, mechanical, and morphological properties of the output ball-milled powder. This chapter discusses the characterisation of ball-milled titanium powder, including classification, characterisation, application, challenges, and its future scope.
