Resumo(s)
Chips are obtained by subtractive processes such as machining workpieces and until
recently considered as waste. However, in recent years they are shown to have great potential as
sustainable raw materials for powder technologies. Powder production from metal chips, through
the application of solid-state processes, seems to be an alternative to conventional atomization from
liquid cooled with different fluids. However, chip material and processing have an essential role in
the characteristics of powder particles, such as particle size, shape, size distribution and structure
(4S’s), which are essential parameters that must be considered having in mind the powder process
and the metallurgy applications. Moreover, different approaches refereed in the application of
this new “powder process” are highlighted. The goal is to show how the actual research has been
transforming subtractive processes from a contributor of wastes to clean technologies.
