Synthesis and characterisation of advanced ball-milled Al ...

Another advantage of high-energy ball milling lies in its ability to produce bulk quantities of solid-state materials using simple equipment at room temperature. Accordingly, the aim of this work is to synthesize an advanced Al-Al 2 O 3 nanocomposite powder for SLM using HEBM with two different types of milling and pause combinations. Laboratory-scale ball milling (5–100 mL scale) is a batch process, whereas industrial ball mills can be operated in a continuous mode, thus offering a very high synthesis throughput. The milling occurs due to mechanical friction between the grinding medium, such as balls of the same or various sizes, and the ground material ( Figure 1 ).
