Influence of TiB2 particles on machinability and machining parameter optimization of TiB2/Al MMCs

open access: yesChinese Journal of Aeronautics, 2018
Abstract In situ formed TiB2 particle reinforced aluminum matrix composites (TiB2/Al MMCs) have some extraordinary properties which make them be a promising material for high performance aero-engine blade. Due to the influence of TiB2 particles, the machinability is still a problem which restricts the application of TiB2/Al MMCs. In order to meet the
