Microstructural Evolution and Wear Properties of In Situ Al-4.5Cu-5TiB2 Composite Processed in Mushy State


Article Preview

In-situ Al-4.5Cu-5TiB2 composite plates were stir cast with TiB2 particles formed through mixed salt route. The as-cast samples with 30 volume percent liquid content were rolled in mushy state down to 2.5 and 5 percent reduction in thickness per pass. The rolled products found to be defect-free after the first pass were subjected to multiple roll passes in mushy state with identical experimental conditions, adding up to seven. The wear properties of as-cast and mushy state rolled composites were also investigated, and correlated with microstructure.
