Insights into interrupted rolling strategy as post-processing impact on dual phase tribological behaviour properties of Mg-8%Li doped bagasse nanoparticles composite

Abstract

Abstract A combined effect of percentage reduction in rolling and weight percentage bagasse nanoparticles were used to improved the wear behaviour of Mg-8% Li/bagasse nanoparticle composites for the first time. The composites were produced using the double stir casting method by varying bagasse nanoparticles from 1 to 3%. The interrupted rolling process was used to reduce the samples to 50, 70, and 90%. The microstructural, hardness, and wear properties of the rolled composite were investigated. The results show that interrupted rolling lessen macrocracking and increase the rolled sample's formability. At 90% rolled reduction and 3% bagasse addition, the sample's hardness values improved to 74%. The coefficient of friction and wear resistance improved; with 90% rolled work exhibiting the highest wear resistance. Adhesion and delamination were the main wear processes in the as-cast samples; in the rolled samples, abrasion was the predominant wear mechanism. This study showed how to make Mg-8% Li-bagasse nanoparticle composites more resistant to wear by combining the effects of bagasse nanoparticles and rolling reduction.
