Unveiling interrupted rolling strategy as post-processing impact on dual phase mechanical characteristics and microstructure Mg-8%Li/ bagasse nanoparticle composite

Abstract

This study examines the impact of sporadic rolling on the mechanical properties and microstructures of the Mg-8% Li/bagasse nanoparticle composite. Using the stir casting method, bagasse nanoparticle-reinforced composites were developed and rolled with thickness reductions of 50, 70, and 90%. Research on the microstructures of rolled composites shows that when aspect ratio decreases, fine, elongated grains grow in thickness and decrease in reduction. Additionally, it can be seen that by increasing the percentage of rolling, the beta phase dissolves and the ductility of the composite is decreased. Comparing the interrupted rolled sample to the as-cast composite, the hardness is greater. At a 90% reduction, the yield has greater yield strength of 223 MPa. Because of the effective reduction in particle size, the hardening capability of composites reduces as the reduction percentage increases. It has been established that interrupted rolling affects the mechanical and microstructures of Mg-8% Li/bagasse nanoparticle composite.
