Investigation microstructure and mechanical characteristics of sugar palm fibre ash reinforced LM26 Al-matrix composites

Aluminium alloy of grade LM26 was used as a matrix and sugar palm fiber ash (SPFA) as reinforcement to investigate its microstructural and mechanical characteristics. Stir casting, a cost-effective method of casting was utilized to fabricate the composites, by altering SPFA from 0 to 10 wt% in 2 wt%...
