The Influence of Li on the Tensile Properties of Al-Mg2Si Metal Matrix Composite
The present research is undertaken to study the influence of Li on the tensile properties of Al-15%Mg2Si metal matrix composite. The tensile test results show that adding 0.15%Li to the composite raises the UTS and elongation values, insignificantly. In the point of fracture behaviour of the composite, the addition of 0.15%Li converts the fracture behaviour from brittle, with cleavage facets, to ductile, with fine ductile dimples.
