摘要: Abstract The present article investigates the age hardening behavior of thixoformed A356–5TiB 2 in-situ composite prepared by a salt-metal reaction. non-dendritic feedstock for thixoforming was cooling slope casting technique. results show that attains peak hardness in only four hours. detailed microstructural analysis shows enhanced ageing can be attributed to high dislocation density generated α-Al matrix due thermal mismatch and process itself. Furthermore, it found not increases tensile strength peak-aged condition but also ductility ~7.4%.
