3.4. Impact strength
Fig. 7 shows the total impact energy of AM100 alloy and its composites as a function of fibre volume frac- tion. The impact energy required for fracture reduces rapidly with addition of ceramic reinforcements, whichis due to their inherently brittle nature. For both the al- loy and its composites, the presence of notch increases the stress concentration at the tip of the notch leading to a further reduction in the impact energy [7, 12, 21]. Fractographic evidence of the unreinforced alloy shows dominant intergranular failure (Fig. 8a). This is due to the reason that the base alloy is inherently brittle due to the presence of brittle Mg17 Al12 precipitates along the grain boundaries [12, 13]. Hence, addition of fibres would lead to the formation of these brittle precipitates at the fibre/matrix interface resulting in easy propaga- tion of cracks under impact loading. This can be ob- served from Fig. 8b, which shows a crack propagating through fibres. Such low resistance to crack propaga- tion results in very low absorption energy [12, 22] and eventually causes intense fibre breakage and fibre chop- ping (Fig. 8b).
