| Abstract Scope |
In this energetically enunciated presentation the salient aspects of an aluminium alloy reinforced with particulates of titanium diboride (TiB2) will be highlighted. Salient aspects specific to measurement of damping capacity using experimental modal analysis will be detailed. The tribological behaviour of the engineered aluminium alloy metal matrix composite and the role and contribution of different sliding variables was established through pin-on-disc tests. The damping capacity of the TiB2 particulate-reinforced aluminium alloy revealed an observable improvement over the as-cast counterpart and comparable to grey cast iron. The intricacies specific to tribological behaviour of the engineered aluminium alloy composite was established with respect to microscopic segregation of the particulate reinforcement (TiB2) coupled with the role of test parameters. The fundamental strengthening and damping mechanism governing behaviour of the chosen composite will be elucidated in light of the conjoint and mutually interactive influences of reinforcement agglomeration, nature of loading and interfacial bonding. |
