In the present study, nanoindentation creep of novel light-weight Magnesium/Boron Nitride (Mg/BN) nanocomposites containing 0.5, 1.5 and 2.5 vol.% of nano-size BN particulates are studied against monolithic pure Mg. The synthesis of Mg-BN nanocomposites was accomplished using disintegrated melt deposition technique followed by hot extrusion (end products are 8-mm diameter rods). The nanoindentation creep tests were conducted at room temperature using a NanoTest Vantage system via a self-similar pyramidal (Berkovich) indenter. To assess the influence of loading rate on the creep behavior of the materials, the specimens were loaded at the strain rates of 0.005, 0.05, 0.5, and 5 /sec to an indenter displacement (depth) of 2000 nm and were held at the constant load for 500 s. The results of nanoindentation creep tests were correlated and explained using the microstructural characteristics placing special emphasis on the amount of reinforcement and loading rate.
