... N 4 ) , as a sintering aid, was rapidly consolidated using P 2 C ® to inhibit grain growth and ensure high strength and ductility of the consolidated material. The consolidated specimens were 93.5% of theoretical density. The microstructure of the consolidated material was characterized using...

... p to account for strength, the strain energy density W to account for both tensile ductility and toughness, and the material’s density ρ . The effects of differences in chemical composition and heat treatment conditions on the mechanical performance of cast magnesium alloys have been assessed...

...Chris Barlow; Vipin Kumar; Brian Flinn; Rajendra K. Bordia; John Weller The effect of density (relative densities 0.33 to 0.90) on the impact behavior of microcellular polycarbonate (PC) was investigated. Cell size and foaming gas content were also considered. Flexed-beam Izod impact tests were...

... correlated with the associated total strain energy release rates and the results are summarized in Fig. 8 , showing good correlation in both cases. A more practical approach may be to use global indicators such as crack density or stiffness reduction. Further work is to explore the relationship between...
