Unformatted text preview: You may still use G=26 GPa, b=0.286 nm. The (tensile) yield strength of aluminum is Y =40 MPa and that of alumina (Al 2 O 3 ) is 5000 MPa. Problem 4. With the information provided for Problem 3, estimate the strength over that of pure aluminum for a volume fraction of Al2O3 of 5% and a particle size of 100 nm. Problem 5. At what particle size does the mechanism of dislocation motion through the precipitates change? 4.46 nm....
