Effects of mechanical milling on the properties of Mg-10.3% Ti and Mg-5% Al-10.3% Ti metal-metal composite

The mechanical properties of Mg-10.3% Ti and Mg-5% Al-10.3% Ti metal-metal composites produced via mechanical milling have been studied in the present paper. Strain to failure was found to have dramatically increased after the milling process. The Hall-Petch constant K for Mg-10.3% Ti composite was found to be 2254 MPa/nm−1/2 while a negative value was found for Mg-5% Al-10.3% Ti.
