Micro Structural and Mechanical Properties of AA 7075/Tio 2 In Situ Composites

Abstract

AA7075/TiO2 in situ composites with different mass fractions of reinforcement were fabricated by stir casting method. During fabrication TiO2 reacts with base alloy and form an in situ composites leading to a uniform distribution of reinforcements. The phase analysis and morphological characterization of composites were studied using x-ray diffraction techniques and scanning electron microscope. Mechanical test were done on the samples to study the behavior during load at different strain rates. Effect of reinforcement and the strengthening mechanism were studied in detail
