Al 3 Ti/ADC12 Composite Synthesized by Ultrasonic Chemistry in Situ Reaction
Source abstract
Abstract
Abstract Al 3 Ti/ADC12 composite was synthesized in situ using Al-fluoride potassium titanate (K 2 TiF 6 ) as the reaction system and an ultrasonic assisted direct melt reaction. Results indicate ultrasonic chemistry reactions are both accelerated and more complete compared to traditional in situ reactions. Al 3 Ti reinforced particles with a regular shape and size of 1-2 μm were well distributed and as-cast microstructures of composites were superior. Composite particles under ultrasonic assistance were also refined to a greater extent. Tensile strength and elongation rate of the composites reached 255 MPa and 2.2%, an increase of 19.1% and 37.5% respectively to those without ultrasonic aid. Cleavage surface of the composite declined and the number of dimples increased while dimples became smaller and deeper, showing obvious ductile fracture.
