BMS College of Engineering, India
67th World Foundry Congress
Aluminium based metal matrix composite containing 15 weight percentage
of graphite particulates as reinforcement was synthesized using
stir-casting method. The properties like hardness, dry sliding wear
resistance and slurry erosive wear resistance of the composites were
investigated. Strip fluidity test was conducted to asses the flowability of the
melt mixture. The results of wear studies, both sliding wear and slurry
erosive wear, hav...

The present paper is dealing with the enhancement of aluminium die
casting tools, thanks to a patented coating, carried out by the PVD
process.
The choice of the coating constituents is based on a very low chemical
affinity with aluminium and alloys. The composition is chosen so as to
provide the highest hardness, and by consequence, the best abrasion
resistance. The thermodynamic stability is also controlled up to 800 °C
(1472 °...

Microstructure observations and refining performances of At-Ti-C master alloys prepared by salt route
Dr. Ashok Sharma
Professor and Head, Malaviya National Institute of Technology , India
67th World Foundry Congress
In the present investigation, influence of temperature on the microstructure
of Al-3Ti-0.15C master alloy has been investigated. It is observed that the
size, surface characteristics and distribution of TiC particles, as well as the
morphology and size of TiAl3 particles are related to melting temperature.
The Al-3Ti-0.15C master alloy synthesized at 1200oC and 60 minutes of
holding time, shown superior grain refining action as compared w...
