| Summary: | In this work, alpha (a) brass was poured in green sand mould and metallic chill mould at about 1050°C.
Sand casting method and metallic chill casting method are representing the slow and fast cooling rates of
the castings, respectively. The slow cooling rate in the sand mould produces larger grains, while the metallic
chill mould produces smaller grains in the castings. As the grain size decreases, the strength of the cast
brass increases; micro-porosity in the casting decreases and the tendency for the casting to fracture during
solidification decreases. Thus, the faster cooling rate casting offers higher strength, density and hardness
compared to the slow cooling rate casting. |
