Prediction capabilities include temperatures, pressures and velocities during filling, freezing times, macro and microshrinkage distributions, Niyama coefficients, local freezing times, primary dendrite arm spacings (Al alloys), steady-state die temperature distributions, mold temperatures, cooling rates and temperature gradients.
Microporosity was observed in both castings most likely as the result of microshrinkage sometimes associated with low-carbon equivalent iron.
minimized defects like microshrinkage by using short and medium freezing range copper alloys;
All of these attributes are related to eutectic graphite and graphite shape, which are important factors for controlling the microshrinkage that occurs at the late stage of solidification.
