Formation mechanism of microporosity in complex nickel-based single crystal casting

Show other versions (1)

Microporosity in the body and platform of the three different compositions complex nickel-based single crystal castings solidified by high rate solidification (HRS) process was investigated by the X-ray tomography (XRT). The results show that the solidification range and the dendrite tortuosity have...
