TEM Study of the Multiple Phase Partitionless Microstructure Evolution in Rapidly Solidified Ni-V and Co-Al Alloys. Sieber Allen, P.
Paper abstract bibtex A transmission electron microscopy characterization of splat quenched (SQ) foils of Ni-49V and Co-18.5Al showed a duplex partitionless formation of both face centered cubic (bcc) and body centered cubic (bcc) phases. In rapidly quenched Ni-V foils, a fcc, a bcc and an intermetallic σ phase were formed simultaneously. The microstructure of the alloy changed with the position on the SQ foil and with decreasing cooling rate from the edge towards the center of the quenched foils. While in Co-Al foils, a fcc and an ordered bcc were developed. The partitionless phase evolution patterns observed in both systems were compared and considered in terms of the kinetic constraints imposed by the novel microstructure.
