The microstructure and properties of a powder-processed copper-niobium alloy.

摘要

High pressure gas atomization (HPGA) has been used to produce rapidly solidified Cu-21.2Nb-1.8Mo (wt%) alloy powders with a range of microstructures found to be dependent on powder size. Specifically, the microstructures of fine-scale powders (;The thermal stability of the HPGA materials was also analyzed in terms of the resistance of the Nb-rich dispersions to coarsening during high-temperature (900
