摘要
The processing, materials characterization, and applications of spray formed Cu-15Ni-8Sn, Cr12MoV steel, and GCr15 steel are reported in this paper. Spinodal decomposed phase, metastable gamma' pre-precipitates, and discontinuous precipitates exist during aging treatment of spray formed Cu-15Ni-8Sn alloy. The as-sprayed Cr12MoV steel shows the depressed martensite start temperature Ms and the reduced hardenability in comparison with the conventionally processed one. TEM micrographs of the spray formed GCr15 steel reveal the fine pearlite with interlamellar spacing of 85 nm and the martensite of the width of 0.35 mum. (C) 2003 Elsevier Science B.V.
