TEM and FIM/TAP investigations of nanocrystalline CoP
Paper in proceeding, 2002
Performing DSC, TEM, FIM and TAP investigations the microstructural development of Co-1.2wt.% P was investigated. The nanocrystalline microstructure is preserved upon annealing up to 460ºC. Hence, CoP shows a higher thermal stability against grain growth than nanocrystalline Co and Ni-based alloys. Structural relaxation and/or the allotropic transformation may occur before grain growth commences. At 480ºC, however, significant grain growth is observed, Co is transformed (partly) into fcc-structure and Co2P and CoP precipitates are formed.
