The results show that the addition of Ni and Si elements leads to obvious coarsening behavior of the α-Fe dendrites in the Cu-20Fe alloy. In addition......
of bimodal microstructure at 1140°C is explored. The data shows formation of a duplex size precipitate microstructure after 5 min of the aging. Formation mechanism of the duplex structure is discussed. Coarsening and dissolution mechanisms at 1120°C are discussed. Precipitates are found to grow up to a critical size in coherent and cubical morphology, beyond which dissolution sets in. 关键词:precipitation......
