Abstract Scope |
Effect of substitution of transition elements from Zn to other 3d elements on the formation and stability of LPSO structures is an interesting subject to understand microstructure control of the alloys. In the present work, phase transformation process in amorphous Mg85Y9Cu6 alloys during heating the sample at a constant rate of 10 K/min. has been analyzed by in-situ small- and wide- angle scattering/diffraction measurements. Results were compared with those previously obtained for Mg85Y9Zn6 alloys, which we have examined in detail[1]. Present results suggest that the tendency to form solute clusters in supersaturated hcp matrix is far less remarkable when compared with that for MgYZn alloys. Nucleation sites of the LPSO crystallites were found to be different when compare the path with the MgYZn alloy under the same heat treatments.[1] H.Okuda et al., Acta Mater. 194(2020)587. |
