Local Structure Study of spinodal decomposition in Copper-Nickel-Tin alloy using EXAFS.

Ternary copper-nickel-tin (CuNiSn) alloy shows spinodal decomposition by controlled heat treatment. Mixing of Tin(Sn) in very low quantity in Copper Nickel alloy gives rise to spinodal decomposition at moderate temperature and very less time. To detect the two separate phases in spinodal decomposition, Extended X-ray Absorption Fine Structure (EXAFS) measurement is used. In the present manuscript, EXAFS study at both Copper and Nickel K-edges on a set of Copper-Nickel-Tin alloy (CuNiSn) samples prepared with time dependent heat treatment for spinodal decomposition is presented.
