摘要：

The precipitation of A type partially coherent precipitates occurring in the first step of the structural hardening of the 15-5 PH martensitic stainless alloy was studied by anomalous small angle X ray scattering at four absorption edges (KCr, KFe, KNi and KCu). An important anomalous effect was clearly observed at the KFe and KCu absorption edges. The precipitation occurs according to the two-phase model. Considering our alloy as a pseudo-ternary one (Cr+Ni, Fe, Cu), it has been possible to determine the slope of the tie-line corresponding to the precipitation taking place at 500-degrees-C.
