Neutron and X-ray diffraction measurements to explore the influence of thermal, mechanical and thermomechanical loadings on the FCC retained phase of two phase HCP/FCC cobalt

Résumé

Thermal and mechanical effects on the phase transformation of polycrystalline two-phase HCP/FCC cobalt have been studied in a coupled and decoupled way. This experimental work has involved in situ X-ray and neutron diffaction analysis to determine phase proportions under various thermomechanical conditions. A quantitative analysis is proposed to better understand phase transformation in a cobalt rolled sheet. Results show that the metastable FCC retained phase can be transformed into HCP phase by a mechanical loading (tensile or stamping). In accordance with the theory and the litterature, the prominent phase (HCP) can subsequently be transformed with an increase of temperature above 470 °C.
