Correlation of Dynamic Elastic Properties of a Heat-Treated CoNiAl Alloy System with Its Microstructural Changes

摘要: Elastic responses of a solid represent structural properties and their changes as function external parameters like heat treatment. Heat treatment is standard way to suitably alter the physical an alloy. Here effects different annealing temperatures on polycrystalline Co–Ni–Al (Co36Ni36Al28) samples were investigated in detail using X-ray diffraction electron microscopy that showed significant phase fractions, B2 austenite (β), non-FSMA A1 (γ), Martensite L10$$(\beta^{\prime})$$ at room temperature. These turn affected transition temperatures, electrical resistivity, magnetic samples. Using resonant ultrasonic spectrometer (RUS), dynamic elastic measured temperature, results found reflect evaluations correctly. This first time RUS measurements are reported this alloy system. All these findings can be used fine tune sample for desired application.
