The evolution of microstructure and mechanical properties of ATI 718Plus® superalloy subjected to a graded solution treatment was evaluated. Graded solution treatment was performed on a single bar of 718Plus superalloy for 1 hour within a temperature range of 907 °C to 1095 °C. It resulted in a graded microstructure investigated mainly by light microscopy, scanning-, and transmission electron microscopy. A quantitative analysis of identified phases was performed. Mechanical properties were assessed using the Vickers hardness test and correlated with the microstructural changes. The structure–property relationship between 718Plus superalloy microstructure and mechanical properties was established. The change of the γ phase grain size in the single-phase range did not affect the hardness in a meaningful manner. Significant increases in hardness were observed after the introduction of γ′ and η phases. Phase stability limits were determined experimentally and compared with those calculated using the Thermo-Calc software. [ABSTRACT FROM AUTHOR] |
