| description | The phase composition before deformation is an important factor affecting the deformation mechanism of titanium alloy at room-temperature. In practical production, the initial phase composition can be greatly controlled by changing the solution cooling mode of the alloy, thus affecting the deformation mechanism and mechanical properties of the alloy to a certain extent. Therefore, the study of the effect of solution cooling rate on the deformation mechanism at room-temperature plays an important role in regulating the properties of the alloy. Through room-temperature compression experiments, the microstructure evolution and room-temperature plastic deformation mechanism of Ti–10Mo–1Fe near β-type alloys with different cooling rates after solution treatment at 870 °C were studied in this paper. The results show that the main room-temperature deformation mechanism of the Ti–10Mo–1Fe alloy under rapid cooling conditions (water-cooled) was the {332}<113> twins and stress-induced orthorhombic martensite α″ phase. In addition, a few {112}<111> twins were observed. The plastic deformation mechanism at room temperature under moderate cooling conditions (air-cooled) was primarily {332}<113> twins and dislocation slip. Small numbers of {112}<111> twins were also observed. Under slow cooling conditions (furnace cooling), no new phases are formed during the deformation process, and the plastic deformation mechanism at room temperature is dislocation slip. |
