In the present work, the study of the phase transformations in the Ti-407 alloy will be carried out, in particular, the effects of the initial microstructure and the heating rate on the phase transformations that give rise to the formation of the β phase and the cooling rate on the stability and transformation behavior of said phase.
The manufacture of this type of engineering components from Ti-407 alloy represents considerable savings since this material is significantly easier to process and machine, since it exhibits a better combination of ductility and resistance.
The solution heat treatment affects the distribution of elements in the initial microstructure, consequently, the dilatometric curves behave very differently during heating, dissolving the alloying elements differently.
Based on the analysis of the dilatometric curves during constant heating, it was determined that the β-transus temperature starts from ~815°C for the Ti-407 alloy. |
