Nickel-based superalloys are widely employed to manufacture aero-engine turbines due their high mechanical strength and resistance corrosion creep. Vacuum Induction Melting (VIM) is a suitable manufacturing technology because of the reactive nature alloying elements; however, melting process time-consuming energy-demanding. This research focuses on increasing overall efficiency in two ways. Initially, studying influence metal-containing crucible composition thermal properties melting. In...
Titanium investment casting is one of the leading and most efficient near-net-shape manufacturing processes, since complex shape components are possible to obtain with a very low amount material waste. But melting these reactive alloys implies usage specific technologies such as Induction Skull Melting (ISM) method. In this work ISM was extensively studied aim deepening characteristics method improving too energy efficiency overall process performance. A 16 segment copper crucible 3 turns...
Boron is a unique and popular grain refiner element in cast titanium aluminide (TiAl) alloys, as it helps to improve mechanical properties if properly alloyed. However, the formation mechanism of different types borides TiAl alloys not yet clearly understood. This study seeks correlate chemical composition cooling rate during solidification with type boride precipitated resulting microstructure. Several β-solidifying γ-TiAl TNM family were cast, alloying boron starting Ti-44.5Al-4Nb-1Mo-0.1B...
The conventional processing route of TNM (Ti-Nb-Mo) alloys combines casting and Hot Isostatic Pressing (HIP) followed by forging multiple heat treatments to establish optimum properties. This is a time-consuming costly process. In this study we present an advanced alternative alloy combining HIP into single process, which refer as IHT (integrated treatment), applied modified with 1.5B. A Quintus lab unit quenching module was used, achieving fast controlled cooling, differs from the slow...
