Effect of Boron Content and Cooling Rate on the Microstructure and Boride Formation of β-Solidifying γ-TiAl TNM Alloy
Bernal, Daniel; chamorro, xabier; Hurtado, Iñaki (MDPI AG, 2020)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 of borides ... -
Effect of the crucible composition on the Inconel 718 vacuum induction melting process efficiency
Garcia-Michelena, Pablo; chamorro, xabier; Herrero-Dorca, Nuria; Bernal, Daniel; Hurtado, Iñaki (Elsevier, 2023)Nickel-based superalloys are widely employed to manufacture aero-engine turbines due to their high mechanical strength and resistance to corrosion and creep. Vacuum Induction Melting (VIM) is a suitable manufacturing ... -
Effects of Different Si Content and Thermal Stories on the Secondary Phase Formation, Hot Ductility, and Stress Rupture Properties of Alloy 718 Investment Castings
Bernal, Daniel (Springer, 2023)Herein, the effects of microstructure on high-temperature properties (hot ductility and stress rupture life) were investigated in alloy 718 investment castings manufactured with different Si contents (0.051, 0.11, and 0.17 ... -
Hierarchical microstructure design and cast processing route of a modified TNM gamma TiAl alloy
Bernal, Daniel (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2021)Gamma titanium aluminides following the β-solidifying pathway, are intermetallic alloys that have the potential to replace heavier materials in high temperature structural applications, such as aerospace and aeronautics. ... -
Induction Skull Melting of Ti-6Al-4V: Process Control and Efficiency Optimization
chamorro, xabier; Herrero-Dorca, Nuria; Bernal, Daniel; Hurtado, Iñaki (MDPI AG, 2019)Titanium investment casting is one of the leading and most e cient near-net-shape manufacturing processes, since complex shape components are possible to obtain with a very low amount of material waste. But melting these ... -
Integration of Hot Isostatic Pressing and Heat Treatment for Advanced Modified gamma-TiAl TNM Alloys
Bernal, Daniel; chamorro, xabier; Hurtado, Iñaki (MDPI, 2022)The conventional processing route of TNM (Ti-Nb-Mo) alloys combines casting and Hot Isostatic Pressing (HIP) followed by forging and multiple heat treatments to establish optimum properties. This is a time-consuming and ...
