Analysis of different inhibitors for magnesium investment casting
Herrero-Dorca, Nuria; Hurtado, Iñaki; Arruebarrena, Gurutze; Sarriegi Etxeberria, Haritz (IOP Publishing, 2011)Investment casting of magnesium is a well suited process for the production of aeronautic and automotive components. But still, this process has not been properly developed. One reason for that are the reactions between ... -
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 ... -
Effectivity of fluoride treatment on hydrogen and corrosion product generation in temporal implants for different magnesium alloys
Trinidad Naranjo, Javier; Arruebarrena, Gurutze; Hurtado, Iñaki; Sáenz de Argandoña, Eneko (Sage Journals, 2013)The increasing interest on magnesium alloys relies on their biocompatibility, bioabsorbility and especially on their mechanical properties. Due to these characteristics, magnesium alloys are becoming a promising solution ... -
Friction Stir Welding of AA2099-T83 and AA2060-T8E30 Aluminium Alloys with New Cr-Free Surface Treatments and Sealant Application
Hurtado, Iñaki (MDPI, 2021)The feasibility for friction stir welding (FSW) surface-treated AA2099-T83 aluminium extrusions with AA2060-T8E30 aluminium sheets in the overlap configuration and using a sealant at the interface was investigated in this ... -
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 ... -
Influence of Surface Finish and Porosity on the Fatigue behaviour of A356 Aluminium Casting Alloy
Hidalgo, Raquel; Esnaola, Jon Ander; Llavori, Inigo; Larrañaga, Miren; Herrero-Dorca, Nuria; Hurtado, Iñaki; Kortabarria, Aitor (EDP Sciences, 2018)In casting parts, due to the manufacturing process, the presence of defects such as porosity, inclusions and oxide films is unavoidable. All these irregularities have a negative effect on the component ... -
Initiation of dynamic recrystallization of as-cast N08028 alloy
Mora Serrano, Elena; Mendiguren, Joseba; Hurtado, Iñaki (ESAFORM, 2021)The use of high nickel content austenitic stainless steels (SASS) has significantly increased in the last decade. The corrosion and high fatigue resistance of these materials make them suitable for manufacturing oil country ... -
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 ... -
