Development of Aluminim/Steel hybrid structures by semisolid forming
Echaniz Hernández, Erik (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2016)Weight reduction is the most cost-effective mean to improve fuel economy and greenhouse gas emissions from the transportation sector. Combining steel and aluminum in a hybrid structure will implement the integrated ... -
Effect of Boron Content and Cooling Rate on the Microstructure and Boride Formation of β-Solidifying γ-TiAl TNM Alloy
Bernal Rodríguez, Daniel; Chamorro Sánchez, Xabier; Hurtado 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 ... -
Engatillado mediante conformado electromagnético
Jimbert Lacha, Pedro Jose (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2009)This thesis develops a new application for the Electromagnetic Forming (EMF) technology: the autobody and white panels hemming operation for aluminium alloys. It is a completely new application for this high speed forming ... -
Induction Skull Melting of Ti-6Al-4V: Process Control and Efficiency Optimization
Chamorro Sánchez, Xabier; Herrero Dorca, Nuria; Bernal Rodríguez, Daniel; Hurtado 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 alternative mould materials and inhibitors on mould-metal reactions in magnesium investment casting
Herrero Dorca, Nuria (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2012)Investment casting of magnesium is a process well suited for the production of aeronautic and automotive components, as light density components in medium and small series are obtained. But, still nowadays, this process ... -
Influence of Surface Finish and Porosity on the Fatigue behaviour of A356 Aluminium Casting Alloy
Hidalgo Coca, Raquel; Esnaola Ramos, Jon Ander; Llavori Osa, Iñigo; Larrañaga Serna, Miren; Herrero Dorca, Nuria; Hurtado Hurtado, Iñaki; Kortabarria Lezeta, 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 ... -
