Effect of innovative finishing operations on the tribological performance of steel 27MnCr5

Madariaga, Aitor; Abedrabbo Hazbun, Anibal Faruk; Soriano Moreno, Denis; Alpizar Fernandez, Raul; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2022)

Transmission shafts used in the automotive sector must have a good tribological performance, and therefore an enhanced surface integrity. This paper aims to study the effect of eco-friendly innovative finishing operations ...

Effect of liner thermal properties and liner pre-cooling on the thermal management of fast-filling of hydrogen tanks

Blanco-Aguilera, Ricardo; Martinez Agirre, Manex; Berasategi Arostegi, Joanes; Penalba, Markel; Bou-Ali, M. Mounir; Shevtsova, Valentina (Elsevier, 2023)

In transportation applications, filling high pressurised hydrogen tanks within a few minutes implies a fast and large temperature increase that can compromise the structural integrity of the storage system and the safety ...

Effect of near beta-transus forging parameters on the mechanical and microstructural properties of Ti-6Al-4V: Application to hammer forging

Agirre, Julen; Erice, Borja; Arrese Irazabal, Peio; GALDOS, Lander (Materials Research Forum LLC., 2023)

Ti-6Al-4V is a widely employed material in the aerospace, power generation and bioengineering industries due to its low density, excellent corrosion resistance and outstanding mechanical properties. Hammer forging is one ...

Effect of Post-Processing Treatment on Fatigue Performance of Ti6Al4V Alloy Manufactured by Laser Powder Bed Fusion

CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (MDPI, 2023)

Fatigue properties of parts are of particular concern for safety-critical structures. It is well-known that discontinuities in shape or non-uniformities in materials are frequently a potential nucleus of fatigue failure. ...

The effect of small perturbation on dynamics of absorptive LiBr–water solution

Fernandez de Arroiabe, Peru; Martinez Agirre, Manex; Bou-Ali, M. Mounir; Shevtsova, Valentina (AIP Publishing, 2024)

In a binary solution of lithium bromide–water, even a small disturbance in the initial homogeneous mass fraction at the absorbing interface has profound effects on the entire system dynamics. This perturbation of absorption ...

Effect of surface integrity generated by machining on isothermal low cycle fatigue performance of Inconel 718

Madariaga, Aitor; Garay, Ainara; Esnaola, Jon Ander; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2022)

Critical aero-engine components such as turbine discs must withstand severe cyclic stresses, which can eventually lead to low cycle fatigue (LCF) failures. These components are made of difficult-to-cut alloys and machining ...

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 ...

Effect of the loading-rate and stress state on the constitutive modelling and fracture of 2205 Duplex stainless steel

Abedul Moreno, David; GALDOS, Lander; Sáenz de Argandoña, Eneko; Erice, Borja (Elsevier, 2024)

Shear cutting is a high-speed forming process where material separation is involved. The nature of the process leads to high strain rates and temperatures on the sheared zone of the material subjected to the operation. In ...

Effect of Tool Geometry and LCO2 Cooling on Cutting Forces and Delamination when Drilling CFRP Composites Using PCD Tools

Rodríguez Bogajo, Iñigo; Soriano Moreno, Denis; Ortiz-de-Zarate, Gorka; CUESTA ZABALAJAUREGUI, MIKEL; ARRAZOLA, PEDRO JOSE (Elsevier, 2022)

Lightweight materials like Carbon Fiber Reinforced Polymers (CFRPs) present certain challenges, mainly regarding the resultant surface integrity of the holes. Different techniques such as optimized tool geometries, machining ...

Effect of voids on the impact properties of Non-Crimp fabric carbon/epoxy laminates manufactured by liquid composite Moulding

Mendikute, Julen; Baskaran, Maider; Aretxabaleta, Laurentzi; Aurrekoetxea, Jon (Elsevier, 2022)

A great effort has been made to quantify the detrimental effect of voids on CFRP, nevertheless, the effect on impact properties has been barely studied and when it has been considered, it has always been for prepeg materials ...

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)
