Effect of Boron Content and Cooling Rate on the Microstructure and Boride Formation of β-Solidifying γ-TiAl TNM Alloy
(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 ... -
A novel forming technique to coforge bimetal components into complex geometries
(Elsevier Ltd., 2020)The novel Near Solidus Forming process has been used to coforge stainless steel 304 to encapsulate a core of 42CrMo4 steel in Stainless 304 in the form of a complex spindle. The forging was achieved with a force of 280 t, ... -
Thermophoresis as a technique for separation of nanoparticle species in microfluidic devices
(Elsevier Masson SAS, 2020)This paper presents numerical studies of thermophoresis approach for separation of nanoparticles in liquid media. We simulated the thermophoresis process to test it as a method of separation of particles in suspension. At ... -
Does employee participation matter? An empirical study on the effects of participation on well-being and organizational performance
(Springer-Verlag GmbH, 2020)Employability, talent and/or motivation of people can be a source of sustainable competitive advantage; difficult for competitors to imitate. The involvement of people, and more specifically employee participation, has ... -
An analytical approach to calculate stress concentration factors of machined surfaces
(Elsevier Ltd., 2021)Machining operations affect the properties of the final surface layer, and these can impact on its functional per- formance, particularly on fatigue behaviour. Among the properties of the machined surface, surface topography ... -
Surface Integrity When Machining Inconel 718 Using Conventional Lubrication and Carbon Dioxide Coolant
(Elsevier Ltd., 2020)Surface integrity induced by machining process affects strongly the performance of functional products, for instance, the fatigue life as well as the resistance to stress corrosion cracking. Consequently, it is relevant ... -
