A principal requirement for biomedical alloys in device implantation is in vivo corrosion resistance, and optimal compatibility at the implant interface. In the context of materials science, biocompatibility is the ability of a material to assist a specific biological application and elicit an appropriate response, simulated in vitro or translated in vivo. The in vivo response of a device is de...
Recent experimental research indicates that superelastic shape memory alloy nickel–titanium (NiTi) is superior to stainless steel against wear and could be applied in tribological engineering. It is believed that the super wear resistance of shape memory alloys is mainly due to the recovery of the superelastic deformation. Our recent wear study indicates that wear rate is very sensitive to the ...
I. Szurman, R. Kocich, M. Kursa, VŠB – Technical University of Ostrava, Faculty of Metallurgy and Material Engineering, Ostrava – Poruba, Czech Republic The presented work is focused on the determination of elastic constants of selected alloys of the systems Ni-Ti and Ni-Ti-Cu with use of ultrasonic methods. Sample preparation was carried out using VIM in graphite crucible in combination with p...
Increasing the strength of metallic alloys while maintaining formability is an interesting challenge for enabling new generations of lightweight structures and technologies. In this paper, we engineer aluminium alloys to contain a hierarchy of nanostructures and possess mechanical properties that expand known performance boundaries-an aerospace-grade 7075 alloy exhibits a yield strength and uni...
Abstract In the current scenario, manufacturing industries faces difficulties during machining of engineering materials-metal based, having higher mechanical properties viz. strength, toughness and hardness through conventional methods. These problems include rapid tool wear, poor surface quality work piece material lower stock removal rate. EDM is a single prominent what more lucrative unconve...
We present a computational screening study of ternary metal borohydrides for reversible hydrogen storage based on density functional theory. We investigate the stability and decomposition of alloys containing 1 alkali metal atom, Li, Na, or K (M(1)); and 1 alkali, alkaline earth or 3d/4d transition metal atom (M(2)) plus two to five (BH(4))(-) groups, i.e., M(1)M(2)(BH(4))(2-5), using a number ...
This chapter describes different rapidly solidified processing routes of soft magnetic alloys and their properties and applications in different areas. Section-2 explains the details of process mechanism. The functions of different alloying elements are discussed with the alloy design of soft magnetic alloys in section-3. The structureproperty correlation is described in section-4. Section-5 hi...
Two high corrosion resistant super-alloys, alloy 800H and 625, were evaluated for compatibility with molten nitrate salts at 565 °C under air atmosphere since these super-alloys are possible candidates the manufacturing of solar receivers in CSP tower technology. Both alloys tested two different grades to identify how impurities final mixture affect damage. Accordingly, a technical grade salt (...
