The increasing demand for designing complex structures using Functionally Graded Material boosts the research on reliable joining processes. For several industrial applications in automotive, tooling, and petrochemical industries, of a stainless steel with low-alloy is often required to obtain variation mechanical corrosion properties when different parts same structure are subjected working conditions. Welding challenging operation because it not easy control microstructure welded joint...
Intermetallic titanium aluminides have attracted considerable industrial interest for aero and automotive applications owing to their specific strength. These alloys are candidates high-temperature such as turbine blades turbocharger wheels. In this work, the mechanical behaviour of an as-cast Ti–47Al–3Cr–3Nb (at.-%) alloy was studied. Four-point bending tests were performed determine properties at both room high temperatures. Microhardness Young's modulus evaluated by dynamic indentation...
In this work selective laser melting was successfully utilized to produce 316 stainless steel bulk specimens. Although technology provides many advantages compared conventional shaping processes, little residual porosity may be a problem for some applications where high strength is required. The objective of determine, through data analysis, mechanical and metallographic comparison between thin sheets made by using different manufacturing technologies: Cold rolling additive manufacturing....
γ -TiAl based intermetallic alloys have attracted broad attention as a potential candidate for high-temperature structural applications. A careful selection of their composition and microstructure allows to obtain an interesting combination oxidation resistance, creep resistance high temperature strength specific Over the years, several complex manufacturing methods been used producing TiAl parts. In this work blades produced by means investment casting. The analyses different production...
γ-TiAl has been a hot topic of research for more than few decades now, since it is potential candidate high temperature structural applications. In this paper, dispersion strengthening γ based TiAl alloy, produced by means centrifugal casting, performed to increase its mechanical properties beyond those standard alloys. After careful selection the alloy composition on desired properties, several samples were investment casting. This work focused effect Al2O3 nano- and micro-dispersoids...
The Al 7050 alloy is an Al-Zn-Mg-Cu-Zr having good mechanical properties. This has been developed in order to overcome stress corrosion cracking problems that characterise 7xxx alloys. Despite widely used for aerospace applications, it can be subjected crack initiation and propagation during the manufacturing process. In this work cracked components have analysed identify possible causes of formation such as coarse intermetallic phase presence, voids or wrong machining processes.
The structural integrity of mechanical components is assessed by FBG sensors in many industrial fields. sensor has a relevant application at very high or low temperatures. To avoid the variability reflected spectrum and properties degradation sensor, metal coatings have been used to guarantee grating’s extreme temperature environments. Particularly, temperatures, Ni could be suitable selection as coating improve features sensors. Furthermore, it was demonstrated that high-temperature...
