Buch. Zustand: Neu. Neuware - A shape-memory alloy (SMA) refers to a type of alloy that deforms when cold but returns to its pre-deformation shape on being heated. The parts made from SMA are lightweight and solid-state alternatives for traditional actuators, such as motor, and hydraulic and pneumatic based systems. They are also useful for creating hermetic joints in metal tubing. The two most common SMAs are nickel-titanium (NiTi) and copper-aluminium-nickel. SMAs can also be made by alloying copper, iron, zinc and gold. SMAs exhibit varying shape-memory effects and the two most prevalent effects are one-way SMA and two-way SMA. The SMAs can be created through casting in which vacuum arc melting or induction melting is used. They have applications in various areas such as orthopedic surgery, aircraft and spacecraft, robotics, smartphone cameras, valves, optometry, medicine, and dentistry. This book presents the researches that have transformed the understanding of the properties and applications of shape-memory alloys. It is appropriate for students seeking detailed information in this area of metallurgy as well as for experts.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book, shape memory alloys made from Cu Al Ni have been prepared using powder metallurgy technique with 13%wt Al and 4%wt nickel which is the master alloy , having different alloying elements such as Cr, Nb and Ta in ( 0.3,0.6 and 0.9%wt ) additions . After mixing of powders , Disc samples with 14mm diameter and 5 mm thickness as well as cylindrical samples with 11mm diameter and 16.5mm length have been prepared at 650 MPa as suitable compacting stress according to porosity and apparent density results. Sintering in vacuum tube furnace for all prepared specimen has been achieved using two stage sintering temperature 500ºC for one hour and the second in 850ºC for five hours. Physical and mechanical tests have been done after sintering which covered apparent density and porosity, X-ray diffraction and hardness, compression strength ,dry sliding wear and shape effect. Microstructure characteristics were also observed with optical microscope and scanning electron microscope with Energy Dispersive X-ray Spectrometry (EDX).Finally Differential scanning calorimeter (DSC) was used to determine phase transformation temperature for all alloys with additive . 116 pp. Englisch.…

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This work investigates the influence of inoculants and the directional solidification process on the microstructural and mechanical properties of shape memory Cu-Al-Mn alloys. The alloys were produced by melting in an induction furnace, with controlled addition of inoculant elements, and subjected to directional solidification, followed by appropriate heat treatments. Characterization was carried out using optical microscopy, scanning electron microscopy, X-ray diffraction and ultramicrohardness tests. The results indicate that the addition of inoculants promotes grain refinement and modifies microstructural morphology, while directional solidification contributes to preferential grain orientation and greater structural homogeneity. These changes are reflected in improvements in mechanical properties, especially in the increase in microhardness and in the stability of the martensitic phase associated with the shape memory effect. The results also show that the combination of inoculation and directional solidification is an efficient strategy for optimizing the mechanical and functional performance of Cu-Al-Mn alloys, increasing their potential for technological applications.…
