چکیده
Five high entropy alloys with shape memory effect or superelastic were prepared by cold crucible melting to understand the of their chemical composition on transformation temperatures. The microstructure and phases at room temperature investigated optical scanning electron microscopy. calorimetric study these is employed analyze reversible from austenite martensite determine temperatures five alloys. paper presents results several published works relating (HE-SMA). An experimental database has been built up influence different alloying elements related concentrations Ms (Martensite Start) HE-SMAs. equation identified using predict a alloy as function its weighted composition, which exhibits metallurgical solutioned treatment (ST) state specific mixing (ΔSmix/R) range.

Slip Resistance of Ti-Based High-Temperature Shape Memory Alloys
Titanium with Nb, Zr, and Ta alloying substitutions possesses high plastic slip resistance and high transformation strains upon bcc (b) to orthorhombic ða00Þ transformation. In the current study, we determine the critical resolved shear stress (CRSS) for slip in Ti alloyed for a wide composition range of Nb, Ta, and Zr. The CRSS is obtained with a proposed Peierls–Nabarro formalism incorporatin...

Application of Shape Memory Alloys in Seismic Isolation: A Review
In the last two decades, there has been an increasing interest in structural engineering control methods. Shape memory alloys and seismic isolation systems are examples of passive control systems that use of any one alone, effectively improve the seismic performance of the structure. Characteristics such as large strain range without any residual deformation, high damping capacity, excellent re...
متن کاملConfirming the Composition of Shape Memory Alloys by Microstructural Characterization
It is well known that the properties of shape memory alloys, such as binary Ni-Ti (nitinol), are very sensitive to composition.[1-3] Especially on the Ni-rich side of stoichiometry, the martensite/austenite phase transformation temperature decreases abruptly when Ni is increased only a few tenths of a weight percent.[4] In ternary high temperature shape memory alloys (HTSMAs) containing Pt, Pd,...
متن کاملShape Memory Alloys
THE TERM SHAPE MEMORY ALLOYS (SMA) is applied to that group of metallic materials that demonstrate the ability to return to some previously defined shape or size when subjected to the appropriate thermal procedure. Generally, these materials can be plastically deformed at some relatively low temperature, and upon exposure to some higher temperature will return to their shape prior to the deform...
