Elementary Transformation and Deformation Processes and the Cyclic Stability of NiTi and NiTiCu Shape Memory Spring Actuators
TL;DR: In this paper, the authors studied the effect of alloy composition and processing on actuator stability during thermomechanical cycling and found that functional fatigue of binary NiTi and ternary NiTiCu (with 5, 75, and 10 at pct Cu) shape memory actuators results in an accumulation of irreversible deformation in martensite and austenite.
Journal ArticleDOI
Influence of aluminum and manganese concentration on the shape memory characteristics of Cu–Al–Mn shape memory alloys
U.S. Mallik,V. Sampath +1 more
TL;DR: In this paper, a linear regression analysis was performed on four sets of Cu-Al-Mn shape memory alloys, in the range of 10-15% of aluminum and 0-10% of manganese, by ingot metallurgy.
Journal ArticleDOI
Effect of composition and ageing on damping characteristics of Cu–Al–Mn shape memory alloys
U.S. Mallik,V. Sampath +1 more
TL;DR: In this paper, the damping behavior of the alloys was studied using a dynamic mechanical analyzer and it was shown that damping capacity increases with an increase in the aluminum content when the Cu/Mn ratio or amount of manganese is maintained constant.
Journal ArticleDOI
Influence of quaternary alloying additions on transformation temperatures and shape memory properties of Cu–Al–Mn shape memory alloy
U.S. Mallik,V. Sampath +1 more
TL;DR: In this article, a ternary shape memory alloy with different amounts of quaternary elements Zn, Si, Fe, Pb, Ni, Mg, Cr and Ti were added to the base alloy.
Journal ArticleDOI
Processing and property assessment of NiTi and NiTiCu shape memory actuator springs
C H Grossmann,Jan Frenzel,V. Sampath,V. Sampath,T. Depka,A Oppenkowski,Christoph Somsen,Klaus Neuking,Werner Theisen,Gunther Eggeler +9 more
TL;DR: In this paper, the mechanical and functional properties of the wires are investigated in the stress-strain-temperature space, and functional fatigue testing of actuator springs is briefly described and preliminary results for NiTi and NiTiCu actuator spring are reported.
