Addressing the strength-ductility trade-off in a thermomechanical-processed high entropy alloy
Radi, Amin; Işıl, Canay; Seyedmohammadi, Seyedveghar; Kim, H. S.; Yapıcı, Güney Güven (Elsevier, 2023-12-15)High entropy alloys (HEAs) have garnered significant attention due to their exceptional mechanical behavior. However, the influence of secondary phases and dislocation substructures has yet to be thoroughly investigated. ... -
Effect of a multi-phase structure on the damping response of a novel high entropy alloy
Işıl, Canay; Radi, Amin; Seyedmohammadi, Seyedveghar; Yapıcı, Güney Güven (Elsevier, 2022-12-01)In this study, dynamic behavior of a novel multi-phase high entropy alloy (HEA) was investigated. Thermo-mechanical processes containing an 80 % thickness reduction at room temperature rolling followed by annealing at 750 ... -
Effect of processing parameters on the phase transformation of a high temperature copper-based shape memory alloy
Seyedmohammadi, Seyedveghar; Yapıcı, Güney Güven (Springer, 2023-11)In the present study, the influence of the processing parameters on the transformation temperatures and microstructural evolution in a copper-based shape memory alloy was investigated. Five times remelting in identical ... -
Effects of aging on the microstructure and phase transformation behavior of cu-al-mn shape memory alloy
Seyedmohammadi, Seyedveghar; Radi, Amin; Yapıcı, Güney Güven (Trans Tech Publications Ltd, 2021)In the present study, the effects of artificial aging heat treatment on the transformation temperatures and hardness of Cu-Al-Mn shape memory alloy have been investigated. The aging processes have been performed on the ... -
On the low-cycle fatigue behavior of a multi-phase high entropy alloy with enhanced plasticity
Radi, Amin; Sajadifar, S.; Seyedmohammadi, Seyedveghar; Krochmal, M.; Bolender, A.; Wegener, T.; Niendorf, T.; Yapıcı, Güney Güven (Elsevier, 2023-08)A multi-phase non-equiatomic FeCrNiMnCo high entropy alloy (HEA) was fabricated using vacuum induction melting. Thermo-mechanical treatments consisting of cold rolling and annealing at 750 °C and 850 °C were employed to ...
