Effect of precipitates on the stress–strain behavior under compression in polycrystalline Ni–Fe–Ga alloys

Effect of thermal treatments on the structural and magnetic transitions in melt-spun Ni-Fe-Ga-(Co) ribbons

“…On the other hand, repeated DSC scans produce an important decrease of the crystallite size. This may be due to the intragranular γ phase precipitates reducing the size of the transformable phase in the grains, as observed also in the case of bulk alloys [25].…”

Thermal characteristics of Ni–Fe–Ga–Mn and Ni–Fe–Ga–Co ferromagnetic shape memory alloys

“…The DSC peak temperatures are presented in Table 1 and compared with those obtained for the ternary alloys reported in Ref. [22], together with the L2 1 -B2 orderdisorder transition temperatures and the Curie points. From the results the following can be concluded:…”

“…Values corresponding to the ternary compounds reported in Ref. [22] are also included. not cause any microstructural change or heterogeneity in composition.…”

Effect of ambient temperature on compressibility and recovery of NiTi shape memory alloys as static seals

“…Once exceeding the s cr , the SIM transformation occurs and the deformation precedes by martensite variant reorientation and detwinning mechanisms. 22,30 In the situation, the deformation of the SIM in NiTi alloys is dominated. When unloading at the low stress, the reverse transformation takes place and martensite is back to the parent austenite at this stage.…”
