Abstract

Magnetic shape memory alloys demonstrate significant potential for harvesting waste mechanical energy utilizing the Villari effect. In this study, a few milliwatts of power output are achieved taking advantage of martensite variant reorientation mechanism in Ni{sub 51.1}Mn{sub 24}Ga{sub 24.9} single crystals under slowly fluctuating loads (10 Hz) without optimization in the power conversion unit. Effects of applied strain range, bias magnetic field, and loading frequency on the voltage output are revealed. Anticipated power outputs under moderate frequencies are predicted showing that the power outputs higher than 1 W are feasible.

Microstructural development inside the stress induced martensite variant in a Ti-Ni-Nb shape memory alloy

Zheng, Y.F. ; Cai, W. ; Zhang, J.X. ; ... - Acta Materialia

The microstructural development inside the stress induced martensite (SIM) variants in Ti-Ni-Nb alloy with various degrees of deformation have been revealed by electron microscopic observations. The orientation relationship between the SIM and the parent phase has been found: [1{bar 1}0]{sub M}{parallel}[11{bar 1}]{sub B2}, (001){sub M} 5{degree} away from (101){sub B2}. The lattice invariant shear of the SIM variants at the slightly deformed stage is dominantly (11{bar 1}) Type I twin. Besides the ordinary slip, the adjustment and development of the internal secondary twinning from (11{bar 1}) Type I twin to {l_angle}011{r_angle} Type II/ or (011) Type I twin, (001)compound twinmore »« less

Influence of the presence of pre-existing thermal [var epsilon]-martensite on the formation of stress-induced [var epsilon]-martensite and on the shape memory effect of a Fe-Mn-Cr-Si-Ni shape memory alloy

Federzoni, L. ; Guenin, G. - Scripta Metallurgica et Materialia; (United States)

At present, many investigations are done on Fe-Mn-based shape memory alloys because of their particularly good one-way type shape memory effect and their low cost. With addition of Cr and Ni, it is possible to reach a good corrosion resistance, which confers to this type of alloys a commercial significance. The shape memory effect is associated with the formation of stress-induced [var epsilon]-martensite by deformation of an austenitic ([gamma]) sample. The reversion by heating of the [var epsilon]-martensite provides the shape memory effect. It is generally admitted that the presence of thermal [var epsilon]-martensite before deformation has a negative influencemore »« less

Harvesting Mechanical and Thermal Energy by Combining ZnO Nanowires and NiTi Shape Memory Alloy

Radousky, Harry ; Qian, Fang ; An, Yonghao ; ... - Advanced Nanomaterials and Techologies for Energy Sector

In the expanding world of small scale energy harvesting, the ability to combine thermal and mechanical harvesting is growing ever more important. Here, we demonstrate the feasibility of using ZnO nanowires to harvest both mechanical and low-quality thermal energy in simple, scalable devices. These devices were fabricated on kapton films and used ZnO nanowires with the same growth direction to assure alignment of the piezoelectric potentials of all of the wires. Mechanical harvesting from these devices was demonstrated using a periodic application of force, modeling the motion of the human body. Tapping the device from the top of the devicemore »« less

Electron microscopy studies of twin morphologies in B19{prime} martensite in the Ti-Ni shape memory alloy

Nishida, M. ; Ohgi, H. ; Itai, I. ; ... - Acta Metallurgica et Materialia

Twins in the B19{prime} martensite in the Ti-Ni shape memory alloy have been investigated by conventional transmission electron microscopy (CTEM) and electron diffraction. The following five twinning modes were observed. The <011> Type II twin was dominantly observed among those and confirmed to be a lattice invariant shear since most martensite variants consisted of the <011> Type II twinning. The {l_brace}11{bar 1}{r_brace} Type I twinning was morphologically and characteristically divided into three types, i.e. a deformation twin, a variant accommodation twin and a lattice invariant shear. (100) and (001) compound twinnings were considered to be a deformation twin. The {l_brace}011{r_brace}more »« less

High resolution electron microscopy studies of twin boundary structures in B19{prime} martensite in the Ti-Ni shape memory alloy

Nishida, M. ; Itai, I. ; Ohgi, H. ; ... - Acta Metallurgica et Materialia

The boundary structure of the <011> Type II, {l_brace}11{bar 1}{r_brace} Type I, {l_brace}011{r_brace} Type I, (100) compound and (001) compound twins in the B19{prime} martensite in the Ti-Ni shape memory alloy was observed in the edge-on state by high resolution electron microscopy (HREM). The lattice images of the Type I and the compound twins exhibit the well-defined crystallographic features of those boundaries. Lattice image of the <011> Type II twin taken from the unique {eta}{sub 1} axis suggests that neither ledge nor step structures are present at the irrational boundary.
