Title: Role of B19' martensite deformation in stabilizing two-way shape memory behavior in NiTi

Abstract

Deformation of a B19' martensitic, polycrystallineNi49.9Ti50.1 (at. %) shape memoryalloy and its influence on the magnitude and stability of the ensuing two-way shape memory effect (TWSME) was investigated by combined ex situ mechanical experimentation and in situneutron diffraction measurements at stress and temperature. The microstructural changes (texture, lattice strains, and phase fractions) during room-temperature deformation and subsequent thermal cycling were captured and compared to the bulk macroscopic response of the alloy. With increasing uniaxial strain, it was observed that B19' martensite deformed by reorientation and detwinning with preferred selection of the (1¯50)_M and (010)_M variants, (201¯)_B19' deformation twinning, and dislocation activity. These mechanisms were indicated by changes in bulk texture from the neutron diffraction measurements. Partial reversibility of the reoriented variants and deformation twins was also captured upon load removal and thermal cycling, which after isothermal deformation to strains between 6% and 22% resulted in a strong TWSME. Consequently, TWSME functional parameters including TWSME strain, strain reduction, and transformation temperatures were characterized and it was found that prior martensite deformation to 14% strain provided the optimum condition for the TWSME, resulting in a stable two-way shape memory strain of 2.2%. Thus, isothermal deformation of martensite was found to be amore »« less

Evolution of Intergranular Stresses in a Martensitic and an Austenitic NiTi Wire During Loading–Unloading Tensile Deformation

Journal Article Cai, S. ; Schaffer, J. E. ; Yu, C. ; ... - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

In situ synchrotron X-ray diffraction testing was carried out on a martensitic and an austenitic NiTi wire to study the evolution of internal stresses and the stress-induced martensite (SIM) phase transformation during room temperature tensile deformation. From the point of lattice strain evolution, it is concluded that (1) for the martensitic NiTi wire, detwinning of the [011](B19') type II twins and the {010}(B19') compound twins is responsible for internal strains formed at the early stage of deformation. (2) The measured diffraction moduli of individual martensite families show large elastic anisotropy and strong influences of texture. (3) For the austenitic NiTimore »« less

We investigated the effect of thermomechanical cycling on a slightly Ni(Pd)-rich Ni_24.3Ti_49.7Pd₂₆ (near stochiometric Ni–Ti basis with Pd replacing Ni) high temperature shape memory alloy. Furthermore, aged tensile specimens (400 °C/24 h/furnace cooled) were subjected to constant-stress thermal cycling in conjunction with microstructural assessment via in situ neutron diffraction and transmission electron microscopy (TEM), before and after testing. It was shown that in spite of the slightly Ni(Pd)-rich composition and heat treatment used to precipitation harden the alloy, the material exhibited dimensional instabilities with residual strain accumulation reaching 1.5% over 10 thermomechanical cycles. This was attributed to insufficient strengthening ofmore »« less

Texture evolution during nitinol martensite detwinning and phase transformation

Journal Article Cai, S. ; Schaffer, J. E. ; Ren, Y. ; ... - Applied Physics Letters

Nitinol has been widely used to make medical devices for years due to its unique shape memory and superelastic properties. However, the texture of the nitinol wires has been largely ignored due to inherent complexity. In this study, in situ synchrotron X-ray diffraction has been carried out during uniaxial tensile testing to investigate the texture evolution of the nitinol wires during martensite detwinning, variant reorientation, and phase transformation. It was found that the thermal martensitic nitinol wire comprised primarily an axial (1{sup ¯}20), (120), and (102)-fiber texture. Detwinning initially converted the (120) and (102) fibers to the (1{sup ¯}20) fibermore »« less

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

Journal Article 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

Effect of different stages of deformation on the microstructure evolution of Ti-rich NiTi shape memory alloy

Journal Article Tadayyon, Ghazal ; Centre for Research in Medical Devices ; Guo, Yina ; ... - Materials Characterization

The main objective of this work was to investigate the thermomechanical behavior and microstructural changes of a Ti-rich NiTi shape memory alloy (SMA). The microstructural and texture evolution of aged NiTi alloy at different degrees of deformation were elicited by transmission electron microscopy (TEM). An effort was made to correlate results obtained from the tensile test with results from microstructure studies. The undeformed sample reveals a self-accommodated morphology with straight and well defined twin boundaries. At different stages of deformation, diverse mechanisms were involved. These mechanisms include marstraining, detwinning accompanied by dislocation movement, and finally, severe plastic deformation, subdivision andmore »« less
