This phenomenon is initiated on cooling and deformation, and performed thermally on heating and cooling, with which shape of material cycles between between original and deformed shapes in reversible way. Therefore, this behavior can be called thermoelasticity. The origin of this phenomenon lies in the fact that the material changes its internal crystalline structure with changing temperature Thermoelasticity is governed by thermal and stress induced martensitic transformations on cooling and stressing. Thermal induced martensite occurs along with lattice twinning and ordered parent phase structures turn into twinned martensite structures by means of lattice invariant shears on cooling, and these structures turn into detwinned martensitic structures by means of stres induced transformation with deformation. Lattice Twinning occurs in two opposite directions, \u003C110 > -type directions on the {110}-type plane of austenite matrix in self-accommodating manner and consists of lattice twins. The twinning occurs with internal stresses, while detwinning occurs with the external stresses. These alloys exhibit another property called superelasticity, which is performed by stressing and releasing materials in elasticity limit at a constant temperature in parent phase region, and shape recovery occurs instantly upon releasing, by exhibiting elastic material behavior. Superelasticity is governed by stress induced transformation by stressing and releasing materials at a constant temperature in parent phase region. Superelasticity is also result of the stress induced martensitic transformation and ordered parent phase structures turn into detwinned martensitic structure with stressing. The crystal structure cycles between detwinned martensite structures and ordered parent phase structure with stressing and releasing. Twinning and detwinning processes can be considered as elementary processes activated during the transformations.  Shape memory effect is performed in a temperature interval after first cooling and stressing processe,  whereas superelasticity is performed mechanically in a constant temperature in parent phase region, just over the austenite finish temperature. Deformation at different temperature exhibits different behavior beyond shape memory effect and superelasticity.\nCopper based alloys exhibit this property in metastable beta-phase region, which has bcc based structures at high temperature parent phase field. Lattice invariant shear is not uniform in these alloys and cause to the formation of complex layered structures, depending on the stacking sequences on the close-packed planes of the ordered lattice.\nIn the present contribution; x-ray and electron diffraction studies were carried out on two solution treated copper based CuZnAl and CuAlMn alloys. Electron and x-ray diffraction exhibit super lattice reflections. Specimens of these alloys were aged at room temperature, and a series of x-ray diffractions were taken at different stages of aging in a long-term interval. X-Ray diffraction profiles taken from the aged specimens in martensitic conditions reveal that crystal structures of alloys chance in diffusive manner, and this result refers to the stabilization.\nKey words: Shape memory effect, martensitic transformation, thermoelasticity, superelasticity, twinning and detwinning\nBiography\nDr. Adiguzel graduated from Department of Physics, Ankara Universit","cbCaikhYMmi3e2QU","https://ap.wps.com/l/cbCaikhYMmi3e2QU","docx",46936,"English","# Abstract\n## Thermoelasticity and martensitic transformations\n## Superelasticity and stress-induced behavior\n## Experimental methods and alloy aging results","[{\"question\":\"How does shape memory effect depend on temperature in shape memory alloys?\",\"answer\":\"Shape memory effect occurs after initial cooling and stressing, then follows thermally activated behavior during heating and cooling, cycling the material between original and deformed shapes reversibly.\"},{\"question\":\"What crystal-structure mechanisms govern thermoelasticity in these alloys?\",\"answer\":\"Thermoelasticity is governed by thermal- and stress-induced martensitic transformations, where cooling leads to lattice twinning and detwinning occurs under external stress during deformation.\"},{\"question\":\"What did the X-ray and electron diffraction studies show for CuZnAl and CuAlMn alloys?\",\"answer\":\"Both alloys exhibit superlattice reflections; long-term room-temperature aging with staged X-ray measurements shows that, in martensitic conditions, crystal structures change diffusively, consistent with stabilization.\"}]","Deformation-Temperature Dependent in Memory Behavior of Shape Memory Alloys | DOCX",1788175817]
