Abstract Scope |
Shape Memory Alloys (SMAs) undergo a solid-state phase transformation under the application of stress or temperature enabling multifunctionality. The current work employs advanced thermal analysis to qualitatively and quantitatively investigate the extent to which SMAs exhibit thermoelastic transformations. SMA based Adaptive material system has matrix that begets a shape memory transformation within a host structural hierarchy through a reversible solid-state martensitic phase transformation (MT). In this work, we discuss thermoelastic reversibility of phase transformations in additively manufactured NiTi SMAs deposited with varying pre-blended ratio of elemental Ni and Ti powder feedstock. Standard differential scanning calorimetry (DSC) analysis is used for confirming the thermal-induced phase transformation occurs and establishing the temperature ranges for a material to exhibit shape memory effect (SME) or superelastic effect (SE). This work establishes an experimental and theoretical framework to evaluate the composition dependence of energetic variables to characterize underlying thermoelastic phase reversibility. |
