Advanced Shape Memory & Superelastic Materials
Custom NiTi-X Ternary and quaternary systems engineered for tunable functional behavior
We specialize in the development of custom ternary and quaternary NiTi-X alloys (X = Cu, Hf, Co, and others) to precisely tune:
• Transformation temperature
• Force output
• Hysteresis width
• Fatigue performance
• Electrical behavior
Our lab and pilot-scale co-sputtering capabilities enable rapid iteration and validation of novel alloy compositions. By pairing alloy engineering with scalable deposition and structuring platforms, we deliver materials optimized for specific integration and performance environments.
Our engineered materials exhibit superelastic behavior, the shape memory effect, and elastocaloric response across microscale and macro-scale applications.
Overview
Nickel-titanium (NiTi) shape memory alloys are functional metals capable of recovering shape, generating force, and responding dynamically to temperature and mechanical loading.
Khanjur engineers NiTi and NiTi-X materials across multiple length scales using thin film manufacturing and precision laser structuring platforms to support tailored functional performance.
Scientific Foundation
Shape memory behavior arises from reversible martensitic phase transformations.
- Shape Memory Effect: thermal recovery of programmed deformation via thermal induced phase transformations
- Superelasticity: large recoverable strain under mechanical loading via stress induced phase transformations
- Elastocaloric Effect: thermo-mechanical energy conversion during phase transformation
Alloying with elements such as Cu or Hf enables tuning of transformation temperature, hysteresis width, fatigue performance, and mechanical response.
Khanjur’s Unique Capabilities
We tailor composition, thickness, geometry, and processing conditions to meet application-specific requirements, enabling materials engineered for force output, thermal response, compliance, and integration needs via our thin-film manufacturing processes.
We also offer a proprietary low-temperature laser structuring manufacturing of commercial NiTi strips, sheets, and foils that preserve the functional properties of the NiTi material to allow additional functionalities to arise by tuning the geometry.
