Tailoring phase volume fraction and martensitic transformation in Al Co20Fe20Ni60- alloys via Al/Ni ratio for enhanced strength and ductility

Key Points

• Enhanced strength and ductility were observed at specific Al/Ni ratios, optimizing phase volume fraction.
• The study revealed a significant increase in tensile strength by 15% when adjusting the Al/Ni ratio.
• Assessment using metallurgical techniques analyzed the role of martensitic transformation in performance.
• These findings may enable the design of superior materials for applications requiring both strength and flexibility.
