Enhancing fatigue life of L12-strengthened multi-principal element alloy by tailoring grain boundary characteristics and precipitation

Key Points

• Fatigue life improvement is linked to tailored grain boundary characteristics and precipitation phenomena.
• Investigating the effects on fatigue life revealed improvements of up to 30% in multi-principal element alloys.
• Assessment of mechanical properties through tailored processing techniques was conducted across various compositional variations.
• Highlights the need for further exploration into grain boundary characteristics for broader applications.
