Effect of Bi on the Microstructure, Mechanical Properties and Wear Resistance of Cu-Alloyed Ductile Iron

Key Points

• Enhanced wear resistance observed with bismuth inclusion in copper-alloyed ductile iron, showing significant improvements.
• Mechanical properties were assessed using tensile tests, revealing a notable strength increase by approximately 20% with bismuth addition.
• Microstructural analysis was conducted using scanning electron microscopy, highlighting phase distribution changes due to bismuth.
• Findings suggest that using bismuth can optimize performance in ductile iron alloys, with potential implications for industrial applications.
