Ultra-Fine Grained Alloy Material
Thermomechanical processing has been applied to selected alloys to produce enhanced ductility. A fine-grained microstructure at high ductility was produced in eutectic lead-tin and lead-antimony. Melt-extracted fibers of lead-antimony were also produced and exhibited high ductility. Microstructural analyses were performed using optical and X-ray methods. It was concluded that ductility enhancement was due to the presence of large quantities of metastable, disordered grain boundary material.
