Experimental Research on Ultrasound Cast-Rolling Lead Alloy Strip

Abstract:

With the ultrasound was put into the experiment of cast-rolling lead alloy strip, it broke the dendrite structures and enhanced the under-cooling by the effect of cavity and acoustic streaming. The microstructure comparison of ultrasound and general cast-rolling shows that: The grain size of general cast-rolled lead strip is big; the grain boundary is coarse and the organization structure is uneven. However, the grain structure is refined, smaller grains and uniform organization structure is acquired with ultrasound treatment. Besides, the mechanical properties test results of the two kinds lead alloys shows that the ultrasound cast-rolling lead alloys are better than general cast-rolling. The tensile strength, yield strength and elongation of ultrasound cast-rolling lead strip are increased by 11.30%, 22.15% and 21.74% than that of general cast-rolling lead strip.
