Study on Preparation and Mechanical Properties of Pb-RE Alloy for Copper Electrowinning AITranslate
Abstract AITranslate
The different types （Pb-Pr,Pb-Sm,Pb-Nd） and different RE contents （0.1%、0.5%、1.0%、1.5%、2.0%） of Pb-RE alloys were prepared by two-stage remelting,and the study was made on the influence rule of the content and type of rare earth element on the tensile strength and microstructure of the alloy. The results show that addition of Pr,Sm,Nd can improve the strength of the alloy in different level, and with the increase of content of rare earth elements the strength of the alloy can improve in different degree. The extent of the effect of RE elements on improving the tensile strength of the alloy goes as follows： Pr〉Sm〉Nd. Nd,Sm and Pb generate intermetaliic compound and precipitate on the grain interface,bene- ficial for the alloy strength improvement. Besides generating intermetallic compound,Pr can also refine alloy grains and prevent grain slip, as is also one of the most important factors to improve the tensile strength of the alloy.
