Experimental results indicate that the addition of Lanthanum can evidently improve the wettability and the microhardness of Ag-Cu-Ti solder alloy. Analysis results show that the increase in microhardness is related to the refining and uniform distribution of the intermetallic compounds. Proper content of Lanthanum added in Ag-Cu-Ti alloy solder can be controlled below 0.5% in mass percent.展开更多

文摘The effects of rare earth Lanthanum on the microstructure, the physical property and the microhardness of Ag-Cu-Ti solder alloy are studied. Experimental results indicate that the addition of Lanthanum can evidently improve the wettability and the microhardness of Ag-Cu-Ti solder alloy. Analysis results show that the increase in microhardness is related to the refining and uniform distribution of the intermetallic compounds. Proper content of Lanthanum added in Ag-Cu-Ti alloy solder can be controlled below 0.5% in mass percent.
