Abstract
Fusible alloys have the extreme importance because they are used in medical fields (armor and protective of radiation protection and nuclear reactors) and industrial such as (Solders- Bearing- warning devices, thermal switches and etc...). Therefore, the objective of this work was : first to understand the thermal behavior and physical properties and their relationship to the structural composition of the fusible alloys. Second, the production of alloys with low melting point and better physical properties for various industrial applications such as welding alloys with low melting point for the solder computer components and electronics, as well as bearing alloys with best physical properties for different industrial applications with environmentally friendly and other for protective radiation. To verify these aims five groups of fusible alloys contain most of its constituent elements as follows were studied. (1) Binary alloys of Bi-Pb, Bi-Sn and Bi-Cd.(2) Ternary alloys of Bi-Pb-Sn, Bi-Sn-Cd, Bi-Pb-Cd and Bi-Sn-Zn. (3) Quaternary alloys of Bi-Sn-Zn-In, Bi-Sn-Zn-Ag and Bi-Pb-Sn-Cd. (4) Penta alloys of Bi-Pb-Sn-Cd-Cu, Bi-Pb-Sn-Cd-Zn, Bi-Pb-Sn-Cd-Se, Bi-Pb-Sn-Cd-In, Bi-Pb-Sn-Cd-Al and Bi-Pb-Sn-Zn-In. (5) Hexa alloys of Bi-Pb-Sn-Zn-In-Ag and Bi-Pb-Sn-Cd-In-TiO2. Also melt spinning technique was used to prepare Bi75Pb25, Bi87.5Sn12.5, Bi87.5Cd12.5, Bi75Sn12.5Cd12.5, Bi62.5Pb25Cd12.5, Bi71-xSn25Zn4Agx (x= 0, 0.5, 1.5, 2.5 and 3.5 wt. %), Bi71-xSn25Zn4Inx (2, 4, 6, 8 and 10 wt. %), Bi50-xPb25Sn12.5Cd12.5Xx(X=0 or Cu or Se or In or Al or Zn and x= 2), Bi50Pb15Sn22In10X3 and Bi50Pb15Sn28In4X3(X=Cd or Zn), Bi50-xPb15Sn22Cd3In10(TiO2)x (x= 0.5, 1, 1.5).
