Abstract: Semisolid Sn-Bi alloy slurry can be obtained by mechnical stirring technology.On the basis of the condition tests of stirring speed and shear time,the microstructure and mechanics properties of semi-solid alloy were studied by optical microscopy and universal testing machine.Test results show that the optimal microstructure of semisolid Sn-Bi alloy can be obtained at shear time 10 min with fixed agitating rate 320 r/min,at the temperature of 145 ℃ or so,and the smaller and nearly rounded solid p...
