| Abstract: | A improved equipment was designed to test the apparent viscosity of semisolid alloy slurry since many shortcomings appeared in previous devices. Measurements based on the theoretic calculation formula were taken, all components were reasonably assembled, and accurate and stable testing was conducted. The semisolid alloy is prevented to be oxidized, high solid fraction alloy is able to deal with, and semisolid alloy samples can be obtained conveniently. Apparent viscosity testing and metallurgical structure ... |
