in the semi-solid range. The used rotational rheometer is characterized by a concentric cylinder measuring device. Rotational speed and momentum are measured at the rotating rod. Both rod and cup... carrier, to prevent the oxidation of the sample surface. The temperature is monitored by a thermocouple placed at the bottom of the cup. The semi-solid alloy is generated in the rheometer by cooling down......
