Tensile Properties in Semi-solid State of Aluminum Alloys and Their Testing Methods (Since 2000)

Abstract

  Predicting hot tearing during casting process using thermal stress analysis requires mechanical properties in the semi-solid state of alloys. This paper reviews the tensile properties in the semi-solid state of aluminum alloys from literatures reported since 2000 by following two perspectives. One is the application of mechanical properties to the constitutive equation, and the other is the effects of temperature history of test specimens on tensile properties in the semi-solid state and microstructure. We conclude that tensile test after partial solidification is more appropriate than that during partial remelting for hot tearing prediction via thermal stress analysis.
