Hot Plane Strain Compression Testing of Aluminum Alloys



Plane strain compression is a versatile laboratory testing method for simulating industrial hot working operations such as plate and strip rolling. The deformation can be closely controlled to the required conditions of temperature and strain rate, and high strains can be achieved without instability. However, for accurate determination of flow stress, care must be taken with experimental procedure and the interpretation of the measured force-displacement data.

This paper reports the results of work carried out in three laboratories on samples of the same cast of Al-1% Mn alloy. In particular, the effects of spread and friction are analyzed as a function of initial specimen geometry. When consistent procedures are used it is shown that excellent reproducibility of flow stress data is obtained between laboratories. In deriving constitutive relationships, the importance of considering the effects of lubricant films, of deformational heating, and of heat transfer are clearly demonstrated.
