Comparison between indirect methods to determine high-temperature texturesof parent phases

Two specific methods to determine the high-temperature textures of parent p hases are tested. These methods are based on the orientation relationship b etween the parent and the inherited phases, and require specific applicatio n conditions which are outlined. To check their reliabilities, the methods are tested on the texture of a beta titanium alloy which underwent the beta --> alpha phase transformation. A good agreement is obtained between both indirectly calculated beta textures and the reference one, classically meas ured. Thus, it can be concluded that in many cases it is possible to study high-temperature parent textures by these methods, without measuring the te xtures in situ with a specific attachment.
