Abstract Based on the theory of X--ray stress measurement, a method of measurement
and representation for the inter--phase stress of double--phase material
was established. The systematic error of the instrument has been effectively reduced by the difference between diffraction angles of two phases. The inter--phase stress of an actual material (SiCp/6061Al composites) was measured, and it was verified
that this method has a high measuring precision.
