Abstract
X-ray energy dispersive analyses show that the ratio of titanium to potassium in the interlayer is much higher than that of the whisker K2O·6TiO2, and that titanium and potassium atoms of the whisker are partly dissolved into the matrix Al near the whisker. The interface residual strains in the composite are determined in terms of the shifts of HOLZ lines. To uniquely evaluate the lattice parameters and the lattice strains from an experimental HOLZ line pattern, the plane stress approximation is employed to reduce the number of adjustable parameters in the optimization procedure. The results obtained with this method are in good agreement with other works. The possible explanations for the high von Mises effective stresses in the matrix near the whisker are discussed.
