X-ray energy disperslve analyses sbow that the rati0 of titanium to potassium in the interlayer ismuch higher than that of the whlsker K,o.6TlO,, and that titanium and p0tassium atoms of the whisker arepartly diss0lved into the matrix AI near the whisker. The lnterrace residual strains in the composite are determined in terms of the shifts of HOLZ llnes. To unlqueIy evaluate the Iattlce parameters and the lattice strainsfrom an experimentaI HOLZ line pattern, the pIane stress approximation is employed to reduce the numberof adjustable parameters in the optimization procedure. The results obtained with this method are in goodagreement with other works. The possible expIanations for the high von Mises effective stresses in the matrixnear the whisker are discussed.
