The Fourier coefficients of the X‐ray diffraction line profiles from an ordered face‐centred tetragonal ( L 1 0 ) structure such as MgIn or CuAu have been calculated assuming the presence of twin and incoherent boundaries on (101). It is found that reflection components with ( h − l ) = 0 are not affected by twinning on (101). The theoretical expression for the effective particle size is compared with some measured particle sizes for cold‐worked MgIn.
