%X The dispersoid phase Al_(20)Cu_2Mn_3 in a 2024 Al alloy is commonly composed of twins,An ob-servation of corresponding high resolution image shows that the twin boundary plane is a glideplane other than mirror one.Two neighbouring components of twins are not symmetry of re-flection or rotation,but of glide reflection.The“diamond”glide plane is(101)and the glidevector is(1/4)(-).Components of twins in the phase take shape of prism with thelongitudinal edge being parallel to010]and side faces being{101}and{100}.
