The results show that the deformation texture of 1420 alloy plate is enhanced with trace Er added in,and the enhancement of brass texture B{011}<211> is the most prominent,which is attributed mainly to the effect of Er on decreasing fault energy of 1420 alloy and the high interaction energy between Er and dislocation.
