Effects of trace Sr additions on texture of Al-Mg-Si-Cu alloy sheets were analyzed by means of ODF method （oriented distribution function）.The results indicate that the samples without Sr are mainly composed of rotating cubic texture and gace texture

where the contents are 21.245% and 38.773%

respectively.The change of the samples with 0.033% Sr addition in texture feature can be neglected

compared with sample without Sr addition

and the texture contents are slightly decreased

where rotating cubic texture and face texture reach 18.665% and 35.553%

respectively

meanwhile

maximum orientation density occurs in {011}<211>.However

the samples with 0.093% Sr exhibits distinctly change in texture features

where rotating cubic texture and face texture are drastically decreased to 0.019% and to 1.133%

respectively

and maximum orientation density appears in {112}<111>.
