%J 金属学报 %D 1986 %I %X The pole figure and inverse pole figure of the hydrostatically extruded Zr-2.5%Nb alloy tube with various Q values (the reduction ratio of wall thickness to diameter) were examined by X-ray diffration. It is resulted that the texture parameter, V_48 is related linearly to Q value. The texture gradient along the direction of tube wall thickness seems to be no appreciable. When the Q value changes from 0.2 to 2.59, the hydride is distributed into a circular direction via radial, and the corresponding texture parameter V_48 decreases from 0.53 to 0.28.The circular hydride distribution may be re-orientated under circular tensile stress after cyclic heat-treatment. The threshold of the stress re-orientaton of hydrideis rather high for tube with radial basal pole texture. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=AB188D3B70B071C57EB64E395D864ECE&jid=B061E1135F1CBDEE96CD96C109FEAD65&aid=1FE6743DD4FD14C7E8E093B0178F7F70&yid=4E65715CCF57055A&vid=BC12EA701C895178&iid=94C357A881DFC066&sid=E22B6B8FE86DD8F9&eid=769BD58726D66E7D&journal_id=0412-1961&journal_name=金属学报&referenced_num=0&reference_num=1
