摘　　要：采用X射线衍射法研究一种快速而准确地测定3104冲压铝板塑性应变比r值的技术。根据铝板的织构组分和极图的对称性可以大幅度地减少极图数据的检测量,利用X射线面探测可以快速记录所需织构组分的关键数据,进而计算出正态分布各织构组分的体积分数。利用初始单系滑移模型和{123}〈634〉织构组分体积分数可以快速而准确地计算出3104铝合金板的应变比(r)值,并兼顾到非织构因素的影响。A rapid and accurate determination technology on Lankford parameter r of deep drawing 3104 aluminum sheets was investigated. The amount of pole figure data measured reduced drastically because of the pole figure symmetry. The necessary pole figure data were collected fleetly by the X-ray area detectors, the volume fraction of the texture components in G aussian forms were obtained. According to the volume fraction of the { 123 } 〈 634 ） texture, the r value of the 3104 aluminum sheets was calculated rapidly and accurately based on the initial single slip model, while some other effect factors beside texture were also included.
