AI总结:

本研究通过织构断层扫描(TT)技术实现Ti-6Al-4V合金块体中微织构区域的无损3D表征,验证了其单轴数据采集与重建程序的有效性,并揭示了微织构区域的3D形状及与轧制方向的关联。

摘要:

本研究展示了通过织构断层扫描(TT)重建的Ti-6Al-4V合金立方样品的空间分辨织构和取向图。与需要“斑点”衍射图案的晶粒分辨3DXRD技术不同,TT可通过3D扫描过程中收集的连续衍射图案重建局部(体素化)取向分布函数(ODFs)。对同一样品在两种不同设置下扫描的重建结果,以及随后平行于样品一个表面的EBSD分析,显示出极佳的相互一致性,验证了此类材料的单轴数据采集和重建程序。重建揭示了多个微织构区域的存在及其3D形状,这些区域显示出α相的尖锐单峰织构,且这些区域的取向和空间排列与轧制材料的轧制方向、横向和法向有明确关联。

英文摘要:

In this study we present spatially resolved texture and orientation maps from a cube-shaped sample of Ti-6Al-4V alloy, reconstructed by means of texture tomography (TT). Unlike grain resolved 3DXRD techniques which require "spotty" diffraction patterns, TT can reconstruct local (voxelized) orientation distribution function (ODFs) from continuous diffraction patterns collected in a 3D scanning procedure. Reconstructions of the same sample, scanned in two different settings and subsequent EBSD analysis parallel to one of the sample faces show excellent mutual agreement and validate the single-axis data collection and reconstruction procedure for this class of materials. The reconstruction reveals the presence and the 3D shape of several micro-textured regions, showing a sharp unimodal texture of the $α$-phase with a clear link of the orientation and spatial alignment of these zones to the rolling, transverse and normal directions of the rolled material.
