增材制造

增材制造(AM)是一个快速发展的领域,EBSD在其中发挥着重要作用。多种制造高性能材料的新方法的发展导致微观组织与更传统的制造工艺有很大的不同。这些微观组织需要进行表征,以便研究人员了解AM工艺参数对最终部件的物理性能的影响。EBSD是微观组织表征的理想技术,它提供了关于晶粒结构、相分布、织构、晶界性质和局部应变的信息。

EBSD在增材制造中的应用实例包括:

Evaluating parent grain reconstruction in Titanium using high temperature in-situ EBSD

Learn how parent grain microstructures can be reconstructed from low temperature EBSD analyses using AZtecCrystal. Here, the reconstruction results for a Titanium sample are tested using in-situ EBSD analyses of beta-Ti collected at >900 °C using a new type of high temperature phosphor screen. The results indicate an excellent agreement between the as-measured and reconstructed beta-Ti microstructures.
