Microstructure characterisation in metal powders by EBSD
We demonstrate how gas atomised copper powders can be effectively characterised using EBSD data collected with the latest high-speed Symmetry EBSD detector.
技术
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：
测量的微观组织（98% α-Ti）。
重构的β-Ti微结构

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.
Examine the role of electron microscopy as a powerful tool within the 3D printing process, See how to control the cleanliness of powder feedstock using automated particle classification with EDS as well as ensuring the quality of finished components using microstructural characterisation with EBSD.
Learn how to overcome challenges of in-situ heating experiments for EBSD & how the heating-rate effects the temperature recrystallisation mechanism. Explore how fast & sensitive CMOS EBSD allows the effect of cooling rates on nucleation of the room temperature phase to be measured.
In this webinar, where are joined by one of the developers of a new approach to parent grain reconstruction, Dr Hung-Wei (Homer) Yen, who will be discussing the importance of understanding parent microstructures in the steel industry.
