Feasibility tests of PCT, DCT and s-3DXRD in Ni superalloys and martensitic steels

Samples will be tested for the feasibility of a combination of both DCT and s-3DXRD techniques in martensitic steels. Ni superalloys will be characterized by PCT for crack detection and DCT as feasibility tests.本数据集的样本将用于测试马氏体钢中DCT（Discrete Cosine Transform）与s-3DXRD（synchrotron three-dimensional X-ray diffraction，同步辐射三维X射线衍射）技术组合的可行性。镍基高温合金（Ni superalloys）将通过PCT（Penetrant Testing，渗透检测）完成裂纹检测，并借助DCT开展可行性验证测试。
