Give detail.The following is a backscattered electron image of a sample of nickel alloy particles that were embedded in a resin, cut, and then polished to reveal the internal structure of the particles. From the image, explain whether you think the alloy has uniform composition or whether it is segregated into phases of different compositions. The resin used for embedding is an electrical insulator. How should such samples be treated before they are examined by SEM?
