本文报告了 Mg-Sn-Mn-Si 合金中 Mn5Si3 沉淀的初步研究。透射电子显微镜研究表明,Mn5Si3 沉淀物呈板状,厚度约为 50 nm,宽度约为 200 nm。析出物和基体之间的取向关系(OR)不是唯一的,但所有测量的OR都遵循以下关系:g(1 0 -1 0)Mn5Si3//Δg1//Δg2,其中Δg1=g(2 -1 -1 0)Mn5Si3−g(0 0 0 2)Mg,Δg2=g(3 -1 -2 0)Mn5Si3−g(0 0 0 2)Mg。析出物形貌及其与基体的 OR 用 Δg 平行规则解释,表现出良好的一致性。
This paper reports a preliminary study of Mn5Si3precipitates in an Mg–Sn–Mn–Si alloy. The transmission electron microscopy investigation reveals that the Mn5Si3precipitates have a plate shape, approximately 50 nm in thickness and 200 nm in width. The orientation relationship (OR) between the precipitates and matrix is not unique, but all measured ORs obey the following relationship: g(1 0 −1 0)Mn5Si3//Δg1//Δg2, where Δg1=g(2 −1 −1 0)Mn5Si3−g(0 0 0 2)Mg, Δg2=g(3 −1 −2 0)Mn5Si3−g(0 0 0 2)Mg. The precipitate morphology and their OR with the matrix are explained with a Δg parallelism rule, showing good agreement.
