| titleOfInvention | A kind of preparation method of internal control standard sample for spectroscopic analysis of cast superalloy |
| abstract | The invention belongs to the technical field of chemical analysis of superalloys, and particularly relates to a preparation method of an internal control standard sample for spectroscopic analysis of cast superalloys. The method mainly includes the following steps: (1) determining the batching point of the alloy according to the element mass percentage range of the superalloy, and preparing a master alloy ingot by using a vacuum furnace for high temperature melt treatment; (2) using a directional solidification furnace to make the master alloy ingot A directional solidification sample is prepared by secondary remelting, and processed into a sample of a certain size; (3) The sample is subjected to a homogenization heat treatment to improve the uniformity of the composition. The invention obtains a sample with uniform and stable composition by controlling the temperature gradient G, casting temperature, drawing speed and other parameters at the front of the solidification interface during the directional solidification process, and the surface of the sample is processed to obtain an internal control standard sample. The method of the invention has the advantages of simple and easy realization, short period, uniform and stable components, high product qualification rate, and greatly reduces the component segregation degree of the samples prepared by the traditional method. |
