| titleOfInvention | A kind of analysis method of refractory elements in DD6 single crystal alloy |
| abstract | The invention relates to the technical field of metallurgical analysis, in particular to a method for analyzing refractory elements in a DD6 single crystal alloy, comprising the following steps: (1) using a certain proportion of hydrochloric acid-nitric acid-hydrofluoric acid mixed acid as a digestion agent, using peroxide Using hydrogen as oxidant and tartaric acid as complexing agent to pre-treat the single crystal alloy sample to obtain the sample solution to be tested; (2) prepare a series of W, Ta, Hf, Re elements and blank standard solutions based on Ni element; (3) The standard solution is measured by ICP-OES to obtain the calibration curve of the signal intensity and the concentration of each element; (4) ICP-OES is used to measure the sample liquid to be tested, combined with the calibration curve to obtain W, Ta, The contents of Hf and Re elements were further converted into the contents of W, Ta, Hf and Re elements in the single crystal alloy. The analysis method has short analysis period, low cost, high accuracy and good precision. |
