Abstract

The invention discloses an analytical method for quantitative evaluation of alloy element segregation in high-temperature alloy. The method includes: an energy dispersive spectrometer for determining main components of a grain boundary precipitate; by a spectrum area scanning function of an electronic probe, distinguishing grain boundary distribution and transgranular distribution of corresponding elements; extracting data of an element area profile; analyzing the data, calculating grain boundary and transgranular element concentration distribution coefficients and drawing a graph of relation to finally realize quantitative evaluation of alloy element segregation in high-temperature alloy. By the analytical method for quantitative evaluation of alloy element segregation in high-temperature alloy, quantitative distinction of distribution of alloy elements at different grain boundary and transgranular positions of the high-temperature alloy can be realized without consumption of a great quantity of standard samples, and extensive application range and evaluation reasonability are realized.

Description

technical field

[0001] The invention belongs to the technical field of component analysis of high-temperature alloy materials, and relates to an analysis method for quantitatively evaluating the segregation of alloy elements in high-temperature alloys. Background technique

[0002] In order to improve the high-temperature strength, corrosion resistance and structural stability of alloys, the research on superalloys tends to diversify the types and increase the number of alloying elements. Different alloying elements play different roles, such as solid solution strengthening, second phase strengthening and grain boundary strengthening and so on. The quantity, composition, size, distribution of various phases and the distribution of alloying elements at grain boundaries have a great relationship with the mechanical properties and corrosion resistance of superalloys. Therefore, the segregation law of alloying elements in superalloys is studied and predicted The state of segreg...
