The invention discloses an endogenous rapid test method for
tellurium brittleness sensitivity of a high-
nickel alloy. The method comprises the following steps that S1,
tellurium elements are added into the high-
nickel alloy through a
smelting method, and a base material with
tellurium atoms preset inside is obtained; s2,
processing and forming the base material into a tellurium-containing sample, and carrying out
solid solution treatment on the tellurium-containing sample, so that tellurium atoms are completely and uniformly dissolved in the matrix
dot matrix; s3, carrying out aging treatment on the tellurium-containing sample subjected to the
solution treatment, and driving tellurium atoms subjected to
solution treatment in a matrix to migrate to a
grain boundary and form a segregation layer; and S4, performing quantitative characterization on the tellurium
brittleness sensitivity of the tellurium-containing sample subjected to aging treatment through a mechanical test. Compared with the prior art, the method has the advantages that the damage state after long-time service is reproduced by changing a
physical model and utilizing endogenous atom short-
range migration, and the tellurium
brittleness sensitivity of the high-
nickel alloy can be accurately, quantitatively, safely and efficiently tested and evaluated.
