The application discloses a
test platform, a method and application for monitoring a
metal material heat treatment process in situ, wherein the
test platform comprises a sample environment
control system, a small-angle
neutron scattering
system, an electrical resistivity and temperature test
system and a comprehensive control and
collection system, the platform can perform in-situ macroscopic detection on
phase transition /
precipitation behavior of a
metal bulk material in a heat treatment process, is simple to operate, is widely applicable, can measure a temperature range of RT-1200 DEG C, can be additionally provided with a vacuum or a protective
atmosphere environment, test results are composed of two parts of electrical resistivity and small-angle scattering results, and mutual interference between the test results is effectively overcome, and the test results are more accurate and reliable. The method is suitable for obtaining relevant quantitative information of
precipitation behavior of a
metal material in a heat treatment process, and provides a novel and reliable in-situ detection and analysis technology for in-situ tracking and quantitative analysis of
phase transition or
precipitation behavior of a metal material in a heat treatment process.
