Summary: | The invention provides a method for measuring the thermal deformation dynamic precipitation volume fraction of an aluminum alloy in situ, and belongs to the technical field of metal material structures and characterization. The method comprises the following steps: calculating the initial resistivity of a to-be-measured sample before deformation through control parameters measured from the to-be-measured sample by in-situ measurement equipment; controlling the to-be-measured sample to perform constant-rate thermal deformation according to the sample parameters and the control parameters of the to-be-measured sample, collecting the control parameters in the deformation process through in-situ measurement equipment, and calculating the resistivity corresponding to the measured sample according to the control parameters in the deformation process; and quantitatively calculating the volume fraction of the precipitated phase in the thermal deformation process of the to-be-measured sample based on the resistivity i |
