Abstract

The invention discloses a method for continuous metal cutting and metallographic in-situ display. The method includes the following steps: fixing a metal workpiece to be cut with a rotating fixture, performing high-speed rotation under the clamping, and selecting sandpaper for cooperation, The part to be cut of the metal workpiece is ground and stopped after a period of time; the present invention can display both the grain boundary and the second phase, which is very efficient for batch sample preparation, and can also observe the different parts of the bulk material. The microstructure has good adaptability to the refractory dual-phase alloy, and can quickly obtain relevant samples in batches, and it is relatively easy to obtain large-scale metallographic samples, which is of great significance for analyzing the metallographic structure of large components. , which solves the problem that the overall structure of the material is often not obtained due to the locality of the metallographic morphology, and it is inconvenient to continuously obtain the metallographic structure in large-scale production.

Description

technical field [0001] The invention relates to the technical field of metallographic structure inspection, in particular to a method for continuous metal cutting and metallographic in-situ display. Background technique [0002] Copper alloy is one of the main metal materials for electrical and thermal conductivity. Alloying is one of the common means of strengthening metal materials. The strength of copper alloy is mainly improved by adding other elements for alloying. There are two main forms of existence: one is that an element enters the atomic lattice gap of the base metal, or replaces the base metal atoms by substitution to form a so-called solid solution; the other is that the added element exists in the matrix in the form of a second phase. . Formation of solid solution strengthening or second-phase strengthening, between the two, second-phase strengthening is often the more common strengthening method. [0003] Copper alloys usually use the second phase strengthen...
