Problems solved by technology

[0004] At present, domestic metallographic microscopes have installed camera devices above the eyepieces for the convenience of recording and observation. However, most of these metallographic microscopes are for room temperature observation, and their functions are relatively single. The heating temperature of most high-temperature metallographic microsc

Abstract

The invention relates to the technical field of metalloscopes, in particular to a high-resolution high-temperature metallographic structure analyzer which comprises a metalloscope equipped with a digital camera head, a hot stage, a cooling water circulation system of a window, a cooling water circulation system of a warm stage upper cover and a microcomputer embedded with an image analysis system. The analyzer is characterized in that the signal output end of the digital camera head is connected with the signal input end of the microcomputer, and the outer wall of the hot stage is respectively provided with a cooling water inlet, a liquid nitrogen cooling opening, a vacuum interface, a heating power supply interface, a thermocouple interface, a cooling water outlet and a reserved function interface. Compared with the prior art, by the invention, cooling speed and heating speed can be shown by numerical values and can be controlled more visually and conveniently; and in addition, the flow rate of the cooling water can be controlled in an intelligent way. The internal vacuum degree of the hot stage of the device can reach 10-3Pa, which can prevent a metal sample from being oxidized at high temperature. The reserved function interface of the device greatly widens the application scope of the high-temperature metalloscope.

Description

[technical field] [0001] The invention relates to the technical field of metallographic microscopy, in particular to a high-resolution high-temperature metallographic structure analyzer. [Background technique] [0002] The 20th century was a period of extensive development of vacuum technology. Huge developments have been made in the acquisition, measurement and maintenance of vacuum, which has laid a reliable foundation for the application of vacuum technology in laboratories and industrial practices. Behavior at high temperature has opened up broad development prospects, and gradually formed a new research technology - high temperature metallographic technology. The application of high-temperature metallographic technology will gain a new understanding of many processes that occur when metals are heated and cooled. The main equipment of high-temperature metallographic technology is a high-temperature metallographic microscope. [0003] A major symbol of the development of...
