1、 Scope of use

The DJ-60 infinite distance research grade inverted metallographic microscope adopts excellent infinite distance optical system and modular functional design concept. After upgrading the system, polarization observation, bright field observation and other functions can be achieved. The compact and stable integrated main body design fully embodies the requirements of microscope operation stability. The idealized design of the instrument makes operation more convenient and space more extensive. Suitable for metallographic structure analysis and microscopic observation of surface morphology, it is an ideal instrument for research in metallurgy, mineralogy, and polymer materials science.

2、 System Introduction
The DJ-60 infinite distance research grade inverted metallographic microscope has an image output system. Traditional optical microscopes can be organically combined with computer computers (digital cameras) through photoelectric conversion. Not only can microscopic imaging be observed through eyepieces, but real-time images can also be directly observed and captured through computers or digital cameras, and the required images can be directly photographed, saved, and printed. Metallographic microscope computer type (DJ-60C type), professionally configuredIndustrial CameraConnect to a computer and use metallographic analysis software to perform metallographic module analysis and grading, and automatically generate reports. The DJ-60 metallographic microscope is equipped with a digital metallographic microscope (DJ-60D type) for users who are not convenient to access computers. It takes metallographic structure images directly through a digital camera or DSLR camera, and later imports them into a computer for metallographic analysis and grading reports using metallographic analysis software.

4Introduction to the functions of metallographic microscope

1. Automatic metallographic analysis function

The DJ-60 inverted metallographic microscope can be combined with the latest metallographic image analysis software developed by Yuanren Testing, and can be used as a professional instrument for metallographic analysis of materials such as cast iron (gray mouth, ductile iron) and cast steel. The system adopts the latest computer and information technology, integrates digital imaging devices and computer-aided metallographic analysis software, directly obtains metallographic images from the microscope and stores them in digital image file format on the computer. The system further processes and analyzes the images to calculate the required detection parameters, and can print and output the detection results in the form of a report.

Metallographic microscope analysis technology can systematically measure and evaluate results quickly and accurately, in compliance with national standards (GB) and other relevant industry standards (JB/YB/HB/QC/DL/DJ/STM, etc.). The system has a completely Chinese interface (English version can also be selected), which is concise, clear, and easy to operate. After simple training or reference to the user manual, it can be operated freely. And it provides a quick method for learning metallographic knowledge and popularizing operations.

The system includes the following main functions:

Image editing software: more than ten functions including image acquisition, image storage, etc;

Image software: more than ten functions such as image enhancement and image overlay;

Image measurement software: dozens of measurement functions such as perimeter, area, and percentage content;

Output methods: data table output, histogram output, image printing output.

Specialized metallographic software package:

◇ Grain size measurement rating (grain boundary extraction, grain boundary reconstruction, single-phase, two-phase, grain size measurement, rating);

Measurement and rating of non-metallic inclusions (including sulfides, oxides, silicates, etc.);

Measurement and rating of pearlite and ferrite content; Measurement and rating of graphite spheroidization rate of ductile iron;

Measurement of decarburization layer, carburization layer, and surface coating thickness;

Measurement of phase area in ferritic and austenitic stainless steels;

Analysis of primary and eutectic silicon in high silicon aluminum alloys;

Analysis of titanium alloy materials, etc;

◇ Contains metallographic diagrams of nearly 200 commonly used metal materials for comparison, suitable for the requirements of metallographic analysis and inspection in the vast majority of units;

Given the continuous increase in new materials and imported grade materials, materials and evaluation standards that have not yet been entered into the software can be customized and entered.
