1Instrument Introduction

YJ-360The research-oriented infinite distance reflection metallographic microscope adopts an 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. Suitable for observing transparent and opaque substances in various electronic processing and casting industries, Materials such as metals, ceramics, integrated blocks, printed circuit boards, liquid crystal panels, films, fibers, coatings, and various others are also suitable for observation and analysis in agriculture, forestry, animal husbandry, fisheries, and scientific research departments.

2、 Image output system

metallurgical microscopeThe YJ-360 model has an image output system. Traditional optical microscopes can be organically combined with computer computers (digital cameras) through photoelectric conversion, withoutOnly microscopic imaging can be observed through the eyepiece, and real-time images can be directly observed and captured through a computer or digital camera. The required images can be directly photographed, saved, and printed. Metallographic microscope computer type (YJ-360C type), equipped with a professional industrial camera, connected to a computer, and combined with metallographic analysis software, can perform metallographic module analysis and grading, and automatically generate reports. The YJ-360 metallographic microscope is equipped with a digital metallographic microscope (YJ-360D 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

Metallographic microscope can be developed recently in conjunction with Yuanren TestingMetallographic image analysis softwareCombined, it 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, and obtains directly from the microscopeMetallographic imageAnd stored 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.
