Metallographic diagram of Q235 steel (950℃ salt bath chromizing 6h)
Q235 steel is a common low-carbon alloy steel that is used in many applications. The mechanical properties of Q235 steel make it an ideal choice for various applications. At 950℃ salt bath tempering, Q235 steel undergoes a chromium precipitation process that takes 6 hours. This process can lead t......

polarized light interference contrast image
Polarization Interference Fringes
Polarization interference fringes are bands of light and dark strips produced when opposite linear polarizations of monochromatic light interfere. They are used to measure the optical retardation of transparent materials. These fringes can form in several ways. De......
Structural characteristics of polarized light microscope
Structure Characteristics of Polarizing Light Microscope
Polarizing light microscope is also known as an optical microscope. It is a polarizing microscope that uses specific optical principles according to the polarization characteristics of reflected light to observe the transparency and birefri......
Dual Beam Interference Microscope
Double Beam Interference Microscope
A double beam interference microscope is a machine which has been used in laboratories and research centres since the middle of the 20th century. It uses two coherent light beams, whose data can be analysed in order to determine the physical properties of a sam......

Carbonless BESizing Microscopy
Carbonless BESizing microscopy is a type of electron microscopy that is used to image the internal structure of materials. It is unique because it eliminates the need for carbon foils, which are traditionally used in conventional transmission electron microscopy, ......
Optical Structure of Phase Contrast Microscope
Optical structure of Compensating Microscope
Compensating microscope is an important instrument for metrology and physical measurements. Optical structure is the fundamental of a microscope, and how the microscope works also depends on its optical structure.
Optical structure of compensating mic......
thin film interference display tissue
Introduction
Interference is a phenomenon of waveoptics in which two or more waves from the same source meet at a common point, thereby producing a resultant wave whose amplitude is the sum or difference of the amplitudes of the individual waves.This phenomenon can be observed in wide range of ......
Metallographic identification of non-metallic inclusions
Metallographic Evaluation of Non-Metallic Inclusions
Introduction
Non-metallic inclusions (NMIs) are an unavoidable impurity in metals, which can have deleterious effects on material properties such as strength and toughness, and are commonly isolated and studied in the laboratory through metallog......
An Overview of Interference Theory of Interference Microscopy
Interference Microscopy Theory Outline
Interference microscopy is an imaging technique that uses light interference to obtain a high-spatial-resolution 3D image of a sample. This type of microscopy provides a high resolution view of microscopic objects, but unlike traditional microscopes, it doe......
Laws of Lens Imaging in Iron and Steel Metallographic Experimental Technology
Introduction
The principle of lens imaging in steel metallographic testing technology is for accurately analyzing the microstructure and performance of materials. In order to measure the size and shape of a small object (metallographic specimen) accurately and quickly, the magnifying power of opt......
