Several commonly used alloy steel microstructure of alloy steel with different alloy content, can be divided into three types: less than 5% of the total amount of alloying elements called low-alloy steel; alloy elements ranged from 5 to 10% is called in alloy steel; alloy element is greater than 10% is called the high alloy steel.
The microstructure of test sample including inspection and erosion erosion before and after etching. Before inclusion, main test sample in the black stone, cracks, pores and defects caused by grinding process. The microstructure of the main test sample after etching.
The microstructure of (microstructure) is to use appropriate methods (such as erosion) metal grinding surface of the specimens or the complex type or with appropriate method made film on microstructure optical microscope or electron microscope was used to observe the tissue.
Test sample for metallographic microscope as desktop, vertical, bedroom. Microscope should be installed in a dry ventilated, no dust, no vibration, no corrosion of the indoor atmosphere, and placed on the desktop and solid base, with the best vibration absorption mechanism
