What is Cryptocrystalline Martensite? Cryptocrystalline martensite is a microstructural morphology of martensite. Its main feature is that, when observed under a metallographic microscope, there are no obvious needle-like or bamboo-leaf shapes, but rather a blurry, darker-colored area that seems to ...

Selection of Control Method for Simulated Climate Chamber There are two types of temperature and humidity environmental test chambers: constant test chambers and alternating test chambers. Generally speaking, high and low temperature environmental test chambers refers to constant temperature, and ... Read More

What is deformation in metal materials? When metal materials are subjected to external forces and their shape and size change, this is called deformation. Material deformation includes plastic deformation and elastic deformation. For materials that deform, if the deformation disappears when the ... Read More

Select Humidity Range of Climate Chamber The humidity index given by the temperature and humidity environment test chamber is mostly 20%~98% or 30%~98%. If the temperature and humidity environment test chamber does not have a dehumidification system, then the test chamber with a humidity range of 60... Read More

What is Controlled Rolling and Controlled Cooling? Within the industry, there are two ways to interpret controlled rolling and controlled cooling. The first is the split approach, which separates the process into controlled rolling (CR) and controlled cooling (AC/ACC, controlled cooling/accelerate ... Read More

Select Temperature Range of Climate Chamber At present, the temperature range of environment test chambers is generally -40℃~150℃. Some test equipment can reach a low temperature of -70℃ and a high temperature of 180℃. For -40℃~150℃, unless there is a special need, such as the installation location ... Read More

Principle of Vision Measuring Machine The vision measuring instrument is a device that uses optical imaging and image processing technology for measurement. Its principle is based on camera imaging and image feature extraction. The principle of the image measuring instrument is introduced below: ... Read More

Common Metal Mechanical Properties The mechanical properties of metal materials refer to how metals behave when subjected to external loads or the combined effects of loads and environmental factors like temperature, medium, and loading rate. Mechanical Properties of Metals Common Indicators of ... Read More

Calibration of Microhardness Tester Most microhardness testers lead a charmed life in comparison to Rockwell and Brinell testers. They usually wind up in laboratory environments, free from the dirt and oil that can plague other hardness testers. Consequently, microhardness testers tend to have long ... Read More

Humidity Range of Temperature and Humidity Test Chamber 1. Humidity range of constant temperature and humidity test chamber We know that the humidity of constant temperature and humidity test chamber is relative, such as 50%RH at 30℃; 85%RH at 85℃, and so on, rather than from the lower limit of high ...
