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 ...

Sample Preparation Before Micro Vickers Hardness Testing In most cases, samples are sectioned and mounted prior to micro Vickers hardness testing. The samples are then ground, sanded and polished to provide a test surface free of scratches and surface texture. Sometimes production demands do not ... Read More

Common Problems in Microhardness Testing Microhardness testers are delicate instruments. Extremely light forces (typically from 10 to 1,000 g.) must be accurately applied, and the resultant impressions (some as small as 10 microns) must be precisely measured under high magnification. And so there ... Read More
