Requirements of Test Specimen for Vickers Test 1, The Vickers hardness test is adaptable to a wide variety of test specimens ranging from large bars and rolled sections to minute pieces in metallographic mounts. In general, the backs of the specimens shall be so finished or the specimens shall be so ... Read More

Principles of Centrifugation At its core, centrifugation is separation through sedimentation. The denser particles sink to the bottom of the container, while the more lightweight particles remain suspended. Centrifugation will displace particles that are even slightly different in density, and is ... Read More

Why Need Sample Mounting? Small-sized samples are often encountered during metallographic observation, so the samples are often mounted for easy grinding and polishing. To sum up, the applications of mounting mainly include the following aspects: Protect the Operator: It is convenient to hold thin, ... Read More

What are the factors that affect the fatigue strength of materials? Fatigue fracture often starts from the weakest place. If there are defects inside the material, such as cracks, brittle inclusions, etc., fatigue may start from these internal weak places. If the internal structure and performance ... Read More

What Is Dew Point? In simple terms, the dew point is the temperature at which the air can no longer hold all of its water vapor so that some of that vapor condenses into liquid water, forming dew or frost. More technically, it is a meteorological term that refers to the temperature to which air must ... Read More

Kinds of Rockwell Hardness Scales Initially, 15 scales were created using a 10 kg preliminary force; 60, 100 or 150 kg total test forces combined with diamond; 1⁄16, 1⁄8, 1⁄4 and 1⁄2-inch diameter ball indenters; and 0.2 millimeter per Rockwell point. These forces are called the Regular Rockwell ... Read More

R, Saturation barrel, manually refill water: tap water or purified water, require clean. S, Machine cover supporting frames:：Support cover use. T, Water inlet: saturated barrels and test chamber heating water from this port automatically supply, require clean water free of impurities, the water ... Read More

Does The Environment Affect Microhardness Testing Because of the light loads utilized in microhardness testing, vibration can contribute to loading accuracy. Even if the part is not impacted during loading, the oscillation of the indenter or the test specimen can cause the indenter to work its way ... Read More
