Metallographic etching reveals concealed microstructures in metals that recount the entire tale of material performance and properties. This essential technique is utilized daily in materials laboratories. The procedure brings to light grain boundaries, phases, and inclusions that would otherwise remain invisible. Even the most sophisticated microscopy cannot discern important microstructural details without etching. Such details […]
Metallography is a science and an art that examines the microstructure of metal and metal alloys. The history of metallography dates back to approximately 7000 BC when humans discovered that there existed a method of shaping metal through the use of fire. The early specialized discipline has evolved into an important discipline that reveals and […]
The Vickers hardness test was created in 1921 by George E. Sandland and Robert L. Smith of Vickers Ltd. One of the most versatile hardness testing techniques available today is this test. With one of the most comprehensive hardness testing scales available, it was developed as a substitute for the Brinell method and is currently […]
