Why Buehler & Instron Improved the Vickers Hardness Testers

Congratulations to Rudolf Mayer and Steve McMahon ITW, the parent company of Buehler recently recognized two outstanding engineers Rudolf Mayer, Buehler and Steve McMahon, Instron for their contributions to the design of the VH3100 /3300 micro-hardness products. A Vickers hardness tester presses a pyramidal diamond indenter into the surface of the test specimen. The resulting …

DiaMet Hardness Software – Weld Testing Using Vickers Hardness Scale

Weld Image

Welded joints are nowadays indispensable in the automotive and aviation industry. Welds usually combine metallic components to form a structure that is then assembled in production and assembly with other subassemblies. The welds must be able to withstand extreme loads as they are the weak points of the construction. Weld seam inspection is thus a …

Un tronçonnage qualitatif… Est critique pour l’essai de dureté

Cutting Edge Hardness Testing

Dans l’industrie extrêmement concurrentielle des disques de tronçonnage, il est essentiel que le disque soit suffisamment dur pour conserver un bord, tandis qu’une dureté excessive risque de provoquer une rupture fragile. Lors du prépolissage de matériaux durcis, la chaleur résiduelle risque de modifier la microstructure et use prématurément la meule. Les essais de dureté sur …
