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 …

CHD testing with DiaMet

Focus on the task – improve efficiency Hardness testing is commonly used in the field of process control of heat treatment and to evaluate surface hardness and case-hardened depths of surface engineered materials. Hardness case evaluations can be highly automated, which can represent enormous savings in terms of time and efficiency. These systems can incorporate …

Out-of-Box Concept with Mount Fixturing, EZ Clamp

EZ-Clamp

Holding a metallographic sample both steady and level during hardness testing is essential to ensure accurate and repeatable results. To make this mount both convenient to use, versatile and effective can be a challenge. An innovative fixturing method was developed by Buehler’s Wilson Hardness Testing Group over 10 years ago. This fixture is not widely …

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 …
