Live Experience: State-of-the-Art Sample Preparation and Hardness Testing

Open House Week at Buehler ITW Test & Measurement: Leinfelden-Echterdingen, Germany, April 2022 – From May 2 to May 6, 2022, Buehler ITW Test & Measurement GmbH invites to the opening of the laboratory at its new European location in Leinfelden Echterdingen. Conveniently located next to Stuttgart Airport and Stuttgart Trade Fair Centre, the company […]

Metallographic Specimen Preparation and Testing

Preparation of magnesium and its alloys is rather difficult due to the low matrix hardness and the higher hardness of precipitate phases that lead to relief problems, and from the reactivity of the metal. Mechanical twinning may result during cutting, grinding, or handling if pressures are excessive. Final polishing and cleaning operations should avoid or […]

Image Analysis for Hardness Testing

Hardness testing is a fundamental characteristic in analyzing component properties, and, as an important materials testing tool, this critical parameter can performed and measured by a multitude of methods and techniques. While some hardness test types such the Rockwell test will yield fast, single process results based on indentation depth, many of the commonly used […]

Advanced Techniques for Hardness Testing

Materials testing, including hardness testing, is a fundamental but useful element in analyzing component properties, and can be accomplished by a multitude of methods and techniques. Determining the hardness value can provide valuable insight to the performance, durability, strength, flexibility, and capabilities of a variety of material types from raw materials to prepared specimens and […]

Gage Repeatability and Reproducibility

What is Gage Repeatability & Reproducibility (GR&R)? Gage Repeatability & Reproducibility, commonly known as a GR&R, is a statistical method used in process control (SPC) to measure the precision and variation present in a measuring device and the subsequent effectiveness of the instrument to be used as a measuring tool. There are, as the name […]

Non-Destructive Hardness Testing

Nondestructive testing (NDT) or Nondestructive evaluation (NDE) is a method of materials testing to assess the characteristics of a component without altering or destroying it. NDT is important in the materials testing industry where quick, dependable information on finished or raw material is needed. This may occur during the production stage, during the service life […]
