Magnesium 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

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

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

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)

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.
