Solar Atmospheres Inc. of Souderton, Pa., received MedAccred critical process reaccreditation.

The Doctor was recently called in to investigate a variable-hardness issue involving rotary cutting dies.

AMH55 allows users to maximize their productivity and easily measure impressions on various surface conditions with accurate micro-/macro-indentation hardness testing available in fully automatic, semi-automatic and lite configurations.

Shimadzu’s HMV-G microhardness testers combine ease-of-use with reliable operation and include models ranging from stand-alone testers, with manual reading using an optical microscope, to fully automated testers that increase efficiency by testing intricate patterns without supervision.

Unlike the Wright Brothers, Hugh Rockwell and Stanley Rockwell were two engineers working for the same company who shared nothing more than a common last name and an interest in developing a better type of hardness test, specifically to test the hardness of bearing races.

A scenario and question has been provided by one of our readers as a subject that dovetails into our series of blogs on Hardness Testing (Parts 1-12). We set up the scenario in part 1 and address the Q&A in this part.

The following scenario and question has been provided by one of our readers as a subject that dovetails into our recently completed 12-part series on Hardness Testing.

Microindentation hardness testing is a very powerful tool for characterizing materials and diagnosing problems. It is a complicated process, however, and the subject is rarely taught in schools.
