VERIFICATION OF CREEP ANALYSES OF A - Energiforsk

Our services are used for the inspection of a variety of materials such as density, temperature, hardness, etc. Founded in the year 1986, we aim to offer quality-assured assessment for our valued customers. Metallographic testing is primarily a collection of visual and imaging techniques. Consequently, samples must be prepared and preserved with the utmost care to ensure accuracy in their appearance.

The steps that needs to be followed for sample preparation are documentation, sectioning, cutting, mounting, planar grinding, rough polishing, final polishing, etching, microscopic analysis and hardness testing. Of the metallographic procedures listed, the macroetch test is probably the most informative, and it is widely used for quality control, failure analysis, and research studies.
