Material Thickness When Choosing a Rockwell Scale

Hardness Scales

Are you concerned about which Rockwell scale to use for thin materials? Of primary importance in Rockwell scale selection is material thickness. Since the 30 Rockwell scales are distinguished by total test force as well as the indenter type, a load or force that is excessive for a given material thickness will ultimately be influenced …

Preparation of Difficult Materials for EBSD Electronic Backscatter Diffraction

Ti Standard Map All Euler Coloring

Metallographic preparation of soft and very ductile materials can be challenging, especially when the analysis techniques used require perfection, such as examination using Electron Backscatter Diffraction (EBSD). Following these guidelines will help to ensure that your preparation is both efficient and effective: Most problems experienced by users start with poor sectioning. Section the sample as …

Selection of Compression Mounting Compounds

3 Color Sample

Selection of the correct mounting compound can make all the difference in achieving high quality preparation. Edge retention compounds such as EpoMet have excellent hardness and shrinkage properties, and are best for hard materials where edge inspection is required as well as for resistance to strong chemical etches. Phenocure is the lowest cost option, and …

Hardness Conversions

Hardness Conversion

Need to produce Brinell hardness values with your Rockwell tester? Hardness conversion makes it possible. Depending on application and availability, different hardness test equipment is used, each presenting their results in a different hardness-scale (e.g., Vickers, Rockwell or Brinell). Too often there is a need to present the hardness results in a different scale than …
