Heat treatment is an essential technique for influencing workpiece characteristics. Several industries focus on reliable part design to avoid breaking parts, e.g. by decreasing material weight and ...

While hardness testing does not provide a direct assessment of product or raw material performance qualities, hardness correlates directly to qualities like strength and wear resistance. Hardness ...

This class presents a description of each hardness testing method, along with discussions on how to choose and perform a test, how to read hardness ratings, and how to prevent common errors. Hardness ...

Researchers wanted to see which CAD/CAM composites for molars were hardest and held up best after toothbrush abrasion testing. After putting six composites through rigorous testing, they discovered ...
