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 ...

HARDNESS, as recent correspondence in NATURE (vol. cvi., pp. 377, 440, 534, 599, 662, November, 192o–January, 1921) has shown, is a subject of interest to both the engineer and the physicist. Whatever ...

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 ...
