In materials science, the hardness of a material measures its resistance to deformation by indentation, scratching or other physical actions. By this metric, plastics and soft tissues are said to be ...

A team of scientists has developed a substance so tough that it can go toe to toe with diamonds, which are considered the hardest naturally occurring substance on Earth — a discovery they say could ...

Geologists do it according to the Mohs Scale of Hardness. There. That’s your “hardness” joke for the post. Now down to business, with the hardest (and softest) scale there is. In 1812, people had just ...

It’s only a matter of time before a movie villain pulling off the crime of the century needs a cutting tool that is harder than anything else on Earth. Perhaps it’s a burglary that involves cutting ...

hardness scale. For this case, which uses the diamond indenter and a 150 Kg total load, the Rockwell hardness is a C-scale number.

Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...
