Hardness and deformation properties of solids at very high ...

This paper describes an experimental study of the deformation and strength properties of refractory solids at temperatures up to 2000 °C. It is difficult to make direct stress-strain measurements at elevated temperatures on small specimens of these materials, and consequently the strength property measured was in dentation hardness.

The hardness of solids - IOPscience

Nov 20, 2002 · With brittle solids the high hydrostatic pressures around the deformed region are often sufficient to inhibit brittle fracture. Under these conditions both indentation and scratch hardness are essentially a measure of the plastic rather than the brittle properties of the solid. This provides a simple physical basis for the Mohs scratch hardness ...

Hardness - Wikipedia

In solid mechanics, solids generally have three responses to force, depending on the amount of force and the type of material: • They exhibit elasticity—the ability to temporarily change shape, but return to the original shape when the pressure is removed. "Hardness" in the elastic range—a small temporary change in shape for a given force—is known as stiffness in the case of a given object, or a high elastic modulusin the case of a materi

Properties of Solids. As you should remember from the kinetic molecular theory, the molecules in solids are not moving in the same manner as those in liquids or gases. Solid molecules simply vibrate and rotate in place rather than move about. Solids are generally held together by ionic or strong covalent bonding, and the attractive forces ...
