Indentation hardness depends on the time of loading and on the temperature and the inforination so obtained inay be correlated with the creep properties of the solid. At very high rates of loading as in dynamic measurements it is possible to calculate the dynamic
Hardness and deformation properties of solids at very high
With sintered porous specimens the fall in hardness is augmented by collapse of the structure and compaction of the material. At higher temperatures the behaviour is dominated by the intrinsic properties of the solid and the hardness properties of the sintered material resemble those of fully compacted crystalline specimens.

The features which help us to recognise a particular material are called properties of the material. 1. Hardness and softness: Some materials are hard and some are soft. Stone is hard while clay and stone are soft. Some materials keep their shape unchanged when pressed and some do not. Most solids have their shape unchanged when pressed while liquids and gases do not. 2. Transparency: There

Hardness . Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied (Fig. 8.41).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness: scratch hardness, indentation hardness, and rebound

Properties of solids. As described in the previous section, crystalline solids can vary in their atomic compositions, bonding, and structure. Together, these attributes determine how the different solids behave under different conditions. Solids have many different properties, including conductivity, malleability, density, hardness, and optical transmission, to name a few. We will discuss just

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 between the atoms, ions, or molecules in solids are
