    Hardness and deformation properties of solids at very

    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.get price

    The hardness of solids IOPscience

    2002-11-20  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 hardnessget price

    These properties help us to recognise them. We touch a material, see its color, smell it and thereby recognise it. 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 plastic are soft.get price
