Abstract
On the basis of an analysis of indenter penetration diagrams some mech anical properties of surface layers of bulk A(II)B(VI) compounds were investigated. These crystals were grown from the melt, and vapour phas e. Values of Young's modulus, activation volume of microindentation, p arameter of hysteresis loss were determined. The analysis of the resid ual deformation during microindentation permitted to evaluate the degr ee of covalent bond ''stiffness''. An original combination of the mech anical properties of the investigated crystals typical for metals, pol ymeric materials and glasses was discovered.
