Microhardness studies of SnI2 and SnI4 single crystals

Abstract

The variation in the microhardness of tin-di-iodide (SnI2) and tin-tetra-iodide (SnI4) crystals has been determined using Vicker's microhardness indentor. It is observed that the microhardness of the crystals depends on the applied load and is independent of the duratidn of loading. Viekers Hardness Numerals (VHN) for SnI 2 is found to be greater than that of SnI 4 crystals. Mayer's equation and implications have been discussed.

Microhardness studies of GaTe whiskers

“…A plot of the square of the length of diagonal, d 2 (mm 2 ) against load p (g) gave a straight line passing through the origin as shown in the fig 3, indicating that the error in loading is nil in the studied range of loading [21].…”

“…It can be used as a suitable measure of the plastic properties and strength of a material [46]. Stillwel [47] defined hardness as resistance against lattice destruction, whereas Ashby [48] defined it as an ability of a crystal to resist a structural breakdown under an applied stress.…”
