“…The micro hardness of -glycine crystals were determined using Vickers hardness tester at room temperature. For each load (P), an average of at least three impressions were recorded and the average of diagonal length (d), of the indentation mark after unloading were measured using a calibrated micrometer attached to the eyepiece of the microscope [11]. The work hardening coefficient (n) is measure of the strength of the crystal.…”

Single Crystal of γ-glycine lithium nitrate with non-linear optical material have been grown by slow evaporation method at room temperature. Structural and Crystalline nature of the grown γ-glycine lithium nitrate crystal was confirmed by powder X-ray diffraction technique. UV-Visible transmittance study was performed to analyze optical transparency of γ-glycine crystal and found that the crystal was transparent in the entire visible region. The mechanical properties of the grown crystal was subjected to Vickers hardness test and the Brittleness index (Bi), Fracture toughness (Kc), Elastic stiffness constant (C11) were estimated.

“…This hardness is an intrinsic hardness of a crystal. The hardness properties are associated with the structure of a crystal material and hardness studies are carried out to understand plasticity of the crystal [8]. Microhardness studies of various crystals using Vicker's indentor have been reported by many researchers [9,10].…”

Good quality diglycine perchlorate (DGPCL) single crystals were grown by slow evaporation solution growth method using the combination of glycine and perchloric acid in the ratio of 2:1. Single crystal X-ray diffraction and mechanical characterization of the grown single crystals of diglycine perchlorate were analyzed in this article. Lattice parameters, space group and crytal system were found from single crystal X-ray diffraction analysis. All the cell parameters and space group are in a good agreement with the reported values. Mechanical properties, such as Vicker's microhardness number, work hardening index, standard hardness value, yield strength, fracture toughness, brittleness index and elastic stiffness constant values, were determined using Vicker's microhardness tester.

“…From the hardness number, the yield strength ζ y has been calculated using the relation (for n>2) ζ y= (H v x (0.1) n-2 ) /3.The calculated values of yield strength ζ y for GAS crystal is shown in the Table 2.The elastic stiffness constant (C 11 ) has been calculated for the grown crystals using Wooster's empirical relation C 11 =H v 7/4 [17,18].The obtained values of stiffness constant for different loads are given in the Table 2. It is observed that both the values of yield strength and stiffness constant increase with increase of load in the case of GAS crystal.…”
