Experimental and Finite Element Simulation of Nano-indentation on Metal Matrix Composites: Hardness Prediction
The scientific importance of nanocomposites are being increased due to their improvedproperties. This paper is divided into two parts. First, Al-Al2O3 nanocomposite wasproduced by using ball milling technique followed by cold compaction and sintering.Microstructure and morphology studies were done through SEM, TEM, and EDX anal-ysis on the produced powder. The mechanical properties of the produ...
متن کاملTemperature Effect on Mechanical Properties of Top Neck Mollusk Shells Nano-Composite by Molecular Dynamics Simulations and Nano-Indentation Experiments
Discovering the mechanical properties of biological composite structures at the Nano-scale is much interesting today. Top Neck mollusk shells are amongst biomaterials Nano-Composite that their layered structures are composed of organic and inorganic materials. Since the Nano indentation process is known as an efficient method to determine mechanical properties like elastic modulus and hardness ...
متن کاملFinite element analysis of elastic-plastic solids under Vickers indentation: surface deformation
Finite element modeling has been used to study the development of surface deformation during indentation with a Vickers indenter. A wide range of materials with different elastic modulus and yield stresses are examined. Results show that in a pyramidal indentation process, for a perfectly plastic material, sinking-in during loading can change to pile-up in unloading. This phenomenon depends on ...
متن کاملThe Effect of Aging on Nano-Hardness and Modulus of Elasticity of Four Types of Composites: An in-vitro Study
Introduction: Resin composites are an important part of restorative treatment in modern dentistry. There are many trademarks available in Iran market and physico-chemical properties of many of these resin composites are not evaluated yet. This study was carried out to evaluate the physico-chemical properties of four available resin composites and also to assess the effect of aging on their prop...
متن کاملMechanical Properties and Microstructural Evolution of Ta/TaNx Double Layer Thin Films Deposited by Magnetron Sputtering
Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...
