An Overview of Ceramic Matrix Composite
Abstract: Ceramic materials often exhibit a combination of useful physical and mechanical properties, including high refractoriness, but their applications are restricted due to their brittle behaviour; in an attempt to improve the strength, and particularly the toughness, of brittle ceramics particle-strengthening and fibre-reinforcement have been utilized, with limited success. The factors which affect the mechanical properties of these composite systems are discussed, and the various experimental systems that have been investigated …

Fabrication and characterization of Aluminum-Granite-Graphite Metal Matrix Composite
Abstract: Moving machine elements are constantly subjected to wear and tear. Machine life can be improved by using hard and wear resistant materials. Most of machine elements are made of metals or alloys. These materials alone cannot meet the requirements of design of long-life machines. Naturally occurring hard materials lack the strength to withstand the machine loads. Composite materials provide the solution to such requirements. Based on requirement, a composite material …

Characterization of the Impact Strength in Cryogenic Treatment of TIG Welded Nickel-based Superalloy
Abstract: The TIG welding of the IN617 heat and oxidation resistant has been precisely controlled through welding parameters, while γ'-Ni3(Al, Ti) phases predominantly controlled solution strengthening, and precipitation strengthening and carbides in γ matrix, as well as γ' precipitate’s shearing mechanism is prominent to enhance strength of superalloys. The high hardness has been preserved owing to strengthening major elements such as Cr, Co, and Mo etc., and the well coherency maintain …

A Critical Evaluation of Polypropylene Impact Copolymer Morphology
Abstract: In order to improve Polypropylene (PP) impact strength, the process of copolymerizing propylene with ethylene is being used. Polypropylene copolymer is essentially a rubber-toughened material consisting of polypropylene homo-polymer matrix in which ethylene-propylene rubber (EPR) is distributed. The overall impact behavior of the copolymer is solely controlled by the rubber morphology and its distribution in polypropylene matrix, which plays a critical role on crystallinity. Even a similar impact grade polypropylene …

Review on the Mechanics of Lightweight 3-D Graphene Assembly
Abstract: The purpose of this paper is to improve the results of Recent advances in three-dimensional (3D) graphene assembly, it has shown how we can make solid porous materials which is lighter than air. In its two-dimensional form, graphene is thought to be the strongest of all known materials. But researchers until now have had a tough time decoding that two-dimensional strength into beneficial three-dimensional materials. It is possible that these …

To Analyze and Study CNC Lathe in Turning Machining Parameters
Abstract: Metal matrix composites (MMCs) consists an important class of design which have weight-efficient structural materials that are inspiring every field of engineering applications. There has been an increasing interest in composites containing low density and low-cost reinforcements. Among various discontinuously dispersed solids used, alumina is one of the most inexpensive and low-density reinforcement available in large quantities as solid waste by-product during combustion of coal in thermal power plants. Hence, …

Hardened Steel an Appliance with Low Degeneration
Abstract: Combination of high hardness, toughness, and strain hardening capacities with reasonable ductility have privileged Hadfield steel in sectors such as mining, transportation, military, agricultural and earthmoving equipment. Micro- porosities formation during casting by last solidifying liquids at inter-dendritic spaces in directional solidification have been insidious crack initiators during service exposure. Particulate penetration resistant wear part surfaces for secondary and tertiary crushers are found to add chromium and vanadium prone to …
