Ni-based super alloys are metallic materials with exceptional combinations of creep and oxidation resistance at high temperatures. Wrought alloys are hot formed at high temperatures and subsequently annealed and aged. The final mechanical properties of the alloys are a combination of the grain size generated during the process and the precipitation state after aging. In fact, precipitation phenomena are complex for these alloys, which contain up to 12 different elements in their compositions. This study deals with the forming characteristics of Haynes 242. Hot forming is easy to carry out as it requires less efforts but it makes material more dynamic in nature. Haynes 242 was deformed at different temperatures and strain rates. The variation of these parameters on the stress strain flow curves were analysed and study has made on the microstructure evolution and recrystallised grain size.

The objective of the present study is to prepare hybrid composites of Aluminum2618 reinforced with E-Glass fibres and Silicon carbide (SiC) by stir casting technique and to evaluate the effect of Severe Plastic Deformation (SPD) on the Characteristics of Al2618-E-Glass-SiC hybrid composites. Specimens were prepared by adding weight percentage of reinforcements in 2% increments (4% SiC with 2% E-glass fibres and 6% SiC with 4% E-glass fibres). Silicon carbide particles of 35 μm size were added to the matrix. The SPD through Equal Channel Angular Pressing (ECAP) was carried out at room temperature. The specimens were subjected to single pass using an ECAP die of 90o channel angle. The performance of the specimens was compared with as casted composites. The micro structural study revealed that the specimens are defects free and also the particles are distributed uniformly. Hardness of the hybrid composite has improved before and after SPD process. The study reveals a reduction in the grain size due to strain hardening by the ECAP process which signifies the enhancement in the mechanical properties of hybrid composite materials.

Elsevier Ltd, VIT, Vellore, TN. , pp. 13282-13289, 2018.[Abstract]


Composite materials have many advantages over monolithic materials and are being used in modern Engineering Technologies in various applications. In this study an attempt has been made to study the characteristics of composites made of Al6061 with Hematite (Fe2O3) as reinforcement. Aluminum metal Matrix Composites (AMCs) are prepared by varying the percentage of reinforcement as 1%, 2%, 3% & 4%.The specimens were fabricated by stir casting technique which ensures uniform mixing of the reinforcement with matrix material. The Grain size has significant influence on ductility. The Severe Plastic Deformation (SPD) imposes larger plastic deformation and produces ultra fine grains in the specimen. The specimens were subjected to SPD through Equal Channel Angular Pressing (ECAP). It is observed from the results that the deformation load has increased significantly as the% of reinforcement increased, ensuring higher strain hardening. The microstructure of specimens for different percentage reinforcement was studied under Scanning Electron Microscope (SEM). The study reveals an enhancement in the Mechanical characteristics and reduction in the discontinuities of the grain boundaries of micro structure after ECAP process. © 2017 Elsevier Ltd.

Aluminum Metal Matrix Composites are being used widely since 3 decades in Engineering and non-Engineering applications due to their versatile properties. The properties of the composites can be enhanced by subjecting them to Severe Plastic Deformation (SPD). Equal Channel Angular Pressing (ECAP) is one of the most commonly used methods of SPD, which produces ultra-fine grains in the structure. In this work AMCs have been fabricated using Al6061 alloy as matrix material and Hematite (Fe2O3) as reinforcement. Stir casting technique has been used for the fabrication of composites by varying the composition from 0% to 4% in steps of 1%. The specimens are subjected to two passes of ECAP. The load for the deformation of the specimen has increased as the % reinforcement increased and also from first pass to the second pass. Performance of the composites before and after SPD is studied by evaluating different properties and an enhancement in the properties is observed.

The addition of zinc to aluminum with magnesium or copper produces heat treatable alloys of highest strength which can be used for structural applications. This work is an attempt to investigate any improvement in hardness and fracture toughness by coating aluminum 7075 alloy with zinc. The zinc coated aluminum 7075 alloy was fabricated using Time Dependent Electro- Plating Technique. The varying thickness of zinc coating was obtained based on the time estimates, which includes 10, 15 and 20 μ. Specimens were prepared according to ASTM standards, which were then tested for mechanical properties such as surface hardness, tensile strength and fracture toughness at different loading conditions. A significant improvement in hardness was seen with the coating, but remained constant for further increase in coating thickness. The yield stress of zinc coated aluminum alloy increased (587.11 N/mm2)when compared to uncoated aluminum alloy 7075 - T6 (537.12 N/mm2), with an increase in brittleness. The fracture toughness test on CT specimen under plain strain condition for coated specimen showed an increase in KIC value by 7.25 % compared to that of uncoated aluminum 7075-T6 alloy. Optical microscopy analysis shows that there is a good bonding of zinc coating on aluminum. © (2014) Trans Tech Publications, Switzerland.

This investigation mainly targeted on study of hardness and tensile properties of Al 7075 with different metal coatings like Nickel, Zinc and cadmium. Coating of these metals on Al 7075 is successfully achieved by time dependent electroplating method for different thicknesses of 10, 15 and 20 Microns. These metal coated Al-7075 specimens were tested for hardness and tensile properties according to the ASTM standards. It's found that Nickel coated alloy shows excellent hardness and tensile properties compared to Zinc and Cadmium coated alloys. 20 μm Nickel coated alloy exhibits highest hardness number of 102 HRB and Maximum Tensile Strength of 603 MPa than Zinc and Cadmium coated alloy. The microstructural studies authenticated that the coating of Nickel, zinc and cadmium on Al 7075 is homogeneous.

Metal Matrix Composites (MMCs) are used in aerospace, transport, automotive, marine engineering due to their light weight with improved strength, stiffness and wear resistance. Wear is one of the reasons for the failure of the machine components. It is difficult to accurately predict the life of components due to wear, because, generally the wear rates are largely scattered. An attempt is made to study the Wear characteristics of Hematite (Fe2O3) reinforced Aluminum 6061 Metal Matrix Composites. The reinforcement is added in particulate form of 40-45 μm with an increment of 2% from 0% to 8% (by weight). Composites are fabricated by liquid metallurgy technique. The Microstructural study on as cast Al6061-Fe2O3 compositesreveals uniform distribution of reinforcement particles. The wear test was conducted on the specimens by varying speed from 200 - 400 rpm & load from 50 - 100 N. The wear rate was measured by the weight loss of the specimen. The results show that there is an increase in the wear resistance with increase in percentage of reinforcement. The wear factor has decreased 30 - 40% at 8% of reinforcement as compared to base matrix material. © 2017 Elsevier Ltd. All rights reserved.
