Due to ever increasing quantities of waste substances and industrial by products, strong waste management is the high concern in the world. This experimental investigation was performed to consider the energy and sturdiness homes of M20 grades of concrete mixes, in which natural sand was once partial changed with waste foundry sand WFS . Natural sand used to be changed with five percentage 0 , 5 , 10 , 15 and 20 of WFS with the aid of weight. A complete of ten concrete mix proportions M 1, M 2, M three and M 4 for M20 grade of concrete with and except WFS have been developed. Compression test, splitting tensile power test and modulus of elasticity have been carried out to evaluate the energy homes of concrete at the age of 7 and 28 days. S. Gopinath | M.

ABSTRACT:- Burnishing, a cold working process, is a very simple and effective method of improving surface properties, which can easily be carried out using existing machines, such as lathe. With changing trends in manufacturing industry, special attention is given on surface finish along with dimensional accuracy and tight geometrical tolerances. Burnishing comes in mind as one of popular finishing process because it is completely chip-less as compared to other finishing processes such as grinding, honing etc. The purpose of the research was to demonstrate burnishing process on ferrous metals namely mild steel alloy. Parametric analysis was done using speed and feed rate as input parameters and surface roughness & surface micro hardness as response variables. Burnishing was performed using Hindustan machine tools (HMT) power lathe (NH 26 model)

Starting From a sample of pure and pre-deformed niobium by cold rolling a severe plastic deformation process was performed using ECAP (equal channel angular pressing) in order to verify the evolution and distibution of the deformation structures and of hardness in the lamination plane of the material. To make the analysis were used: the Scanning Electron Microscope-SEM, optical microscope and a hardness map to have a better view of how homogeneous or heterogeneous a process is in relation to the other. After comparison it was seen that the process through ecap uniformized the microstructure and hardness of the material.

Boring operations are challenging owing to limited process performance due to inherent tool overhang and resulting vibrations. The tool vibrations can be suppressed with insertion of suitable damping methodology. The present work adopts a method suitable for machine operators, where in insertion of packing sheets at the boring tool support has been suggested. Insertion of number of layers causes frictional phenomenon to dissipate the exciting energy thereby damping the vibrations. Substantial improvement of surface quality of the internally machined surfaces has been noticed in the experiments

The paper presents tribological behaviour of hybrid aluminium composite A356/10SiC/3Gr in dry-sliding conditions. Hybrid composites were made with a modified compocasting procedure and tribological tests were conducted on a tribometer with a block-on-disc contact geometry. An analysis of the effects of three sliding speeds ((0.25, 0.5 and 1) m/s) and two normal loads (10 N and 20 N) on the wear volume and wear rate was conducted for different sliding distances. The total sliding distance was 300 m. SEM and an EDS analysis of the wear surfaces of the tested material were also performed. The analysis of the wear surfaces shows an intensive adhesive wear of hybrid composites. Also, the appearance of mechanically mixed layers (MMLs) was confirmed, i.e., an increase in the concentration of iron in the hybrid composite material. Keywords: hybrid composites, wear, aluminium, SiC, graphite, testing

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a decade. Recently, friction stir processing (FSP) was developed for microstructural modification of metallic materials. In this study, SiC particles and Methanol paste were incorporated by using Friction Stir Processing (FSP) into the 6351 aluminum alloy to form particulate composite materials. Samples were subjected to traverse speeds of the FSP tool with and without Paste (SiC+ Methanol). Microstructural observations were carried out by employing optical microscopy of the modified surfaces. For the 100% overlapping, No. of passes caused grain modification in the processed zone.

Microstructure and tribological properties of Al-TiB2 nano surface composite fabricated by Friction Stir Processing (FSP) were evaluated. To vary the percentage of TiB2 three different slot thickness viz. 1mm, 1.5 mm and 2mm were considered. Microstructural evaluations showed a nearly uniform distribution of TiB2 in the aluminium matrix after FSP with the addition of composite powder. Microhardness test results shoes FSW of Al6061-T6 alloy with 2mm groove width has more hardness. tribological properties were evaluated at two different sliding velocities 0.314m/s and 0.48m/s and results shows that at lower loads there is no much difference in wear rate of surface composite made with different slot sizes but with increase in load and sliding velocity wear rate was increased , however, larger slot Al6061-TiB2 Surface composites show better wear resistance.

Mechanical surface enhancement (MSE) techniques have been used to modify the surface reliability properties of many materials by generating ultrafine or even nanometer-sized grains in the surface and subsurface region. These fine grained materials created by mechanical surface enhancement techniques usually have higher hardness and frequently exhibit enhanced mechanical properties. Turn-assisted deep cold rolling (TADCR) process is used to improve the surface integrity of AISI 4140 steel which is commonly used in automobile industry.

Bioactive glass-ceramics used as a replacement material for bone tissues because of its bioactivity, compatibility, and abilities to form a crystallized hydroxyapatite (HA) bonding layer which has a similarity in composition and structure to the inorganic component of bones mineral phase. The major objectives of this research is estimating the effects of using MgO as an additive on the property of bioactive glass ceramic in 45SiO2, 24.5 Na2O, 6 P2O5, (24.5-x)CaO, X MgO where X= 0,1,3 and 5 wt.%. Bioactive glass ceramic was made by traditional glasses melting techniques at 1200°C for 2hr. Compressed sample sintered at (850)°C, the X-ray diffraction test confirmed the formations of (Na2CaSi3O8) and (Na2Ca2Si3O9) phases in the structure of pure bioglass-ceramic and with (1wt.%) MgO, while (Na2CaSiO4) and CaMg(SiO3)2 phases were present in the structure of bioglass-ceramic with (3wt.%)MgO, and CaMg(SiO3)2 phase in the structure of bioglass-ceramic with (5wt.%) MgO. Results of mechanical and physical studies showed that increasing (MgO wt.%) in glass structure led to improving the bending strength, compressive strength, microhardness, and density associating with decreasing in porosity. FTIR confirmed the formations of the Si-O-Mg bond. The biological test was done by immersion the sample in (SBF) simulated body fluid for (21 days). XRD, SEM and pH tests revealed that appetite layers made on the samples surface, giving an evidence of their bioactivity. As general the results of the present study demonstrate that partial replacements of CaO by MgO in 45S5 glass ceramic improve the mechanical properties without altering the bioactivity suggesting that glass ceramic was suitable for the biomedical applications
