Aim of this research paper is to investigate the effect of heat treatment on mechanical propertiesof Mild Steel (ASTM A36). Heat treatment was carried out in a furnace at a temperature of 800oC, after heating at such temperature quenching was carried out using brine solution. It was observed that on heating the mild steel resembles the properties of cast iron along with increase in boiling temperature.Various mechanical properties such as Tensile strength, yield strength, modulus of elasticity, bulk modulus, shear modulus, Poisson’s ratio, elongation percentage & hardness are analyzed to investigate the effect of heat treatment on the mild steel. To investigate the microstructure of the heat treated surface, grinding with the help of rough emery paper and by using alumina paste on double disk polishing machine was carried out. It was revealed that heat treatment produces significant effect on properties of Mild steel.Keywords

Aim of this research paper is to investigate the effect of heat treatment on microstructural behavior of Cast Iron (ASTM A48). For investigating the effect heat treatment was carried out in stages. In first stage material is heated in a furnace at a temperature of 850°C, followed by quenching inside the furnace. Further in second stage material was heated at a temperature of 900°C, followed by quenching with the help of cooled still air. It was observed that on heating, cast iron resembles the properties of mild steel along with increase in melting temperature. It reduces the cost to be bear for making mild steel.Various mechanical properties such as. Tensile strength, yield strength, modulus of elasticity, bulk modulus, shear modulus, Poisson’s ratio, elongation percentage & hardness are analyzed to investigate the effect of heat treatment on the cast iron. To analyze the microstructure of the heat-treated surface, grinding with the help of rough emery paper & fine emery paper and by using alumina paste on double disk polishing machine was carried out. It was revealed that heat treatment produces significant effect on properties of cast iron.Keywords

In present study an attempt was made to numerically simulate the slurry erosion process using material failure modelof progressive damage slurry erosion process was numerically simulated by using material failure model (MFM) of progressive damage instigation and promulgation for the impingement of solid and liquid particles on the solid surfaces. To simulate this problem Finite element analysis based three dimensional Abaqus Explicit software has been used. The mixture which comprises of solid and liquid particles known as slurry, when impinged upon the surface of the component surface leads to impingement of solid and liquid particles on the solid surface which leads to dreadful conditions on the surface known as slurry erosion. The proposed model uses the FEA concepts of adaptive meshing, strain-dependent damage initiation Criteria, a general contact algorithm, damage propagation, enhanced hourglass section control and multiple particle Impingements to study the slurry erosion process. For the purpose of experimental validation and due to the availability of material properties, surface coatings of a powder on steel are deposited by the HVOF Coating process. The slurry erosion tests are performed on these depositions using the abrasive slurry at different impingement angles. The tests are made in an Impact test erosion rig. From these tests, the material removal rate (MRR) values and depth of penetration including the profiles of the craters are computed as a function of the slurry jet impingement angles. The numerically computed results are compared with the experimental results and are shown to be in good agreement.Keywords

Slurry erosion of turbine components in hydro power plants is a serious problem faced all over the world. Researchers are continuously working on investigating the ways to mitigate the effect of slurry erosion. Different techniques are employed to protect the material from deteoriation of its life, techniques such as filtration of the sand particles were carried out to reduce the amount of sand particles in the water which is impacting on the turbine components and designing the shape of turbine components in such a manner so as to mitigate the effect of slurry erosion. Still slurry erosion is most priortize area among the researchers as it is causing heavy economic losses. As a new alternative, researchers are exploring the thermal spray coating technique as an option by which the surface properties of the material will be improved. Thermal spraying is one of the most prominent methods used now a days to prevent the material from abrasive wear, high temperature corrosion, erosive wear and stresses, as it increases the life span of material used in service. High velocity Oxy Fuel (HVOF) spraying is among the thermal spraying techniques which are known for its various characteristics such as providing hardness, wear resistant and dense micro structured coatings. In this paper an attempt has been made to present a state of art review of the work done by various researchers to prevent slurry erosion of hydraulic machine components by using HVOF Spray technique.Keywords
