(PDF) Effect of heat treatment on microstructure behavior

EN 8 steel is an important grade of steel, used for manufacture of axles and shafts, bolts, gears, studs etc. Heat treatment is an important step in achieving desired mechanical properties and Chemical, electrochemical, thermodynamic and adsorption Jul 17, 2021 · This paper presents the corrosion and inhibition behavior of heat-treated EN8 dual-phase steel with ferrite-martensite structure with pectin in 0.5 M sulphuric acid. The corrosion studies were performed using the weight loss method, electrochemical techniques such as potentiodynamic polarization measurements, and impedance spectroscopy.

Effect of Heat Treatment on Microstructure and

Furthermore, age-hardening heat treatment revealed the presence of scales more widely distributed on the metal surface and highly dispersed ferrite. 3.2 Effect of heat treatment type on the microhardness of SAE 1025 Carbon steel The results of Brinell microhardness test in quadruplicates for each heat treatment is presented in Fig.2. Effect of heat treatment on hardness and toughness of EN8 Jan 01, 2021 · So we perform this heat treatment process in various quenching medium to test the EN8 steels. Few specimen of EN8 steel were studied and analyzed after heating them in the Muffle Furnace between 750 °C and 950 °C followed by quenching in different medium. Oil, Water, and Air are used as different quenching medium. Estimation of Hardness During Heat Treatment of EN8 and Apr 24, 2019 · The hardness of EN8 and C25 steels during Jominy-type end-quench test was numerically estimated. The cooling curve near the quenched end of the specimen was used to estimate the heat flux during quenching. Heat transfer in the specimen during quenching was modeled as a 2D axisymmetric heat conduction coupled with austenite decomposition.

The spectrometric analysis of EN8 steel used in this study is shown in Table1. EN8 is generally used for parts such as general-purpose axles and shafts, gears, bolts and studs. EN8 steel in its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties. Interpretation of the Microstructure of SteelsIt is sometimes the case that a pearlitic steel is too strong for the purposes of machining or other processing. It can then be heat-treated at a temperature below that at which austenite forms, to allow the cementite to spheroidise. The "lamellae" of cementite turn into approximately spherical particles of cementite in an effort to minimise Vol. 4, Special Issue 6, May 2015 Analysis and It is an unalloyed medium carbon steel. EN8 is a medium strength steel, good tensile strength, its suitable for automobile components likes shaft, stressed pin, studs, keys etc. EN8 is a very popular grade of through hardening medium carbon steel, which is readily machinable in any condition.


Jun 12, 2018 · The EN8 grade steel is chosen for heat treatment to study and analysis on the variation in properties and microstructure of EN-8 when different heat treatments are done on it. Also the comparison of microstructural differences . The objective of this study is to analyze the hardness of EN8 steel when different heat treatment
