This paper presents analysis and comparison into mechanical behaviour and microstructural attributes of postweld heat-treated AISI 1020 (0.21%-C) plates joined by the shielded metal arc welding (SMAW) process. The purpose of this work is to heat the welded samples uniformly so that a possible formation of austenite can be obtained, and hence, residual stresses, if any, can be recovered. Four pairs of such steel were taken and welded to form four joints. Welding was followed by heat treatment. The heating temperature and holding time were selected as 1040°C and 60 minutes, respectively. Different cooling media such as sand, water, oil, and air were used to cool the samples. Hence, there were four different samples according to their physical conditions: sand-cooled, water-quenched, oil-quenched, and air-cooled. For analysing mechanical behaviour of all the plates, standard-shaped specimens were prepared out of them. The tensile strength, impact strength, hardness, and the microstructural attributes were analysed in four welded samples after heat treatment. Significant variations in tensile strength and hardness were reported when compared with each other. Oil-cooled sample showed a remarkable enhancement in tensile strength. The sand-cooled sample possessed the highest toughness, whereas water-quenched samples were found to be highly hard. Furthermore, a good combination of strength, hardness, and ductility was reported in oil-cooled sample. Pearlite (coarse and fine) and martensite were the main microstructural findings in the study. A clear vision of ferrite, cementite, and martensite on various heat-treated samples made this study important. All the mechanical properties are in good corroboration with microstructure. A significant refinement into all the mechanical properties was achieved in this work.

“…The quality characteristics can be measured by smaller-the-better, nominal-the-better and the larger-the-better types. In this study, the larger the better type is taken for energy absorption capacity measurement through various input parameters [5]. For optimal level of input parameter, the SN ratio should be high as higher SN ratio represents better quality characteristic [8].…”

“…The commonly used welding processes are electric arc welding, Tungsten inert gas (TIG) welding, Gas Metal Arc Welding (GMAW), friction welding etc. Among them TIG welding are most suitable particularly in welding of thin sheets as GMAW process have high deposition rate, high welding speed and deep penetration [2][3][4][5]. The well-established process which is used for welding process is TIG.…”

This paper aims to investigate the effect of input parameters on plateau stress and specific energy of thin-wall structure circular mild steel (MS) tube. 32 samples of tube have been fabricated in two sets, one is without weld (WOW) and another is with weld (WW), having same dimensions. The tube was made up of available commercial MS (AISI 1010). During compression test the value of plateau stress and specific energy are obtained at varying input parameters and compared the results between WOW and WW tube samples. And its chemical composition verified with the help of Energy-dispersive X-ray spectroscopy test of the welded joint and parent material. Three optimization techniques are used in this study to validate the experimental results namely Taguchi method, Analysis of variance (ANOVA) and Artificial Neural Network (ANN). Taguchi L16 orthogonal array are used to identify the most effective input parameters which affect the energy absorption behaviour. Percentage contribution of individual input parameters analyzed by ANOVA method and also ANN was performed for non-linear mapping of the input and output parameters which are influenced by compression test. Experimental results have been validated with the optimization technique results and found to be in good agreement with them.

This paper discusses the possibility of developing a lightweight self-compacting concrete (SCC) with self-curing capabilities. In this regard, a supplementary cementitious material metakaolin, a presoaked lightweight expanded clay aggregate (LECA), and a chemical agent, superabsorbent polymer (SAP), were incorporated in developing a self-compacting self-curing concrete possessing a target strength of 60 MPa through experimental investigations, and the results are reported. The research includes an analysis of basic material properties of constituent materials including fresh properties of concrete and mechanical properties such as compressive and splitting tensile strength. It was inferred from the experimental results that utilization of self-curing agents in SCC has enhanced the mechanical properties when compared with conventional SCC mix. In particular, a combination of 0.3% SAP and 15% LECA gave the optimum strength values. The optimum usage limit of both the materials is presented in this study, and the results prove that SCC can be used as an alternate resource without disturbing the natural resources.
