Wire Arc Additive Manufacturing (WAAM) is the process of used to fabricate material samples by deposition of material which is in wire form at high temperature ER-4043 Aluminium wire is deposited on substrate steel plate and predicted the properties by following Taguchi orthogonal Array. It reduces the complexity occurs by conventional process in fabricating a large size, complex shape components. In the present investigation, the optimized multi-responses by Orthogonal Array (OA) which are strength and hardness values obtained during WAAM process for nine samples are evaluated to presage the influence of process parameters through Grey Relational Analysis (GRA) followed by Taguchi method.

The development of radiation attenuation materials with lean cross-sections is the need of the hour. However, the inherent threat of radiations accompanying these processes is of major concern. Thus, in an attempt to shield unnecessary radiations, several novel materials have been fabricated alongside the conventional materials available. Yet, there is a need for cost-effective, efficient shielding materials that have good mechanical strength and effective shielding properties. The present work investigates ceramic composite behaviors and radiation shielding capacity reinforced with lead oxide nano-powder. Developed nano-lead-based cement composites were subjected to mechanical tests to determine flexural and compressive strengths to check their suitability for structural applications. Further, the gamma attenuation test of the composites was conducted to determine their neutron absorption capacity. The addition of nano-leadoxide in the control beams was varied from 0.7 to 0.95 and 1 wt.% of the ceramic matrix. The percentage of nano-leadoxide that gives the best results in both enhanced properties and economic aspects was determined to be 0.6 wt.% of the cement.

Gear is a power transmitting element among the rotating shafts by means of progressive meeting of projections which is identified as teeth. The purpose of the gear is transmitting torque (power) among rotating shafts when the central distance between the shafts is comparatively less.The main aim of the paper is to Design and Analysis of a helical gear for marine applications, by using empirical formulas and Calculation, from the data to draw a 3D model helical gear by using Pro/Engineer Software and the Structural and Thermal Analysis done by the Simulation Software (ANSYS).Structural and thermal analysis is done using two materials Nickel Chromium Molybdenum Alloy Steel and Aluminum Alloy A360. Structural analysis and thermal analysis is done to conform to the Displacement, Von Mises Stress, and thermal properties related nodal temperature, thermal gradient and thermal flux.
