The present paper is an effort to culminate the status, scopes and challenges in the development of ferrous metal matrix composites (FMMCs). The FMMCs are old but less in use than the non-ferrous metal matrix composites (NFMMCs), as far as literature and actual applications are concerned. Therefore, this stimulates the exploration of the reasons be...

Electrical discharge machining (EDM) is commonly used to machine hard-to-cut materials without physical contact between the workpiece and the tool. It works on a dominant thermal mechanism in which the material is eroded by melting and vaporising through numerous high-energy sparks. This paper presents a thorough literature review about the researc...

In last few years, the global coating industries and scientific have introduced superhydrophobic coating with high water repellency. Photovoltaic (PV) panels installation in the dusty regions results in the reduction of its power output because the soil deposition on it resists the conversion of light into power. Thus, in order to prevent the above...

Wire arc additive manufacturing (WAAM) is an imperative method for fabricating 3D metallic parts. By the large, additive manufacturing (AM) innovation is utilized to prevail over the restriction of conventional subtractive manufacturing (SM) for manufacturing larger parts with a low buy-to-fly ratio. There are mainly three heat sources utilized in...

The major factors affecting the process of combustion in a single cylinder diesel engine is in-cylinder fluid flow characteristics. Better fuel-air mixing and combustion rates in diesel engine are primarily enhanced by the fluid flow. The fluid flow prior to combustion process in DI diesel engines travel through induction process and further gets i...

The present work is an attempt to model the components of specific grinding energy in a pragmatic manner. This work explores the contribution of specific energy constituents such as shearing, primary rubbing, secondary rubbing, and ploughing energy while grinding Inconel 718 (IN-718) superalloy. Specific shearing energy has been calculated using th...

Grinding nowadays is extensively used for machining of superalloys. Inconel 718 is a Ni-based superalloy which is known as difficult to grind material (DTG) due to its inherent properties like high hardness, high hot strength, severe strain hardening and low thermal conductivity. In the present work, grindability of Inconel 718 using conventional a...

This work describes the procedure for the design of a multi-hole extrusion process. For the same sizes of the holes, the ram force in a single-hole extrusion process is more than in a multi-hole extrusion process. Therefore, a simplified upper bound and slab method analysis has been carried out for a single-hole extrusion process. The ram and die p...
