“…However, tool wear is also one of the major challenges, and limited studies are published on this topic [ 99 , 118 , 180 , 181 , 182 , 183 , 184 ]. In fact, tool wear can be avoided by adopting cryogenic treatment [ 185 , 186 , 187 , 188 , 189 ] of the tool materials. Both fixtures and backing plates play a key role in heat balance across the cross-section [ 190 ] of the joints.…”

Joining immiscible materials such as copper and stainless steel together is a significant concern due to distinct mechanical and metallurgical properties across the joint line, such as melting points, the coefficient of linear thermal expansion, and thermal conductivity. The joint properties of copper to stainless steel welds are in great demand for various mechanical components of the international thermonuclear experimental reactor, ultra-high vacuum system, plan wave linear-accelerator or linac structure, and heat exchanger. These dissimilar-metals joints offer excellent flexibility in design and production, leading to a robust structure for many cutting-edge applications. Hence, the present article reviews the copper to stainless steel joining mechanism under different solid-state processing conditions. The present understanding says that defect-free strong joints between the dissimilar metals are systematically possible. Apart from this understanding, the authors have identified and highlighted the gaps in the research exploration to date. Moreover, a sustainable methodology to achieve a desirable weld of copper to stainless steel depends on favorable processing conditions.

“…The results showed that down cut provided greater performance while full immersion extended tool life in compared to half immersion. Thakur et al [23] witnessed that, at prominent speed, tool wear was mostly influenced by tool-chip contact length. According to Choudhury and El-Baradie [24], uncoated carbide tool exhibited the superior surface quality relative to coated carbide tools at inferior cutting speed (50 m/min), while using coated tool, 39.79% reduction in cutting force was observed at the maximum cutting speed [25].…”

Analyzing and comprehending cutting process mechanisms is a crucial step in creating a cost-effective, long-lasting, and safe machining process.In modern manufacturing, it is very challenging to achieve a high surface finish product with high dimensional accuracy. To reduce the high production cost as well as for the sustainable manufacturing selection of both cutting tool materials and cutting environments is necessary. Nowadays high-temperature alloys are in very demand in industries like power generation, gas turbines, and chemical processing. Superalloys are recognised as a significant problem in a high-temperature work environment with the sophisticated material technology in space and aviation industries. At the time of machining of these superalloys, a high amount of heat developed at the cutting area which affects the microstructure of the work specimen and also the cutting inserts. To minimize that excess heat, researchers and manufacturing industries are adopting different cooling lubrication techniques. When the lubricant penetrated the cutting region, the temperature is reduced since cooling effect. Several studies focus on the optimization of individual performance features in the machining processes and in recent past, Super-alloys and cutting materials like ceramic, carbide, and hybrid tools are gaining popularity. Since the application of the superalloy in various sectors is ever- increasing, therefore it is necessary to evaluate a machining behavior during the experimental investigation. In this contemporary review, the effects of various cooling and lubrication strategy on machining outputs will be discussed considering the sustainable and greenway of manufacturing.

“…High-speed steel (HSS) was a widely used tool steel which is characterized by its high hardness, great wear resistance, superior impact toughness, and excellent cutting ability [ 1 , 2 , 3 ]. Deep cryogenic treatment (DCT) can further optimize the microstructure and enhance the mechanical properties of HSS to meet the efficiency and quality requirements of modern cutting [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ].

High-speed steel is widely used for cutting tools due to its convenience of preparation and cost-effectiveness. Previous research has shown that deep cryogenic treatments improve the mechanical properties of high-speed steel, due to the transformation of the residual austenite and the precipitation of carbide, while few studies have researched martensitic changes. The variations in martensite multi-level microstructures in AISI M35 high-speed steel, treated over different deep cryogenic time periods, were investigated in this study. Meanwhile, the effect of these variations on the mechanical properties of the selected steel was discussed. It was found that prolonging deep cryogenic time facilitated an increase in dislocation, low-angle grain boundary, and the coincident-site lattice boundary (especially the twin boundary) of martensite. The size of the martensite block (db) and lath (dl) decreased with deep cryogenic time. However, the effect on the microstructure was limited when the cryogenic treatment time exceeded 5 h. The increase in dislocation decreased the temperature for carbide precipitation and promoted fine carbide precipitation during tempering. The refinement of martensite multi-level microstructures and the greater precipitation of fine carbides gave the tempered specimens excellent impact toughness. The impact toughness of the tempered samples undergoing deep cryogenic treatment for more than 5 h was about 32% higher than the sample without deep cryogenic treatment.
