High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. Cryogenic treatment can be used to enhance the tool life. Studies on cryogenically treated (CT) cutting tools show micro structural changes in the material that can influence the life of the tools significantly. This paper primarily reports performance of CT HSS tools as compared to untreated (UT) ...

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral indus...

In the field of mechanical engineering, engineers are always looking for ways to improve the properties of materials. Cryogenic treatment of tooling steels is a proven technology to increase wear resistance and extend intervals between component replacements. The main idea of this paper is to apply Taguchi method to optimize cutting parameters in turning operation using cryogenic treated (CT) a...

To achieve better structural performance, lesser damage along with minimum residual displacements is a main objective of earthquake resistant design. In ordinary steel reinforced concrete frames, chances of severe damage because of the lower strength of conventional steel are always present during strong earthquakes. With the invention of high-strength steel (HSS) it can be anticipated that its...

The present study applied extended Taguchi method through a case study in straight turning of mild steel bar using HSS tool for the optimization of process param. The study aimed at evaluating the best process environment which could simultaneously satisfy requirements of both quality as well as productivity with special emphasis on reduction of cutting tool flank wear, because reduction in fla...

nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. to reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

To enhance the cutting performance of high speed steel(HSS) end mill, single and multilayer coating is applied on substrated HSS mill. Coating material reduces force enhances resistance against abrasive wear. This paper presents physical vapour deposition(PVD) technology machinability PVD coated The mills are fifteen times better than uncoated mill proposed conditions. TiAlN monolayer mills(fut...

SKD 11 tool steel is among the most popular metals in mold industries for making different kinds of cold work molds and dies with high accuracy and long service life. The demand for higher quality, lower manufacturing costs, particularly the environmentally friendly characteristics, have provided the stimuli for manufacturers and researchers to find alternative solutions. An excellent media is ...

Reinforcement grades higher than 75 ksi (520 MPa) are not allowed in members that form plastic hinges due to a lack of information on material characteristics and on the seismic performance of columns constructed with high-strength steel (HSS) reinforcement. This research investigated the performance of reinforced concrete columns containing Grade 80 (minimum yield strength of 80 ksi [550 MPa])...

Abstract In general, Physical Vapor Deposition (PVD)-TiN coated High Speed Steel (HSS) endmills used to machine carbon steels can perform better at high cutting speeds compared with uncoated tools resulting in better surface finish and longer tool life. Flank wear is believed to be the main wear type that leads to shorten the life of these cutting tools. In this study, the roles of the coating ...
