The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is...

17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...

Deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the final tempering treatment to enhance the wear resistance and hardness of the steels. In this study, the effects of the deep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studied using the wear testing machine and polarization and impeda...

Over the past decade, many computational studies have explored the mechanics of normal indentation. Quantitative relationships have been well established between the load–displacement hysteresis response and material properties. By contrast, very few studies have investigated broad quantitative aspects of the effects of material properties, especially plastic deformation characteristics, on the...

The friction and wear behaviour of ZrO*-Y203, Zr02-Y203--Ce02 and ZrQ--A1203 composite ceramics against hardened steel AISI-52100 were investigated using a pin on plate configuration under reciprocating motion. The reproducibility of the results was examined in this configuration. Wear characteristics were separated into system and material contributions. Under the conditions used, all the cera...

An experimental investigation into material transfer and wear has been performed for the case of a ferrite probe sliding at high speeds (between 25 cm/set and 1250 cm/set) and low loads (10 gm) on a steel disk, a nickel plated disk, and a polymercoated disk, the latter containing finely dispersed abrasive particles. Autoradiographic methods together with microdensitometer analysis have been app...

mo40 low-alloy steels are mostly used to produce industrial components such as crane wheels whichare exposed to abrasive wear. however, during working conditions, their wear resistance is reduced aftera while due to its low hardness. with increasing abrasive wear, the dimensions of components decreaseand they need to be repaired for surface modification. in this regard, hard overlay coatings ar...

The world standards for conventional ceramic hardness have varying requirements for control of loading rate during the indentation cycle. A literature review suggests that loading rate may affect measured hardness in some instances. In view of the uncertainty over this issue, new experiments over a range of indentation loading rates were performed on a steel, sintered silicon carbide, and an al...

The wear failure mode of a paver spiral blade was simulated by EDEM software. High-manganese steel, medium chromium alloy and high steel were selected as matrix materials; SiC particles WC surface particle reinforcement the prepared EPC process. performance mechanism analyzed microstructure, hardness, impact, pin disk, erosion test, morphology. Modeling with software applying discrete element a...

Wear experiments have shown that when the applied normal stress exceeds a critical value, a transition occurs from the regime of mild wear to that of adhesive wear. As a result, the wear rate of particle-reinforced aluminium composites increases by a hundred-fold. Based on dislocation and delamination theories, a criterion is proposed for determining the critical transition load, and a quantita...
