On machining of hardened AISI D2 steel with PCBN tools
Journal of Materials Processing Technology, 2006Abstract This paper describes an experimental investigation on machining of a difficult-to-cut material, AISI D2 steel of hardness 62 HRC with PCBN tools. It was found that the most feasible feeds and speeds fall in the ranges 0.08–0.20 mm/rev and 70–120 m/min, respectively and that most of the tested PCBN tools reached the end of life mainly due to ...

AISI D2 punch head damage: Fatigue and wear mechanism
Engineering Failure Analysis, 2021Abstract The purpose of this work is to analyze the damage of AISI D2 punch head whose main part is used halting production. The punch head failure could be categorized into three major types namely the swollen, the mated and the cracked punch. Furthermore, this study underlines the punch damage causes using the optical microscope and SEM so as to ...

On the refinement of carbide precipitates by cryotreatment in AISI D2 steel
Philosophical Magazine, 2009Refinement of carbide particles by cryotreatment is often proposed as a major factor for the improvement of wear resistance in tool steels. However, this proposition is not substantiated by experimental evidence. This has been examined in this report by (i) detailed micro-structural analyses of the nature, volume fraction, size, population density and ...

Structure-Property Correlation of Cryotreated AISI D2 Steel
Advanced Materials Research, 2010This study aims to reveal the underlying mechanism associated with the enhancement of wear resistance of tool steels by deep cryogenic treatment and to resolve the issue of reported varied degree of improvement in wear resistance through structure-property correlation of cryotreated vis-à-vis conventionally treated AISI D2 steel.

On the corrosion behavior of TiN-coated AISI D2 steel
Surface and Coatings Technology, 1999Abstract An extensive investigation on the corrosion behavior of the TiN-coated D2 tool steel was performed. It is demonstrated that the corrosion properties of the TiN-coated D2 steel are primarily determined by the synergetic effect of the packing factor and thickness associated with the coating.

Electrochemical boriding and characterization of AISI D2 tool steel
Thin Solid Films, 2011Abstract D2 is an air-hardening tool steel and due to its high chromium content provides very good protection against wear and oxidation, especially at elevated temperatures. Boriding of D2 steel can further enhance its surface mechanical and tribological properties.

Experimental Study in HSM of Hardened Steel AISI D2
Advanced Materials Research, 2009Hardened steel is widely used for good mechanical property, but its machinability is bad comparatively. It is efficient to enhance metal removed rate when high speed milling (HSM) hardened steel, but tool wear is rapid. In this paper, high-speed milling experiments were carried out for hardened steel with TiAlN coated tools.

Corrosion Behavior of TiN Coated AISI D2 Steel
2015In this study, the corrosion behaviors of nitride and titanium nitride (TiN) layers deposited on AISI D2 steel samples are reported. Steel was at first nitrided in a nitrogen and ammonia atmosphere at 575 °C for 8 h and then titanium nitride coating treatment was performed in the powder mixture consisting of ferro-titanium, ammonium chloride and ...

Influence of Cutting Edge Radius in Micromachining AISI D2
Applied Mechanics and Materials, 2013Chip formation is a dynamic process that is often non linear in nature. A chip may not form when the depth of cut is less than a minimum chip thickness. This paper presents an investigation of cutting edge radius effect on micromachining AISI D2 tool steel via simulation.

Tribocorrosion behavior of surface-modified AISI D2 steel
Surface and Coatings Technology, 2020Abstract Three different thermochemical coatings were obtained on the surface of an AISI D2 cold work tool steel under different process conditions through the use of boriding, titanizing, and borotitanizing (titanizing followed by boriding) treatments.
