Surface roughness prediction of AISI D2 tool steel during powder mixed EDM using supervised machine learning [PDF]

Scientific Reports
Surface integrity is one of the key elements used to judge the quality of machined surfaces, and surface roughness is one such quality parameter that determines the pass level of the machined product. In the present study, AISI D2 steel was machined with

MITIGATION OF AGRICULTURAL ENERGY REQUIREMENT IN BANGLADESH USING MICROALGAE PRODUCTION [PDF]

Journal of Mechanical Engineering and Sciences, 2013
A high quality joint between tool steel and stainless steel alloys is hard to achieve with the conventional welding process. In this study, a new process of joining semi-solid AISI D2 tool steel and AISI 304 stainless steel using a partial remelting ...

Pack Siliconizing Optimization of AISI D2 Tool Steel

Silicon, 2022
AbstractThe paper describes the pack siliconizing optimization procedure for AISI D2 tool steel. Pack siliconizing was performed by employing different treating temperatures (falling in the range 650–950 °C) and times (falling in the range 2–4 h). The siliconizing atmosphere was obtained through silicon (at 12 wt.%) with the addition of different ...

Microstructural and Mechanical Characterization of Ledeburitic AISI D2 Cold-Work Tool Steel in Semisolid Zones via Direct Partial Remelting Process

Journal of Manufacturing and Materials Processing, 2022
The success of the thixoforming process largely depends on the created microstructure, which must be globular in the liquid phase. The solid–liquid structural changes that occur on as-annealed D2 tool steel when it is subjected to the so-called DPRM are ...

Advanced Solid Lubrication with COK-47: Mechanistic Insights on the Role of Water and Performance Evaluation. [PDF]

Adv Sci (Weinh)
This study is the first to report the solid lubrication performance of the newly discovered Ti‐based MOF (COK‐47) powder. COK‐47 exhibits a remarkably lowest and most stable coefficient of friction compared to typical solid lubricants. The lubrication mechanism involves water molecules from the air participating in tribochemical reactions, forming an ...

Effect of Post-Heat Treatment on the AISI M4 Layer Deposited by Directed Energy Deposition

Metals, 2020
Currently, high-speed steel (HSS) powders are deposited locally on a metal surface through direct energy deposition (DED) onto hardface tool steel. Although the HSS powder enhances the hardness and the abrasion resistance of a metal surface, it makes the
