Comparative Study of Conventional And Minimum Quantity Lubrication During Machining 17-4PH Stainless Steel [PDF]

, 2015
Machining of different material with the conventional water soluble cutting oils have some challenges because of poor machinability characteristics. Many technology have been developed but minimum quantity lubrication (MQL) is the most frequent as it has

Pitting corrosion of 17-4PH stainless steel manufactured by laser beam melting [PDF]

, 2020
The pitting corrosion behaviour of a 17-4PH martensitic stainless steel (MSS) manufactured by power bed laser beam melting (LBM) was compared to that of a wrought MSS. More noble pitting potentials were measured for LBM samples, probably due to a smaller

Densification, deformation, and delamination during co‐sintering process of metal–ceramic laminates

Journal of the American Ceramic Society, Volume 108, Issue 2, February 2025.
Abstract Today, there is a high demand and increasing trend for multifunctional composite materials and components due to the combination of a wide range of favorable properties. However, undesired deformation leading to delamination, curvature, cracks, or even complete fracture frequently occurs during the co‐sintering process of metal–ceramic ...

Localized Laser Heat Treatment on AISI 1045 Steel Using a LPBF Laser

Engineering Reports, Volume 7, Issue 1, January 2025.
A LPBF laser was used to locally heat‐treat the surface of normalized AISI 1045 steel bars. While sections of overheating were seen, adaptations of previously published energy density models were able to determine valid parameters to create a hardened martensitic surface.

Genetic algorithm‐based approach for torque control and increased efficiency across an optimised speed range in switched reluctance drives

IET Electric Power Applications, Volume 18, Issue 12, Page 1818-1832, December 2024.
This paper presents a genetic algorithm design as a current profiling method in switched reluctance machines which eliminates torque ripple and minimises RMS current across the full machine speed range. The algorithm design introduces the use of novel ‘intentional’ greater‐than‐two‐phase overlap, which allows zero torque ripple operation at greater ...

Corrosion Fatigue of 17-4pH Stainless Steel in a Simulated Sea Water Solution

Journal of Advanced Materials in Engineering, 2019
Since martensitic precipitation hardened 17-4pH stainless steel has been widely used in corrosive environments, evaluation of its corrosion fatigue behavior is important. In this research, after microstructural studies, mechanical, corrosion, fatigue and

Understanding the Effects of Manufacturing Attributes on Damage Tolerance of Additively Manufactured Parts and Exploring Synergy Among Process‐Structure‐Properties. A Comprehensive Review

Engineering Reports, Volume 6, Issue 11, November 2024.
ABSTRACT Additive Manufacturing (AM) has revolutionized the production industry by offering design freedom with shorter lead times and reduced material wastage. However, the damage tolerance (DT) of AM parts is a significant concern due to their microstructural and geometric complexities, which affect their mechanical performance.

Experimental investigation on the tension lap splices used in the joints of precast RC foundation piles

Structural Concrete, Volume 25, Issue 5, Page 3468-3486, October 2024.
Abstract The joints between precast reinforced concrete pile segments in deep foundations are typically mechanically lockable. They include anchor bars embedded inside the ends of each segment, forming lap splices with the main bars. Because of their particular technology, these lap splices are somewhat different from traditional lap splices, as shown ...

Quinolone bioisosteres of phenolic GluN2B‐selective NMDA receptor antagonists

Archiv der Pharmazie, Volume 357, Issue 9, September 2024.
Novel antagonists of N‐methyl‐D‐aspartate (NMDA) receptors with GluN2B subunit were prepared by replacing the metabolically labile phenol of the potent lead compound Ro 25‐6981 by a quinolone system and incorporation of its flexible γ‐amino alcohol system into a cyclopentane ring.
