Effect of Process Parameters on Friction Properties of AISI 304 Steel Sheet during Strip Drawing Test

steel research international, EarlyView.
This study investigates how drawing process parameters affect the tribological behavior of AISI 304 steel sheet. Under lubricated conditions, increasing normal force, drawing speed, and countersamples roughness reduces the coefficient of friction by up to 21%.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Scheduling optimization of optical lens polishing

International Transactions in Operational Research, EarlyView.
Abstract Optical systems have achieved notable progress in focusing and imaging technologies; however, manual grinding remains indispensable, resulting in elevated costs, extended timelines, and inefficiencies. These difficulties are compounded by operational constraints, uneven machine utilization, and risks of order delays and escalating expenses ...

Influence of magnetic property for workpiece on thickness of removal and modified layers in large-area EB irradiation

Nihon Kikai Gakkai ronbunshu, 2019
In a large-area electron beam (EB) irradiation method developed recently, the large-area EB with high energy density can be obtained without focusing the beam. It can be used for melting and evaporating metal surface instantly.

Additive Manufacturing of Hot Work Tool Steel by Laser Powder Bed Fusion Utilizing Powder Mixtures Including Grinding Chips: Assessing Chemical Homogeneity and Achievable Hardness

Advanced Engineering Materials, Volume 28, Issue 1, January 2026.
Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.
