Forming Mechanism of High-Speed Cold Roll Beating of Spline Tooth

Advances in Materials Science and Engineering, 2018
The spline tooth of ASTM 1045 was fabricated by high-speed cold roll-beating (HSCRB) process at room temperature. Microhardness of the spline tooth was examined by a nanoindenter.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Study of forming limit curves and mechanical properties of three-layered brass (CuZn10)/ low carbon steel (St14) /brass (CuZn10) composite considering the effect of annealing temperature

Journal of Materials Research and Technology, 2022
In this study, the effect of annealing temperature on the mechanical properties and formability of brass (CuZn10)/low carbon steel (St14)/brass (CuZn10) composite sheets fabricated by the cold roll bonding (CRB) process were studied.

Dimpling process in cold roll metal forming by finite element modelling and experimental validation

, 2014
The dimpling process is a novel cold-roll forming process that involves dimpling of a rolled flat strip prior to the roll forming operation. This is a process undertaken to enhance the material properties and subsequent products’ structural performance ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Numerical simulation of the roll levelling of dp1000 steel using a nonlinear combined hardening material model [PDF]

Computer Methods in Materials Science, 2014
The roll levelling is a forming process used to remove the residual stresses and imperfections of metal strips by means of plastic deformations. During the process the metal sheet is subjected to cyclic tension-compression deformations leading to a flat ...

Microstructure, texture, and mechanical properties of asymmetrically cold-rolled Ni1.5FeCrCu0.5 high-entropy alloy

Journal of Materials Research and Technology, 2022
This study deals with the microstructural evolution, texture development, and mechanical properties of the cold-rolled and annealed Ni1.5FeCrCu0.5 high-entropy alloy (HEA). In addition to symmetric rolling (SR), asymmetric rolling (AR) was performed with

Numerical Analysis of Circular Pre-notched U-Channel Section Distortions in Cold Roll-Forming Process [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2017
Cold roll forming is a process in which a metal sheet gets a desired section form by passing through a series of rotating rollers. Predicting the amount of the distortion in pre-notched cold formed sections still remains challenging in cold roll forming ...
