Microstructural and Mechanical Analysis of Seamless Pipes Made of Superaustenitic Stainless Steel Using Cross-Roll Piercing and Elongation

Journal of Manufacturing and Materials Processing, 2023
The cross-roll piercing and elongation (CPE) is a forming process performed at high temperatures and high strain rates. The final product quality is strongly dependent on its microstructure.

Effects of Grain Refinement on the Corrosion Behaviour of Microalloyed Steel in Sulphuric Acid Solutions

International Journal of Electrochemical Science, 2012
Microalloyed steels have been widely used in many applications, particularly in car bodies and other engineering parts. This is because these steels are characterized by their high strength and high ductility.

Bifunctional Passivation Strategy to Achieve Stable CsPbBr₃ Nanocrystals with Drastically Reduced Thermal-Quenching

, 2020
The thermal quenching behavior (temperature-dependent luminescence) has severely hindered the practical applications of CsPbX3 nanocrystals. Here, we find that a simple surface treatment using ammonium hexafluorosilicate (AHFS, (NH4)2SiF6) can ...

Non Photochemical Quenching mechanism in higher plants and in the unicellular alga Chlamydomonas reinhardtii [PDF]

, 2010
Light is a necessary ecological factor for oxygenic photoautotrophic organisms. Plants and algae require light for life but it can sometimes become a limiting factor or even cause stress events.

Precipitation Versus Partitioning Kinetics during the Quenching of Low-Carbon Martensitic Steels

Metals, 2020
Low-carbon, low-alloy steels undergo auto-tempering and carbon partitioning to austenite during quenching to martensite. The microstructures of two such steels quenched at two cooling rates have been evaluated using electron microscopy to characterise ...

Quenching and blowup problems for reaction diffusion equations [PDF]

, 2004
In this thesis we study quenching and blowup problems for reaction diffusion equations with Cauchy-Dirichlet data. We give sufficient conditions for certain reaction terms under which quenching or blowup can occur.

Enhancement in the Hardness and Corrosion Resistance of Mild Steel Surfaces by Nickel-Chromium Addition and Rapid Cooling After Welding

Journal of Applied Science and Engineering
In a corrosive environment, it is crucial to increase the hardness and corrosion resistance of mild steel bucket excavators. Making a hard layer of nickel-chromium (NiCr) alloy by the deposition method is one of the many approaches to achieve this.

A SERS quenching method for the sensitive determination of insulin

, 2020
In this work, we utilise the disulphide bond structure of insulin and a new benzothiazole Raman probe for the detection of human insulin using surface‐enhanced Raman spectroscopy (SERS).
