Formation Mechanism of Microstructure during Static Recrystallization of Pure Nickel

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Evolution of Microstructure in Pure Nickel during Processing for Grain Boundary Engineering

Grain boundary engineered (GBE) materials have improved properties that are associated with the high fraction special Σ3 n boundaries in the microstructure, where n = 1, 2, or 3. Previous experimental studies with high purity nickel before and after GBE thermomechanical processing have shown that the fraction of Σ3 boundaries increased by at least factor of two [1]. Electron backscatter diffrac...

Dynamic Recrystallization by Necklace Mechanism During Hot Deformation of 316 Stainless Steel

The aim of this study is to investigate the nucleation of new grains by necklacing mechanism during dynamic recrystallization (DRX). The material used is 316 stainless steel. In order to modeling the deformation behavior during hot rolling, one-hit compression tests were performed at temperature range of 950-1100 °C with strain rates of 0.01-1s-1. The result shows that at the tempera...
