High Voltage, EarlyView.ABSTRACT As a commonly used bushing current‐carrying structure in recent years, contactor‐type electrical connection parts operate in a complex environment of electric, thermal and chemical corrosion for extended periods. With the increase of ultra‐high voltage (UHV) transmission capacity, its operating environment faces more stringent challenges, and ...

Uncovering hidden bias in neutron diffraction residual strain measurements
Journal of Applied Crystallography, EarlyView.This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Australian Journal of Public Administration, EarlyView.Abstract Remarkably little is known about what factors drive success or failure in foreign policy. In part, this is because there is little fundamental agreement on what constitutes success or failure in this domain in the first place. This article engages with these shortcomings by comparing two similar regional order‐building initiatives overseen by ...

Journal of the Royal Anthropological Institute, EarlyView.In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

Friction stir processing (FSP) is variant of friction stir welding (FSW) process, which is a solid-state material processing technique. Materials for specialized applications are desired to have certain selective properties which are not possible to achieve from the traditional alloy processes, such as a combination of hardness and toughness, that can ...

The intrinsic nature of friction stir process has two basic components as highlighted in previous chapters, material flow and microstructural evolution. The development of friction stir processing as a generic metallurgical tool for microstructural modification and a broader manufacturing technology is connected to these.

Introduction to Friction Welding, Friction Stir Welding and Friction Stir Processing
2020Manufacturing of product requires the joining of materials at one point or the other during the product manufacturing process. There are a number of joining processes that are used namely: temporary and permanent joining processes. Welding is a permanent welding process with two basic types: solid-state welding and fusion welding.

Thermal history analysis of friction stir processed and submerged friction stir processed aluminum
Materials Science and Engineering: A, 2007Abstract In this research, equations are developed to model the rate of heat input from different geometries of friction stir processing (FSP) tools. The model is then compared with actual heat input obtained from embedded thermocouples within the stirred region.

Friction stir vibration welding process: modified version of friction stir welding process
The International Journal of Advanced Manufacturing Technology, 2016In the current research, a new method is applied to modify the conventional friction stir welding (FSW) process. Fixture, which fixes the workpieces, is shaken mechanically during FSW in a direction normal to weld line in order to increase the straining of weld region material.
