Welding the Inconel 718 Superalloy: Reduction of Micro-segregation and Laves Phases explores the day-to-day welding business in Alloy 718 and presents solutions to avoid or minimize micro-segregation. It considers the limitations of changing from lab scale models to actual production models and presents new technologies with proven experimental background. Various case studies are presented within the text, as well as proposed solutions backed by experimental evidence. Items previewed in this edition include enhanced cooling rates in the GTA welding process with cryogenic cooling and enhanced dendrite refinement using modified pulse waveform. This work will be useful to researchers from the aerospace, space, power generation, nuclear, and chemical industries, as well as students interested in superalloys and welding.

This volume explores recent research trends and achievements in environmental pollution remediation (e.g. water, air, soil), and compiles critical and constructive papers and reviews with a focus on advances in bioremediation and green technology solutions for waste minimization, waste management and pollution control. The book is timely, as the need for researchers and engineers to develop sustainable and green eco-friendly remediation technologies is increasing with a growing global population, stressed agricultural systems, and an environment impacted by climate change. A key focus of the book is on the efficient use of agricultural waste residues as viable substrates for creating materials for environmental clean-up, and the possible conversion of these pollutants to sustainable bioresources. The volume will be of interest to sustainability researchers, environmental engineers, industry managers and agricultural scientists.

This book offers an overview of the latest work in environmental remediation and waste management coming out of developing nations. It is split into two sections: one on state-of-the-art sustainable remediation approaches, and the other covering waste management for a cleaner environment The ten chapters in this book are structured as reviews that assimilate recent works in these areas; they provide a centralized resource for scholars in developing nations who are working in environmental remediation and waste management. The volume will be of interest to sustainability researchers, environmental engineers, industry managers and agricultural scientists.

Load bearing implants such as hip joints, knee joints and bone plates etc. are prone to failure from the conjoint effect of wear, fretting and corrosion from the movement of body. Modular junctions of hip implants consist of ball on a shaft which is under sliding conditions during body movements like walking etc. Fretting is experienced at ball and shaft contact. Fretting wear or fretting fatigue is a form of adhesive wear phenomenon wherein a small tangential oscillatory motion under certain contact pressure gradually erodes the surface and initiates crack within the contact leading to ultimate failure of the material under fatigue loading condition. Titanium alloys, Stainless steels and Co-Cr-Mo alloys are most commonly used for medical grade devices. Titanium alloys has high strength to weight ratio, superior biocompatibility and corrosion resistance compare to other materials. Fretting fatigue life of surface modified titanium alloys has improved compared to unmodified materials due to enhancement in surface properties and reduction in friction.
