A significant increase in the research activity dedicated to high manganese TWIP steels has occurred during the past five years, motivated by the breakthrough combination of strength and ductility possessed by these alloys. Here a review of the relations between microstructure and mechanical properties is presented focusing on plasticity mechanisms, strain-hardening, yield stress, texture, fracture and fatigue. This summarized knowledge explains why TWIP steel metallurgy is currently a topic of great practical interest and fundamental importance. Finally, this publication indicates some of the main avenues for future investigations required in order to sustain the quality and the dynamism in this field.

Solidification microstructures and solid-state parallels: Recent developments, future directions

Over the past few decades, optical fibers have been widely deployed to implement various applications in high-speed long-distance telecommunication, optical imaging, ultrafast lasers, and optical sensors. Distributed optical fiber sensors characterized by spatially resolved measurements along a single continuous strand of optical fiber have undergone significant improvements in underlying technologies and application scenarios, representing the highest state of the art in optical sensing. This work is focused on a review of three types of distributed optical fiber sensors which are based on Rayleigh, Brillouin, and Raman scattering, and use various demodulation schemes, including optical time-domain reflectometry, optical frequency-domain reflectometry, and related schemes. Recent developments of various distributed optical fiber sensors to provide simultaneous measurements of multiple parameters are analyzed based on their sensing performance, revealing an inherent trade-off between performance parameters such as sensing range, spatial resolution, and sensing resolution. This review highlights the latest progress in distributed optical fiber sensors with an emphasis on energy applications such as energy infrastructure monitoring, power generation system monitoring, oil and gas pipeline monitoring, and geothermal process monitoring. This review aims to clarify challenges and limitations of distributed optical fiber sensors with the goal of providing a pathway to push the limits in distributed optical fiber sensing for practical applications.

Distributed optical fiber sensing: Review and perspective

Comprehensive utilization and environmental risks of coal gangue: A review

An H13 (high-strength, low-ductility) tool steel die will fail due to compressive high cycle fatigue. If the die is manufactured by direct metal deposition and layered with Inconel-718 (low-strength, high-ductility), it may impact the mechanical properties of the material. Hardness tests, micro-tensile tests, and micro-compression tests were used to analyze the mechanical properties of this additive manufactured layered metal while observing real-time morphology changes on the surface. Energy dispersive spectroscopy was also performed to determine where failure tended to occur within the Inconel-718 material. The hardness was lower than expected, as was the ultimate tensile strength, yield strength, modulus of elasticity, and strain at failure. Each tensile test failed within the Inconel-718 layer. A sample designed to have a single thin middle layer of Inconel-718 sandwiched by H13 enabled the visual recording of crack initiation and propagation under a tensile load using a confocal scanning laser microscope.

Vanadium redox data for petroleum coke combustion and gasification

Carbon feedstocks used in power, chemical and metallurgical industries typically contain numerous minerals or impurities that liquefy during high temperature processing to form slag as a byproduct. Slags have many industrial applications, for example, as construction materials and for element recovery. In addition to other variables, the extent of slag utilization is dependent on its composition and post treatments. In this work, the influence of temperature and phosphorus additions on phase evolution in coal slag was investigated. Synthetic slag mixtures with varying AlPO4 contents (0–14 wt%) were heated from 1380–1470 °C in air, then water-quenched to preserve the phases formed. SEM/EDS, XRF and XRD analyses were performed before/after testing to gain insight about slag chemistry and phases present. It was found that coal slag exhibited a large solubility of phosphorous, affecting morphology of mullite formed under the conditions studied. Results obtained and their significance are discussed.

The Influence of Phosphorous Additions on Phase Evolution in Molten Synthetic Coal Slag

The disclosure relates to a method for concentrating rare earth elements (REEs) from a coal byproduct. The method includes mixing the coal byproduct input with aluminum phosphate, sulfur and/or other compounds used as an additive; heating the coal byproduct input in air for a period of 3 minutes or longer at a temperature above a liquid starting temperature of the coal byproduct input, forming a molten coal byproduct; cooling the molten coal byproduct at a rate slower than critical glass transition cooling rate of the melt, forming REE phosphate product; heating the coal byproduct input above the liquid starting temperature of the coal byproduct after REE phosphate product is formed; and cooling the coal byproduct input at a rate faster than the critical glass transition cooling rate of the melt, minimizing forming unwanted solids.
