Abstract (sommario):
The foundation of materials science and engineering is the establishment of process–microstructure–property links, which in turn form the basis for materials and process development and optimization. At the heart of this is the characterization and quantification of the material’s microstructure. To date, microstructure quantification has traditionally involved a human deciding what to measure and included labor-intensive manual evaluation. Recent advancements in artificial intelligence (AI) and machine learning (ML) offer exciting new approaches to microstructural quantification, especially c

Abstract Wrought aluminum alloys are an attractive option in the quest for lightweight, recyclable, structural materials. Modern wrought aluminum alloys depend on control of complex microstructures to obtain their properties. This requires an understanding of the coupling between alloy composition, processing, and microstructure.

Abstract The unique combination of excellent mechanical and functional properties makes graphene an ideal component for high-performance ‘smart’ composites, which are sensitive to thermal, optical, electrical and mechanical excitations, hence being potential in application of a range of sensors.

Thus, graphene reinforced metal matrix composites (GMMCs) have long been regarded as potential prospects of nanotechnology applications. Recen

Recent advances in the analysis of microstructure is providing models and methods for treating the kinds of optimization problems that arise in the study of microstructure. The main advance has been the development of theory and methods for treating the case in which arbitrary microstructures compete for the minimum (or maximum). This contrasts for example with micromechanics in which the geometry of the microstructure is assumed, or assumed up to the choice of a few parameters, and then the optimization or stress analysis is carried out under severe geometric restrictions.

Given the strong recent interest in quenching-partitioning-tempering processed steels, the Niobium-alloyed medium carbon steel was investigated here. The microstructural observations and hardness were analyzed by optical microscope, transmission electron microscope, X-ray diffraction and hardness test. Results show that when quenched at 210°C and partitioned at 450°C, the quenching partitioning-tempering process leads to ultra fine-grained microstructures of martensite, retained austenite and carbides. And the microstructure and hardness changed differently with the increase of partitioned tim

For the purpose of investigating the microstructural evolution and the mechanical response under applied loads, a new phase field model based on the Ginzburg-Landau theory is developed by designing a free energy function with six potential wells that represent six martensite variants.

Abstract Grade 91 creep strength-enhanced ferritic steel is a critical material in power generation, widely used for high-temperature, high-pressure tubing and piping applications.

This microstructure, crucial for reliable service performance, is achieved through precise control of the manufacturing process, including steelmaking, hot forming, and final heat treatment.

Abstract Corrosion studies in laboratory ball mills and grinding environment simulations produce corrosion rates and total metal removal rates much lower than those recorded in operating production ball mills. The corrosion component of ball metal loss in commercial mills represents less than 10% of the total loss expressed as micrometers/hour of exposure in recent USBM tests. Such small absolute losses are consistent with ball metal loss measured in production ball mill marked ball wear tests to determine effects of corrosion and abrasion resisting properties of alloys in operating mills whic

Abstract (sommario):
Additive manufacturing (AM) has gained significant attention as a promising technique for producing complex-shaped components, particularly in the aerospace and biomedical industries. However, post-processing steps, such as heat treatment, can significantly influence the mechanical properties of additively manufactured parts. This research investigates the effect of supertransus heat treatment on the compressive behavior of Ti-6Al-4V (ELI) alloy produced through additive manufacturing. The specimens were subjected to a series of heat treatment cycles, including solution treatment and aging abo

Abstract TAF steel is a Japanese high-boron 10.5% Cr martensitic stainless steel known for its exceptional high-temperature creep strength. Its high boron content (300-400 ppm) limited practical applications due to reduced hot workability in large turbine components. Recent research suggests that increasing boron content while adjusting nitrogen levels could enhance creep properties by promoting fine vanadium carbonitride formation while preventing boron nitride formation. This study presents microstructural investigations, particularly using transmission electron microscopy, focusing on preci

Abstract (sommario):
Abstract The exploitation of unconventional reserves is pushing the limits of the materials selected in the oil and gas (O&G) industry. Precipitation hardened nickel alloys (PHNAs) such as UNS N07725 are typically used in applications that require high strength levels, corrosion, and environmentally assisted cracking resistance. However, unexpected cleavage failures of subsea components have been associated with hydrogen embrittlement (HE), calling into question the assumed superior properties of these alloys. Recent findings have linked the PHNAs’ HE field failures with the precipitation

Abstract (sommario):
Abstract High strength Nickel alloys are widely used in subsea and downhole O&G applications for their excellent combination of mechanical properties, toughness and corrosion resistance in sour environments. The trend in the O&G industry is for using higher strength materials for high pressure – high temperature service, however as strength increases materials may also become more susceptible to ambient temperature failure mechanisms associated with hydrogen absorption. In recent years resistance to Hydrogen Stress Cracking (HSC) and Hydrogen Embrittlement as well as sour corrosion res

Abstract (sommario):
Welding of micro-alloyed, high strength steels such as X100 poses a number of challenges due to, in part, the sensitivity of weld mechanical properties to the welding parameters such as heat input, preheat temperature, etc. For design purpose, it is often required that the mechanical properties of the welds overmatch those of the pipe materials in terms of yield strength, ductility, and toughness. In general, high strength pipe steels exhibit lower strain hardening capability, lower ductility, and increased anisotropy than the traditional lower grade steels. For these steels, when exposed to w

Abstract (sommario):
The focus in the present study was to establish whether there is a reasonable correlation between the Charpy Vee Notch (CVN) toughness and the non-destructive Potential Difference (PD) measurements of ferritic-pearlitic steels having a range of CVN toughness values. Complete material characterization was carried out for six steels procured for this program. The characterization included chemical analysis, microstructural information, tensile properties and CVN transition curves. In addition, most of the data including the CVN transition curves were available for five suitable pipe line steels

Abstract (sommario):
There is much to learn from the recent New Zealand and Japan earthquakes. These earthquakes produced differing levels of liquefaction-induced ground movements that damaged buildings, bridges, and buried utilities. Along with the often spectacular observations of infrastructure damage, there were many cases where well-built facilities located in areas of liquefaction-induced ground failure were not damaged. Researchers are working on characterizing and learning from these observations of both poor and good performance. The “Liquefaction-Induced Ground Movements Effects” workshop provided an opp
