The key obstacle to industrial scale magnesium rolling is the element’s inherently poor formability at room temperature. To address this challenge, the search is on for new magnesium alloys that feature improved formability along with novel rolling techniques. This article describes R&D activities at CanmetMaterials aimed at expanding manufacturing capabilities of magnesium-based sheet materials for future applications in transport vehicles.

An examination of a bearing failure due to mismatched and incomplete flame hardening shows the need to work with heat treaters for proper selection and application. The article includes a case study of a large bearing raceway that failed due to incomplete austenitization.

A multicomponent thermal spray coating system resists pick-up of contaminants that can cause flaws on heat treated strip surface.

A new design and welding process may extend the life of furnace rolls in hot-dip coating lines, which often fail in less than one year. This article is a case study of analysis of a failed furnace roll that led to a proposed improved design to extend component life.

Alloy developers worldwide have struggled to create creep-resistant alumina-forming, iron-based austenitic stainless steels for use as high-temperature structural alloys, but with limited success in balancing alloy cost, oxidation, and creep resistance. This article describes the research and development of a novel cast alumina-forming austenitic stainless steel. This work won the prestigious Engineering Materials Achievement Award presented at IMAT 2023 in Detroit.

With the opening of Testbed 80, the largest engine testing facility in the world, Rolls-Royce plans to use its unique capabilities to accelerate the journey toward sustainable aviation technologies supported by the intelligent use of materials.

Developing a disciplined approach to standardizing special processes and introducing new technologies is key to eliminating defects in thermal spray applications.

The initial steps in the art of manufacturing cymbals are discussed from ancient times through the modern era, including copper smelting, alloying copper and tin, pouring the molten metal into ingots, and processing the ingots by hand-hammering or rolling a finished blank.

Outdoor enclosures for telecom equipment are often constructed from powder-coated aluminum, but with appropriate surface treatments, hot and cold rolled steel can serve in the same capacity at a lower cost. This article, the first of a two-part series, discusses the intrinsic corrosion behavior of hot and cold rolled steel and how it can be modified through galvanizing and aluminizing treatments. Part 2, scheduled for the October 2012 issue of AM&P , covers nonmetallic surface treatments and presents corrosion test results.

In recognition of ASM International's 100-year anniversary, AM&P highlights historic events and technological advancements that occurred over the course of those years. This issue covers the first decade, from 1913 to 1933, which includes the awarding of a patent for the nitriding process, the invention of the Rockwell hardness tester, the commissioning of "Big Bertha" in WWI, the inaugural edition of the ASM Handbook, and the start-up of America's first continuous hot rolling mill in Ashland, Ky.

News about ASM members, chapters, events, awards, conferences, affiliates, and other society activities. Topics include: ASM committee and council chairs appointed for 2019-2020; ASM Connect platform for member engagement rolls out; ASM Materials Genome Toolkit Program supported by the NIST-funded Center for Hierarchical Materials Design (CHiMaD); new equipment added to the ASM training laboratories; contributor spotlight for Erik Mueller; professional profile for Janet Gbur.

By 1875, the Bessemer steel industry had spread across the country from eastern Pennsylvania to St. Louis. Pittsburgh was home to a number of plants with multiple converters and the required blast furnaces and rolling mills to serve the growing demand for steel rails and beams. This article describes how Andrew Carnegie developed his steel empire with Pittsburgh as the epicenter.

The ability to produce bulk metallic nanolaminates has greatly expanded the potential structural applications for these materials, motivating investigations into formability, joining techniques, and deformation behavior. This article presents an overview of both the accumulative roll bonding process and the deformation behavior for copper-niobium nanolaminates. This entry won the Jacquet-Lucas Award for Best in Show at the 2014 International Metallographic Contest.

This article provides a brief review of thermal spray technology along with examples of where and how it used in steelmaking equipment and operations.

This article describes the laser beam texturing (LBT) process and how LBT materials differ from those produced using traditional surface texturing techniques.

Early humans had no knowledge of iron. Unlike gold, silver, and copper, iron does not exist as a native metal. This article explores the early days of wrought iron production.

Outdoor enclosures for telecom equipment are often made from aluminum, but with the protective treatments described in this two-part article series, inexpensive steels can serve in the same capacity. Zinc-based galvanizing and aluminizing treatments, which were presented in Part 1, may be used alone or together with corrosion-resistant paints, pretreatments, and sealants described here. This article also assesses the corrosion resistance and adhesion properties of different combinations of steels, coatings, and pretreatments by means of salt fog spray testing.

Because residual stress has a significant impact on engine component service life, understanding its cause helps optimize fabrication processes to ensure quality. X-ray diffraction is often the only viable technique to measure residual stresses at certain failure-critical locations. This article gives some guidelines for XRD analysis to understand and control residual stresses in processing of engine components.

Significant advancements in metallurgy were highlighted at a special symposium presented at the Materials Science & Technology 2016 conference in Salt Lake City. This article summarizes the topics presented. All six speakers shared examples of the importance of understanding how the specific manufacturing process affects microstructure development in metals. The fundamental understanding of microstructure allows metallurgists to select manufacturing processes and schedules to tailor the microstructure, and therefore mechanical properties and performance, for a particular component.

From 1988 to 2008, the minimill industry added 25 million tons annual capacity—25% of the total U.S. steel market.
