Meeting last week in Tampa, Florida, the Steel Manufacturers Association Board of Directors elected eight officers to serve on the 2025-2027 SMA Executive Committee: Chair: Ty Garrison of CMC First Vice Chair: Matthew Ruckwardt of Cascade Steel Rolling Mills, Inc. and Radius Recycling Treasurer: Edward Goettl, J.D., of Optimus Steel LLC Immediate Past Chair: Mark Millett of Steel Dynamics, Inc Vice Chair at Large: Gregory Murphy of Nucor Corporation Vice Chair at Large: Charles Schmitt of SSAB Vice Chair at Large: Lenore Trammell of Big River Steel Vice Chair at Large: Michael Williams of Metallus Inc. The board also heard from outstanding guest speakers Nazak Nikakhtar, George David Banks, Christine Harbin, James Moss and Anthony Taccone. The next board meeting will take place during the SMA/MSCI Annual Members Conference in Frisco, Texas, March 3-5.

?? It's Tuesday evening, which means SMU's latest #sheet and #plate prices are out. Remember all those boring markets we had last fall? This is not one of them. ?? Some buyers are already hitting the "panic" button. Because the question is no longer whether prices will rise. Instead, it's how fast, how high, and for how long. (We've also got some concerns about availability creeping in.) ?? It's not just a stricter Trump 2.0 tariff regime that's sending prices higher. So too are more day-to-day things like spring maintenance outages at mills. ? How high do you think we'll go? And where does it stop? Hot band at $900/ton, a grand - more? (And, just as important, is there enough demand to make this sustainable? Or is it another of those price spikes the US is sort of notorious for?) https://lnkd.in/erkCPvjs

Lüders bands are localized bands of plastic deformation that appear in some metals, particularly in low-carbon steels and certain aluminum-magnesium alloys, when subjected to tensile stress. The phenomenon was first observed and described by Guillaume Piobert and W. Lüders. 1. Formation and Characteristics: a. Microstructural and Macroscopic Influence: The formation of Lüders bands is influenced by both the microscopic characteristics like grain size and crystal structure, and the macroscopic geometry of the material. For instance, a steel bar with a square cross-section tends to develop more Lüders bands than one with a circular cross-section. b. Yield Point Phenomenon: Lüders bands are associated with a yield point elongation where there's a sudden drop in stress after reaching the upper yield point, followed by a plateau in the stress-strain curve as the band propagates. This indicates the transition from elastic to plastic deformation. c. Propagation: The band typically starts at one end of a specimen and moves towards the other, with the front of the band often at an angle of 50-55 degrees to the specimen axis. Once the band has traveled through the entire specimen, uniform deformation resumes with positive strain hardening. 2. Experimental Observations: a. Stress-Strain Behavior: During tensile testing, the initiation of a Lüders band is marked by a yield point, followed by a drop in stress level where the band starts to propagate. This results in a serrated or noisy pattern in the stress-strain curve until the band crosses the entire length of the specimen. b. Material Instability: Lüders bands can lead to strain softening instabilities, where the deformation is not uniform, leading to potential issues in metal forming processes like deep drawing, where they might cause surface defects or aesthetic issues. 3. Practical Implications: a. In Metal Forming: In industries like automotive manufacturing, where sheet metals are used, the presence of Lüders bands can lead to undesirable surface features like stretcher-strain marks, potentially affecting product quality. To prevent this, materials might be pre-strained or cold rolled. b. Research and Mitigation: Studies have been conducted to understand and mitigate the effects of Lüders bands, especially in stainless steel cold rolling processes, where they can affect surface quality. Techniques like adjusting rolling parameters or material pre-treatment are explored to control or eliminate these bands. #metallurgy
