Arconic’s aluminum Micromill technology wins R&D 100 award
Source:
Arconic (formerly Alcoa), Pittsburgh, announces that R&D magazine has named Arconic's aluminum Micromill technology an R&D 100 Award winner. The technology reduces the production time to create rolled coil from hot metal from 20 days to 20 minutes. The Micromill's unique production process significantly changes the microstructure of the metal, allowing for higher formability, greater strength, and lighter weight at the same time. It produces metal that is 40% more formable and 30% stronger than today's incumbent automotive aluminum alloys, while meeting stringent surface quality requirements.
Automotive parts made with Micromill material are twice as formable and at least 30% lighter than parts made from high-strength steel.
"Arconic's Micromill material offers a unique combination of strength, weight reduction, and increased formability that was previously impossible," says Ray Kilmer, Arconic Chief Technology Officer. "Bringing these material benefits together changes the paradigm for auto makers, offering them unparalleled design freedom."
Micromill material debuted on Ford's best-selling vehicle, the 2016 F-150, and Ford continues to collaborate with Arconic under a joint development agreement announced last year.
Arconic received an R&D 100 Award in 2014 for its A951 bonding technology that enabled the historic shift to aluminum-intensive vehicles. Arconic estimates that it will grow its automotive sheet revenue approximately sixfold, from $229 million in 2013 to $1.3 billion in 2018.
This year's R&D 100 Awards were presented during the R&D 100 Conference in Washington, D.C., where top innovators in the R&D community come together each year to review the developments of the past year, provide insight into future forecasting, and foster a collaborative environment to share ideas and network with industry peers.

Computationally Optimized Heat Treatment Process wins R&D 100 Award
November 18, 2016
Source:
The National Energy Technology Laboratory (NETL), Pittsburgh, announces that its Computationally Optimized Homogenization Heat Treatment Process has been named a winner of the 2016 R&D 100 Awards. NETL's technology provides an easy method to optimize heat treatment to achieve the required degree of homogenization with a minimum of furnace time.
Conventional processes for homogenizing metal alloys are trial-and-error in their approach, resulting in increased process cost and limits to the possible paths that may be explored. The primary application for this technology is for alloys that are exposed to extreme environments, including heat-resistant alloys or those needing corrosion/oxidation resistance. A properly homogenized alloy will not only function better, but also will have an extended life cycle.
During solidification of any alloy, the elements segregate unevenly. This chemical segregation is unavoidable and results in non-uniform regions that negatively impact mechanical and physical properties. Even distribution of the alloying elements is necessary to achieve optimal performance for the specified application.
The computational approach to homogenization is based on kinetics of the chemical diffusion coefficient of each element to determine the homogenization cycle necessary to evenly distribute the elements that are susceptible to segregation. Conventional homogenization processes rely on a trial-and-error approach that results in the need for more experimentation and analysis. If the selected times and temperatures do not achieve the correct degree of homogenization, additional experimentation become necessary.
The Computationally Optimized Homogenization Heat Treatment Process is designed especially for alloys exposed to extreme environments, including heat-resistant alloys and those that require corrosion/oxidation resistance. Such alloys are typically in industries that service the aerospace, military, petrochemical, power generation, nuclear, structural, automotive. and instrumentation sectors.

One Minute Mentor: Effect of Cold Work on Grain Growth
November 14, 2016
Source:
Larger amounts of cold work refine the grain size during solution treatment, but smaller amounts of cold work can lead to critical grain growth. The effect of varying amounts of cold work on grain growth in A-286 during solution treating is illustrated in the graph.
The initial material was solution treated with a maximum grain size of ASTM 5. Cold working in the range of 1 to 5% caused excessive grain growth during subsequent solution treating at 1650°F. Above about 5% of cold work, critical grain growth does not occur, and the recrystallized grain size decreases with increasing cold work. Excessive grain growth, especially excessive localized grain growth, would likely degrade tensile properties.
Therefore, on parts subjected to cold or hot work prior to solution treating, the critical amount of work (about 1 to 6% cold work, depending on the alloy, and about 10% hot work) must be exceeded in all areas to avoid the growth of abnormally large grains. This rule applies to parts such as cold-headed bolts, spun or stretch-formed sheets, and parts formed by simple bending.
