    Agitating the aluminum pot
    MIT researchers demonstrate that strong churning during hot liquid state can produce stronger, more uniformly structured large aluminum casts.

    Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product, with castings sometimes ending on the scrap heap. Controlling the distribution of strengthening elements to aluminum throughout a casting is thus key to reducing waste and improving product reliability.

    Over the past three years, MIT Assistant Professor of Metallurgy Antoine Allanore and his student Samuel R. Wagstaff [PhD '16] developed a new process that uses a turbulent jet to reduce this uneven distribution in aluminum alloy structures by 20 percent. This work was in collaboration with global aluminum processor Novelis. The researchers were able to pinpoint a single number - the "macrosegregation index" - that quantifies the difference between the ideal chemical makeup and the actual chemical makeup at specific points in the solidification process.

    Commercializing integrated photonics
    Technical groups, educators tackle plans for manufacturing computer chips with integrated optical devices and developing a regional workforce at AIM Photonics fall meeting.

    Leaders from industry, state government, and higher education focused on the best ways to create a robust, integrated-photonics manufacturing corridor along Interstate 90 from Boston to Rochester, N.Y., on the final day of the AIM Photonics fall meeting held at MIT Oct. 31 through Nov. 2, 2016."The meeting's presenters showed that Massachusetts has strong capability in integrated photonics today, and that community colleges, manufacturing extension partnership [MEP] programs, and small and medium enterprises can provide robust support to achieve the I-90 corridor for excellence in integrated photonics," says Julie Diop, program manager for AIM Photonics Academy at MIT. Integrated photonic systems use light pulses [photons], as well as electrical signals, to process and communicate data within the same integrated circuit.

    About MPC

    The goals of the Materials Processing Center are to unite the materials research community at MIT and to enhance Institute-industry interactions. Collaboration on research ventures, technology transfer, continuing education of industry personnel, and communication among industrial and governmental entities are our priorities. The MPC 
    Industry Collegium is a major vehicle for this collaboration. The MPC sponsors seminars and workshops, as well as a summer internship for talented undergraduates from universities across the U.S. We encourage interdisciplinary research collaborations and provide funds management assistance to faculty.
