Journal ArticleDOI
High Strain Rate Superplasticity in a Friction Stir Processed 7075 Al Alloy
TL;DR: In this article, the authors reported the first results using friction stir processing (FSP) for aluminum alloys and showed that FSP of a commercial 7075 Al alloy resulted in significant enhancement of superplastic properties.
Journal ArticleDOI
Radiation damage tolerant nanomaterials
Irene J. Beyerlein,Alfredo Caro,Michael J. Demkowicz,Nathan A. Mara,Amit Misra,Blas P. Uberuaga +5 more
TL;DR: In this article, the authors present an approach for processing bulk nanocomposites containing interfaces that are stable under irradiation, which is the key factor in reducing the damage and imparting stability in certain nanomaterials under conditions where bulk materials exhibit void swelling and/or embrittlement.
Journal ArticleDOI
Design of Radiation Tolerant Materials Via Interface Engineering
Weizhong Han,Michael J. Demkowicz,Nathan A. Mara,Engang Fu,Subhasis Sinha,Anthony D. Rollett,Yongqiang Wang,John S. Carpenter,Irene J. Beyerlein,Amit Misra +9 more
TL;DR: A novel interface engineering strategy is proposed to simultaneously achieve superior irradiation tolerance, high strength, and high thermal stability in bulk nanolayered composites of a model face- centered-cubic (Cu)/body-centered-cUBic (Nb) system.
Journal ArticleDOI
High-strength and thermally stable bulk nanolayered composites due to twin-induced interfaces
Shijian Zheng,Irene J. Beyerlein,John S. Carpenter,Keonwook Kang,Keonwook Kang,Jian Wang,Weizhong Han,Nathan A. Mara +7 more
TL;DR: This discovery proves that interfaces can be designed within bulk nanostructured composites to radically outperform previously prepared bulk nanocrystalline materials, with respect to both mechanical and thermal stability.
Journal ArticleDOI
Deformability of ultrahigh strength 5 nm Cu/Nb nanolayered composites
TL;DR: In this article, micropillar compression testing has been used to obtain stress-strain curves for sputter-deposited Cu-Nb nanolaminate composites with nominal bilayer thickness of 10nm.
