Low Activation Joining of SiC/SiC Composites for Fusion Applications: Tape Casting TiC+Si Powders
Charles H. Henager,Richard J. Kurtz,Nathan L. Canfield,Yongsoon Shin,Walter G. Luscher,Jirgal Mansurov,Timothy J. Roosendaal,Brennan Borlaug +7 more
TL;DR: In this paper, the use of SiC composites in fusion environments likely requires joining of plates using reactive joining or brazing, and one promising reactive joining method uses solid-state displacement reactions between Si and TiC to produce Ti3SiC2 + SiC.
Journal ArticleDOI
High ductility aluminum alloy made from powder by friction extrusion
Scott Whalen,Matthew J. Olszta,Christian Roach,Jens T. Darsell,Daniel Graff,Md. Reza-E-Rabby,Timothy J. Roosendaal,Wayne K. Daye,Tom Pelletiers,Suveen N. Mathaudhu,Suveen N. Mathaudhu,Nicole R. Overman +11 more
TL;DR: In this article, the authors used friction extrusion to consolidate and extrude aluminum alloy powder into bulk nanostructured rods, which exhibited 450 MPa ultimate tensile strength, 380 MPa yield strength, and 15.7% elongation at ambient temperature.
Journal ArticleDOI
Polymer-Cement Composites with Self-Healing Ability for Geothermal and Fossil Energy Applications
M. Ian Childers,Manh-Thuong Nguyen,Kenton A. Rod,Phillip K. Koech,Wooyong Um,Jaehun Chun,Vassiliki Alexandra Glezakou,Diana T. Linn,Timothy J. Roosendaal,Thomas W. Wietsma,Nicolas J. Huerta,Barbara Kutchko,Carlos Fernandez +12 more
TL;DR: In this article, a polymer-cement composite with remarkable self-healing ability that maintains the required properties of typical wellbore cements and may be stable at most geothermal temperatures is presented.
Journal ArticleDOI
High speed manufacturing of aluminum alloy 7075 tubing by Shear Assisted Processing and Extrusion (ShAPE)
Scott Whalen,Matthew J. Olszta,Md. Reza-E-Rabby,Timothy J. Roosendaal,Tianhao Wang,Darrell R. Herling,Brandon Scott Taysom,Sarah Suffield,Nicole R. Overman +8 more
TL;DR: In this paper, shear assisted processing and extrusion (ShAPE) was used to extrude aluminum alloy 7075 tubing at speeds up to 12.2m/min without surface tearing.
Journal ArticleDOI
Physical and electrical properties of melt-spun Fe-Si (3–8 wt.%) soft magnetic ribbons
Nicole R. Overman,Xiujuan Jiang,Ravi K. Kukkadapu,Trevor Clark,Timothy J. Roosendaal,Gregory W. Coffey,Jeffrey E. Shield,Suveen N. Mathaudhu,Suveen N. Mathaudhu +8 more
TL;DR: In this paper, Fe-Si alloys ranging from 3 to 8% Si were rapidly solidified using melt spinning and wheel speeds of 30 and 40m/s were employed to vary cooling rates.
