Abstract Scope |
High temperature environments require corrosion resistant materials that can withstand extreme environments without failure. Control of microstructural properties through processing can lead to advanced radiation tolerant materials with desirable mechanical properties and enhanced corrosion resistance. For this work, processing methods pathways are examined for grain size control in binary Nickel-Chromium alloys. Different methods of grain refinement were performed to develop repeatable procedures for fabricating alloys with prescribed grain sizes between 1 and 100 microns. Samples of Nickel 8, 16, and 24 wt% Chromium were fabricated by arc melting. Samples were treated by hot rolling, cold rolling, and heat treatments between 1150ºC - 950ºC. Grains from the rolled samples were observed and compared to the as-melted samples. This poster will discuss manufacturing-property relationships between rolling, heat treatments, and grain size in Ni-Cr alloys, and present repeatable methods for tailoring prescribed microstructures in Ni-Cr alloys. |
