Nuclear Materials Research at NC State University
主讲人 : Prof. K. Linga. Murty
A brief outline of the research activities during the past 3 decades in the Nuclear Materials Research group at NC State University will be summarized that comprise of creep mechanisms in materials, reliability of solders in electronic packaging, radiation embrittlement of ferritic steels, anisotropic biaxial creep of hcp ls with emphasis on Zircaloy cladding, condition monitoring of structural materials using automated ball indentation, NMR study of dynamical behavior of point and line defects during deformation and radiation effects in nanocrystalline materials. The talk will highlight the current and past collaborative research programs in USA and abroad ending with the current research programs on transitions in creep mechanisms of low c/a-ratio hcp ls, creep and creep-fatigue of alloy 709 and SCC of stainless steel welds in canisters for dry storage of spent nuclear fuel.
Dr. Murty is the Professor in the Department of Nuclear Engineering and Department of Materials Science and Engineering, has extensive experience in Mechanical llurgy and is the author of more than 125 technical papers on creep, fatigue, and fracture of ls. He received his M.S. and Ph.D. degrees from the Cornell University, Ithaca, NY in 1967 and 1970.
His experience and interests include failure analysis, corrosion and SCC, structure-property relation, effect of aggressive environment and neutron exposure on the mechanical properties and fracture characteristics of ls, embrittlement of nuclear pressure vessel steels, formability of ls, superplasticity, development of crystallographic texture and the resulting anisotropy, etc. The materials studied include aluminum alloys (Al-Mg, Al-Zn), pressure vessel steels, zirconium alloys (Zircaloy), stainless steels, turbine materials (Ni superalloys), lead alloys (Pb-Sn), copper-gold alloys, alkali halides, high purity iron and molybdenum, hcp ls (Zr, Ti, Mg, Zn and their alloys), ferritic steels, WC-Co tool materials and alkali halides. NDE and NDT for life assessment (and condition monitoring) of structural materials in nuclear reactors (PV steels, piping, SSs, superalloys, micro-electronic solders, etc.) using automated ball indentation (ABI); in-situ NMR investigation of the dynamical behavior of point and line defects; reliability of solders in electronic packaging, and processing (ball milling and SPD) and characterization of ultrafine grain ls. He has published more than 340 technical papers.
His work has earned him numerous honors, including the American Nuclear Society’s (ANS) ‘Mishima’ Award and NC State’s Alcoa Foundation Research Achievement Award. He is a Fellow of ANS and ASM International. In honor of his outstanding contribution, a mini-symposium on ‘Creep, Deformation, Texture, Nano and Nuclear Materials (radiation effects and modeling)’ was organized at the Plasticity conference in Big Island, Hawaii in Jan, 2016.
