# # arev:/usr/local/unicat/unireq/beamreq/req00107.txt # UNICAT Member Beam Time Request #107 # created Thu Mar 30 11:24:32 CST 2000 # collaboration: No days: 1 description: We are interested in acquiring USAXS data from a series of nickel based superalloys that have undergone thermal exposure at high temperatures for various periods of time. The objective of this work is to characterize the population of gamma prime precipitates and carbides in forged Waspaloy as a function of thermal exposure. Complementary analytical methods (SEM, TEM, impedance specroscopy) are underway to further characterize the microstructure. equipment+required: USAXS experiment: USAXS of Waspaloy hazards: none name: Pete Jemian new+request: on nonmembers: Rosario Gerhardt, Georgia Institute of Technology station: 33ID-D unacceptable+dates: I am unavailable May 10 - May 14 and evening of May 24. This experiment is best scheduled in conjunction with a "batch" of USAXS experiments. Such as immediately following request #105. #QUERY_STRING: #REMOTE_HOST: user9.uni.aps.anl.gov #REMOTE_ADDR: 164.54.216.59 #CONTENT_LENGTH: 949 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.72 [en] (WinNT; I)
