In particular, we will investigate the movement of the boundaries near the intersection of three grains (i.e. a triple junction) resulting from thermal annealing. In addition, we will study the microstructure surrounding small, second phase Fe,Si precipitates embedded in the aluminum matrix in order to understand the effects of hard particles on boundary motions. equipment_required: experiment: Grain Boundary Motions in Bulk Aluminum foreign_nationals: Wenge Yang, Wenjun Liu hazards: A small, low-temperature (<400C), low-power (<15V, <3 amp) sample heater will be used minimumdays: 5 name: John Budai nonmembers: unacceptable_dates: Oct 1 – 6 Oct 24 Nov 6 – Nov 10 Nov 28 – Dec 11 z34ID_change_undulator: no z34ID_details: no z34ID_on_axis: no z34ID_parasitic: no z34ID_taper: yes #REMOTE_HOST: jdbg4.ornl.gov #REMOTE_ADDR: 160.91.48.40 #CONTENT_LENGTH: 1015 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 5.21; Mac_PowerPC)
