This research outlines some of the experimental procedures and data analysis techniques used to examine the solidification of magnesium-aluminum and magnesium-zinc alloys using in-situ neutron diffraction. The magnesium alloys were melted in graphite crucibles and cooled from cooled from 650 to 300°C while being bombarded by neutrons at wavelength of 0.237 nm. The microstructure of the solidified magnesium alloy samples contained a zinc or aluminum enriched magnesium matrix and some coarse magnesium zinc or magnesium aluminum intermetallics. The neutron diffraction results were greatly improved by using larger sample sizes and incorporating sample oscillation and agitation. Improvement in fraction solid analysis was obtained by examining the neutron diffraction intensity of the samples well below their solidus temperatures.
