Most Fe-Ni meteorites are a two phase mixture of fcc and bcc phases. We secured six samples of Fe contents from 95% to 85% all of which were thought to contain small amounts of carbon. We found no Snoek peaks in the as-received condition for any of the six. After being heated and cooled, three showed pronounced Snoek peaks, three showed no Snoek peaks.
