The nondendritic semi-solid slurry preparation of high chromium cast iron Cr20Mo2
has been studied in this paper. The experiments show that the proeutectic austenitic
particles are more spherical under a larger stirring power condition, even if the stirring
time is shorter, while the proeutectic austenitic particles are not very much spherical
under a smaller stirring power condition and some proeutectic austenitic dendrites
also exist, even if the stirring time is very long. The experiments also show that when
stirred for 5{6 minutes under the test condition, the semi-solid slurry with 40vol.%{
50vol.% solid fraction and spherical proeutectic austenite in the size of 50{80¹m can
be obtained.
