Abstract

PURPOSE: To reduce the erosion of a crucible and a change in the composition of an Mn alloy obtd. by casting, especially an Mn-Al-C magnet alloy by coating the inner wall of the crucible with Al.
CONSTITUTION: The inner wall of a crucible 4 made of oxide such as alumina is coated with Al 5 by application, spraying or other method. When Al 1, Mn 1 and C 3 as starting materials are irregularly packed into the crucible 4 and melted, the degree of erosion of the crucible and a change in the composition of the resulting alloy are remarkably reduced. The reason for the effects is considered to be that the Al layer 5 avoids the direct contact of molten Mn with the crucible and prevents the erosion of the crucible due to Mn.
