METHOD FOR CONTROLLING METALLIC STRUCTURE

摘要

PURPOSE:To obtain a desired structure consisting of grains grown in one direction by fixing each alloy body to be treated in dies having a simple external shape and by heating the body through the dies so as to make the temp. of the body uniform. CONSTITUTION:Dies 2 having axial symmetry and a simple external shape such as the shape of a round or square rod are prepd. Each body 1 to be heat treated is fixed in the dies 2. The body 1 is zone-heated together with the dies 2 by moving a heating part 3 such as a heating coil. Thus, a desired structure consisting of grains grown in one direction is obtd.
