Abstract (en)
The method of manufacture of a sabot component which comprises the steps of severing an aluminum workpiece (50) from bar stock, upsetting the workpiece in a first die, by axial force, to constitute a first preform (51) having a desired uneven mass distribution along the axis thereof, hot forging the first preform in a second die, by transverse force, to constitute a second preform (52) having an unsymmetrical mass distribution transverse to the axis thereof, hot forging the second preform in a third die, by transverse force, to constitute a stamping (60) having opposed unsymmetrical formed surfaces, solution heat treating the stamping to a "W" condition, freezing the stamping to render its metalography dormant, cold forging the stamping in the third die, artificially aging the stamping to a "T8" condition, trimming the stamping in a fourth die, and annodizing the trimmed stamping,
