1. Of or relating to an alloy or steel containing less of the alloying element than the eutectic composition; having a carbon content below the eutectoid point.
Usage: metallurgy; technical

Examples

• Hypoeutectoid steel contains less than 0.77% carbon by weight.
• The microstructure of hypoeutectoid alloys typically consists of ferrite and pearlite.
• Engineers often prefer hypoeutectoid compositions for their improved ductility.
• A hypoeutectoid steel will transform differently during cooling than a hypereutectoid steel.
