heat-treating process where carbon is introduced into a solid iron alloy by heating above transformation temperature range while in contact with a carbonaceous material (solid, liquid, or gas form of carbon). Usually quenched to produce a hardened outer s

v: to cool heat-treated metal rapidly by immersion in an oil or water bath.

a crack in steel resulting from stresses produced during transformation from austentite to martensite.

heat treating requiring austenitization followed by cooling, under conditions that austenite turns into martensite.

n: oil injected into the liquid product from a cracking furnace with a view to cooling it rapidly and thus terminating the cracking reaction.
