... the similarity of names, and avoid confusing the two types of embrittlement. (An older name for TE is temper brittleness.) Temper embrittlement occurs when tempering in the high-temperature range of approximately 600 °C (1100 °F). It is not a significant problem, because it can be avoided easily by quenching...
