時効硬化 (じこうこうか) Japanese meaning | Kotomora
Meanings 1
noun
age hardening ; precipitation hardening
chemistry
Technical term in materials science and metallurgy. Refers to a heat treatment process where a material's hardness and strength increase over time after quenching or cold working, often due to the formation of fine precipitates.
時じ 効こう 硬こう 化か 処しょ 理り を 施ほどこ し た 鋼こう 材ざい は 、 高たか い 耐たい 久きゅう 性せい を 示しめ す 。
Steel that has undergone precipitation hardening treatment exhibits high durability.
Kanji 効 merit, efficacy, efficiency 化 change, take the form of, influence Similar words 析せき 出しゅつ 硬こう 化か 析出硬化 is a synonym for precipitation hardening, often used interchangeably with 時効硬化 in metallurgy. 時効硬化 emphasizes the time-dependent aspect of the hardening process.
焼やき 入い れ 焼入れ (quenching) is a rapid cooling process that often precedes age hardening. While quenching alone can increase hardness, age hardening further strengthens the material through controlled precipitation over time.
Etymology Compound of 時効 (じこう, 'aging' or 'time-dependent effect') and 硬化 (こうか, 'hardening'). The term is a direct calque from English 'age hardening' or 'precipitation hardening', reflecting the metallurgical process where material properties change over time.
