金屬手工具的製作過程中，經常需要進行一系列的熱處理技術，以提高其硬度和耐久性。其中固溶處理是指將金屬加熱至其過飽和溫度，然後迅速冷卻，以溶解合金元素，提高材料的強度。退火是將金屬加熱至一定溫度，然後緩慢冷卻，以消除內部應力和改善韌性。淬火回火則是先經過淬火使金屬迅速冷卻，然後進行回火處理以提高其靭性和韌性。這些熱處理工藝對於金屬手工具的性能具有重要影響，使其更加堅固耐用。

Solution treatment refers to heating the metal to its supersaturated temperature and then rapidly cooling it to dissolve alloying elements and increase material strength. Annealing involves heating the metal to a certain temperature and then slowly cooling it to eliminate internal stresses and improve ductility. Quenching and tempering first involves quenching the metal to cool it rapidly and then tempering it to enhance its toughness and ductility. These heat treatment processes have a significant impact on the performance of metal hand tools, making them more robust and durable.
