Description
急冷処理後の、約595℃の温度で約8時間の間の焼戻し処理;および次いで、
空気中での冷却処理をさらに含む。
固溶化温度がβ変態点−30℃ではなく、β変態点−20℃(約980℃)であったこと;および
熱処理方法を通じて使用された急冷速度が、かなり速く:200℃/分ではなく400℃/分であり、例えば油による急冷ではなく水による急冷を用い、場合により最も厚い区域を予め機械加工することによって、材料が極度に厚くなることを避けるように注意することを除き、前述の熱処理を受けていた。
β変態点−30℃におけるのではなく、β変態点−20℃(約980℃)における固溶化;および
固溶化は、1時間ではなく、8時間行われた。
