Smart Store (Purchase Materials): https://smartstore.naver.com/skyopen93 [Raf Machinery Story] General Mechanical Engineer Written Exam - Mechanical Materials (6) - Heat Treatment Hello everyone ^^~ This lecture is about quenching and tempering, which are part of the heat treatment section. I recorded it. ㅎㅎ I don't think I can cover the heat treatment section all at once, so I'll split it into 2-3 lectures, so please keep that in mind. ^^ Have a great day! ^^! #GeneralMechanicalEngineer #Written Exam #RafMechanicalStory #MechanicalMaterials #Quenching #Tempering #Cooling
