Reading ttt diagrams with reheat
WebIn materials science, time–temperature–transformation (TTT) diagrams express the conversion rates of equal phase transfor-mations during cooling. [1 ] The most prominent materials for which TTT diagrams are used are steels, alloys, [2 ] metallic-glasses, [3 , 4 ] glasses, and glass-ceramics. [5–9 ] They all have in Web--Given Values-- Time Temperature Transformation Diagram: = 1050 Steel Heat Treatment: = Quench to 750 F hold for 20 seconds then quench to RT Instructions: For the following problems utilize the listed TTT Diagram from your Equation Booklet. The treatment begins with austenitizing temperature. RT = Room Tempearture.
