WebNecip Fazıl Yilmaz. In the present study, V-shaped arc welding of the AISI 1045 steel is modeled by using 2D Finite Element Model (FEM). The temperature distribution, … WebCarbon steel parts of only small size (5 mm for AISI 1080) are austempered due to very high cooling rates needed to avoid pearlitic transformation. Austempered steels are superior to the quenched and tempered products when the hardness is in the range of HRC 50-55. Table 3.1 compares the properties for these two heat treatments in 0.75% carbon ...

Isothermal transformation diagrams (also known as time-temperature-transformation (TTT) diagrams) are plots of temperature versus time (usually on a logarithmic scale). They are generated from percentage transformation-vs time measurements, and are useful for understanding the transformations of an alloy steel at elevated temperatures.
