Microstructure of pearlite
WebThe results of optical microscopy (OM) images showed that the weld zones (WZ) of all three welds were composed of different ferritic morphologies, including allotriomorphic ferrite, Widmanstätten ferrite, and acicular ferrite, whereas the morphology of the heat-affected zone (HAZ) showed the various microstructures containing mostly ferrite and pearlite … WebThe pearlite content of an air-cooled microstructure ranges from zero in steels containing 0.02% carbon or less to 100% in steels containing 0.8% carbon. Thus, pearlite …

WebBased on my understanding of the diagram, at 727 ∘ C, you have 100% pearlite at C b = 0.76 % C and 0% pearlite at C a = 0.022 % C. W a then appears to be how far C o is between C a and C b, so W a should be the amount of pearlite. The units of C a, C b, and C o are % C b y m a s s.

Web30 jun. 2024 · The ferrite grains (white) and pearlite grains (dark stripes) can be seen. In comparison, a microstructure of a hypoeutectoid steel with a higher carbon content of 0.60 % (quenched and tempered steel C60) is shown. Due to the higher carbon concentration, the C60 also has a significantly higher pearlite content in the microstructure.
