Quantitative measuring of pearlite in carbon steels using electromagnetic sensor
Non-destructive Eddy current (EC) technique has long been used to detect discontinuities in materials. Recently, its application has been extended to characterize materials microstructure. In order to identify different microstructures, four plain carbon steel bars with different chemical compositions (AISI 1015, 1035, 1045 and 1080) were used in annealed condition. The pearlite percentage, car...
متن کاملDivorced Pearlite in Steels
Steels containing large carbon concentrations are used particularly when a large hardness is required, for example in the manufacture of components such as bearings. This, however, makes it difficult to shape or machine the alloys during the process of component manufacture unless they are first heat–treated into a softened condition. One method of achieving this economically is to generate a m...

متن کاملThree Dimensional Optical Microstructure Analysis of Ferrite and Pearlite Phases in a Medium Carbon Steel
This work presents a three dimensional microstructural analysis of medium carbon steels, based on serial sectioning using optical microscopy. The microstructural phases considered here are ferrite and pearlite. Typically conventional 2D microscopy is used to analyze these phases, with eddy current or ultrasonic methods as alternatives. Medium carbon steel samples were heat treated in a furnace ...
متن کاملDiffusion–Controlled Growth of Pearlite in Ternary Steels
A theory for the diffusion–controlled growth of pearlite in steels containing manganese is presented and assessed in the light of experimental data. Given the overwhelmingly rapid diffusivity that a substitutional solute has within the transformation front, the growth rate is found to be dominated by diffusion parallel to the interface with austenite as the rate controlling step. The relevant i...
