Abstract
The subject of this study was the influence of local deformation on carbide particles size, shape and distribution in bars of diameter ranging from ϕ 150 mm to ϕ 40 mm made of S 6-5-2 ESR and SC 0-5-1-2Nb high-speed steels.
The local deformations distribution on the transverse cross-sections of the bars forged in radial-forging machine was calculated by means of the finite elements method (thermo-mechanical modelling). Carbide particles size, shape and distribution were evaluated with an image analyser MORPHOPERICOLOR.
The empirical equations showing the effect of local deformation on stereological and morphological parameters of carbide particles were determined. The "structural maps" showing the variation of microstructure on the transverse cross-section of the bars were plotted.
The final result of this work is a programme for selection of forging parameters (local deformation distribution) with respect to the initial values of carbide particles stereological parameters as well as to the assumed microstructure variation on transverse cross-section of the final product.
Keywords : computer simulation and modelling, plastic working, quantitative metallography, tools alloys
