ANALYSIS THE INFLUENCE OF DRAWING PROCESS PARAMETERS ON THE AMOUNT OF RETAINED AUSTENITE IN TRIP STEEL WIRES

摘要

The paper presents a theoretical analysis of the process of drawing TRIP-effect steel wires involving simulation of the drawing process. The process was run following two variants, with small and large partial drafts for three drawing speeds: 1,11; 0,23 and 0,005 m/s. The investigations carried out allowed a relationship between the amount of retained austenite and strain intensity and strain rate to be established for TRIP steel wires drawn.
