Comparación de la microestructura y propiedades de impacto de dos materiales compuestos laminados de acero de ultraalto contenido de carbono

Abstract

Se procesaron mediante laminación en caliente dos materiales compuestos laminados de acero de ultraalto contenido de carbono (AUAC, 1,3%C) de seis capas cada uno: El primero está compuesto por tres capas de AUAC alternadas con tres capas de un acero microaleado, y el segundo con tres del mismo AUAC alternadas con tres de un acero suave. Se ha realizado un estudio de sus microestructuras, dureza Vickers y propiedades de impacto. Se han mejorado los valores de energía absorbida de los dos materiales compuestos laminados respecto al del AUAC. Palabras clave: Compuestos laminados, acero de ultraalto contenido de carbono, impacto Charpy. Microstructure and impact properties comparison of two ultrahigh carbon steel laminated compositesTwo ferrous laminated composites containing six layers have been processed by roll bonding. One of them consists of three layers of an ultrahigh carbon steel (1.3%C UHCS) interlayered with other three layers of a microalloyed steel. The other composite consists of three layers of UHCS and three layers of a mild steel. Microstructure, Vickers hardness and impact properties have been studied. The absorbed energy values of the two laminated composites were higher than that of the UHCS.

Effect of Hot Rolling on Bonding Characteristics and Impact Behavior of a Laminated Composite Material Based on UHCS-1.35 Pct C

“…Previous studies have manifested that multilayer composites constituted by UHCS have improved the mechanical behavior of their constituent materials, especially of the less tough UHCS. [1,[5][6][7][8][9][10][11][12][13] The excellent mechanical properties of these laminated composite materials are the result of controlling the bond processing conditions. For this purpose, a study of the influence of thermomechanical factors, in particular, the path of thickness reduction, on the interface bonding has been carried out.…”
