RESISTENCIA A LA ABRASIÓN vs. RESISTENCIA AL IMPACTO DEL ACERO AISI 15B30, TEMPLADO + REVENIDO/ WEAR RESISTANCE vs. IMPACT RESISTANCE OF STEEL AISI 15B30, QUENCHED AND TEMPERED

SIERRA RESTREPO, HORACIO; TOBÓN, DIANA MARCELA
2007-11-01

Resumen en español Debido al bajo carbono de los aceros al boro, algunos fabricantes recomiendan el revenido como tratamiento opcional y otros sugieren que no es necesario. Puesto que los aceros al boro son muy utilizados en aplicaciones agrícolas donde tienen exigencias de desgaste e impacto, (p.ej. discos de arados), es, entonces, conveniente evaluar dichas propiedades del acero AISI 15B30 con temple y temple más revenido a diferentes temperaturas y contrastarlo con características del (mas) AISI 1030, obtenidas en condiciones similares. De los resultados obtenidos, se desprende que el revenido a 200ºC después del temple es beneficioso ya que la energía absorbida en el ensayo de impacto es el doble de la obtenida en probetas con solo temple, conservando las propiedades de dureza y resistencia a la abrasión. Resumen en inglés Due to the low carbon of boron steels, some factories recommend the tempering as optional and others suggest that it is unnecessary. Because boron steels are widely used in agricultural applications where they are exposed to wear and impact, as in plowing discs, it is then convenient to evaluate the properties of AISI 15B30 steel quenched and tempered at different temperatures and to contrast them with those obtained on steel AISI 1030 under similar conditions. From the o (mas) btained results, it can be seen that tempering at 200ºC produced twice the impact energy of the quenched sample without a decrease on resistance and hardness and a light decrease on abrasion resistance.

DEPENDENCIA DE LA TEMPLABILIDAD EN FUNCIÓN DEL GROSOR EN MATERIALES TERMOVISCOELASTICOS

Báiz, P.; Troyani, N. L.
2002-07-01

Resumen en español En el trabajo se examina la magnitud de los esfuerzos residuales que se obtiene al someter piezas de diversos tamaños de una clase de materiales termoviscoelásticos, los llamados termoreologicamente simples, a un cierto grado de templado. El procedimiento numérico utilizado en la parte mecánica del trabajo ( determinación de desplazamientos, deformaciones y esfuerzos) se realiza discretizando el dominio a través de elementos finitos; en la parte térmica transitoria (mas) la discretización espacial se realiza por diferencias finitas de espaciado no uniforme y la discretización temporal a través de un esquema Crank-Nicolson. El procedimiento es empleado para un cilindro infinito de vidrio flotado, determinándose que los esfuerzos residuales son más intensos para cilindros más gruesos. Este efecto, no presenta un límite claramente definido, identificándose una tendencia continuamente creciente. Resumen en inglés In this work the temperability of a certain class of thermoviscoelastic materials, called thermorheologically simple, is examined by determining the magnitude of the residual stresses when subjecting different size pieces to a particular tempering intensity (fast cooling). The numerical procedure employed in the work to determine the mechanical response (displacements, strains and stresses) is based on a discretization using displacement based finite elements. The evoluti (mas) on of temperature is determined by using a non uniform mesh finite difference scheme for the spatial dependency and through a time discretization based on a Crank-Nicolson procedure. The stated numerical scheme is employed in the cooling of an infinite cylinder of float glass. It was established that the magnitude of the residual stresses increases with size. This effect does not seem to show a clearly defined limit, rather, a continuously increasing tendency was determined.
