Nodular cast iron austempered has superior mechanical properties than other family members of nodular cast iron in relation to properties like machinability, tensile strength, wear resistance, toughness and ductility.The first stage of this research seeks nodular cast iron base material of a specific composition. For this purpose, the nodular cast iron is obtained in a 10 kg crucible furnace using both heat energy of propane gas (LPG) and magnesium alloy as a catalytic agent which is added at the bottom of the molten material as inoculant silicon (ferrosilicon). The liquid metal mold casting sand is wedge shaped. The material microstructure evaluation was performed in both tin and thick areas as follows: a) On the wedge area of minor thickness, fringe pelletizing graphite, fringes with pearlite matrix and steatite were detected. b) On the wedge area of major thickness, gra...

Las fundiciones nodulares austemperadas poseen propiedades mecánicas más superiores que otros miembros de la familia de las fundiciones nodulares en lo que se refieren a aquinabilidad, resistencia a la tracción, resistencia al desgaste, tenacidad y ductilidad. En la primera etapa de esta investigación se busca obtener el material base hierro fundido nodular de una composición específica. Con este propósito, e l hierro fundido nodular será obtenido en un horno de crisol de 10 kg., empleando la energía calorífica que proviene del quemado del gas de propano (GLP), utilizando aleación de magnesio como nodulizante el cual se introducirá en el fondo del material fundido y como inoculante silicio (ferrosilico). El metal líquido colado en molde arena en forma de cuña. La evaluación de la microestructura del material fue realizada en la zona de menor grosor y en...
