摘要: espanolLa constante necesidad de mejora en el sector aeronautico y aeroespacial introdujo uso materiales compuestos matriz metalica, para lograr propiedades excelentes con reduccion peso. Dadas las buenas caracteristicas del titanio, este fue considerado excelente candidato constituirse como metalica (TMCs); destacando la pulvimetalurgia principal metodo fabricacion, dada su versatilidad, menor coste mayor precision dimensional. En presente trabajo se realiza un analisis comparativo implicaciones finales material, segun polvo titanio empleado tipo refuerzo. Se estudian probetas fabricadas grado 1 o 5, varios tipos refuerzo ceramico porcentaje. Los tres refuerzos mas importantes campo los TMCs son B4C, TiC TiB2. Las muestras fabricaron empresa austriaca RHP-Technology GmbH, mediante tecnica compactacion polvos (Inductive Hot Pressing). Dichas piezas fueron analizadas varias tecnicas microscopia, ademas someterlas a diferentes ensayos determinar fisicas mecanicas importantes. conclusiones permitiran optimizar parametros encontrar asi nuevos que cumplan exigentes requisitos aeronautico.

Given its good properties, titanium was considered an candidate constitute highlighting powder metallurgy as main manufacturing method, given versatility, lower costs greater dimensional accuracy. In present work, comparative analysis influence final material is made, according used type reinforcement. Specimens were produced grade or different ceramic reinforcement percentages. The three most important reinforcements field are samples manufactured Austrian company via Inductive Pressing. specimens analyzed by several microscopy techniques, addition carrying out tests determine physical mechanical properties. conclusions will allow optimizing parameters, find new that fulfill demanding requirements sector.
