Abstract

"LIGAS PARA ALTAS TEMPERATURAS E ARTIGOS FEITOS E REPARADOS COM ESTAS LIGAS". São apresentados uma liga, um artigo compreendendo a liga, e métodos para a manufatura e o reparo de um artigo empregando a liga. A liga compreende, em percentual atómico, pelo menos cerca de 50% de rádio, até cerca de 49% de um material, cerca de 1% a cerca de 15% de um segundo material, e até cerca de 10% de um terceiro material. O primeiro material compreende pelo menos um entre paládio, platina, irídio e combinações destes. O segundo material compreende pelo menos um entre tungstênio, rénio e combinações destes. O terceiro material compreende ao menos um entre rutênio, crómio e combinações destes. A liga compreende uma fase estruturada de tipo A1 a temperaturas maiores que cerca de 1000<198> C, em uma quantidade de pelo menos cerca de 90% em volume.
