Abstract

La invencion se refiere a un proceso para hacer una placa de molibdeno trabajada en direccion cruzada, incluyendo el proceso: (a) reducir molibdato de amonio y formar molibdeno metal en polvo; (b) consolidar un componente de molibdeno compuesto de molibdeno metal en polvo y un elemento de aleacion a una primera pieza, seleccionandose el elemento de aleacion del grupo que consta de titanio, zirconio, hafnio, carbono, oxido de lantano, y sus combinaciones; (c) tratar termicamente la primera pieza y someter la pieza a fuerzas termomecanicas en una primera direccion, y formar por ello una segunda pieza; (d) tratar termicamente la segunda pieza y someter la segunda pieza a fuerzas termomecanicas en una segunda direccion que difiere de la primera direccion; (e) someter la segunda pieza tratada termomecanicamente a un paso de tratamiento termico de recristalizacion, y formar por ello una pieza trabajada en direccion cruzada termotratada; y (f) someter la pieza trabajada en direccion cruzada termotratada a un paso de corte o un paso de maquinado, y formar por ello la placa de molibdeno trabajada en direccion cruzada. La invencion tambien se refiere a blancos de rayos X hechos con el proceso.
