En el Grupo de Propiedades Mec\u00e1nicas y Transformaciones de Fase <\/strong>se\u00a0estudian las transformaciones de fase, difusivas y martens\u00edticas, y el comportamiento mec\u00e1nico de metales y aleaciones. Los materiales en estudio son particularmente aleaciones con memoria de forma base Cobre y aleaciones termoenvejecibles base Aluminio, tanto aleaciones comerciales como fabricadas en el Laboratorio con materiales de alta pureza, a partir de las cuales se obtienen monocristales<\/p>\n

Las l\u00edneas de trabajo actuales del grupo son:<\/p><\/div>\n<\/div>\n
