Beschreibung
Zusammenfassung:	FIELD: single-crystalline materials out of noble metal alloys. SUBSTANCE: single crystalline material is proposed which contains platinum, rhodium and iridium in the following relationship among components, fraction of total mass, %: rhodium - 3-15; iridium - 0.01-0.1; platinum - the balance. Purity of each of the components makes up not less than 99.99%. Alloy can additionally contains zirconium and/or hafnium. Single crystal is oriented. EFFECT: structure stability and enhanced strength characteristics of material under high temperature and increased pressure. 4 cl, 1 tbl, 1 ex
