Document Type and Number:
WIPO Patent Application WO/2018/117135
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an Ir alloy which exhibits excellent high-temperature strength, while ensuring oxidation wear resistance at high temperatures. A heat-resistant Ir alloy according to the present invention is characterized by containing 5-30 mass% of Rh, 0.3-5 mass% of an element group A that is composed of at least one of Ta and Re, and 0-5 mass% of an element group B that is composed of at least one of Co, Cr and Ni, with the total of the element group A and the element group B being 5 mass% or less. This heat-resistant Ir alloy is also characterized in that in cases where the element group A is composed of Re, the element group B is composed only of Co or Cr, or is alternatively composed of two or more elements selected from among Co, Cr and Ni.
