Abstract

Provided is a brazing alloy powder with which the development of defect in a brazed portion is suppressed and which enables an increase in the joint strength of the portion to be joined. Also provided is a brazed joined component having a high joint strength of the portion to be joined. The brazing alloy powder includes particles which include 55 mass % or more of at least one element selected from Ni, Fe, and Co. The alloy powder includes not less than 10% alloy particles having an amorphous phase. In addition, d90≦60 μm, where d90 is the grain diameter indicating 90% in an integral volume distribution curve according to a laser diffraction scattering method. The joined component includes a plurality of members joined with a brazing material including the brazing alloy powder.
