and Cu matrix was determined as [011]*Cu*//[011]*Cu*5*Zr*, ( − 31<sup>−</sup> 1)*Cu*//( − 11<sup>−</sup> 1)*Cu*5*Zr*.

(3) Nearly spherical particles were identified as a Cr9.1Si0.9 intermetallic phase with a b.c.c structure, having a typical N–W orientation relationship with the Cu matrix. Another coarse particle with a lath shape was confirmed as a kind of (Cu, Cr, Zr, Ni, Si)-rich complex compound.
