| 摘 要： | This paper discusses the microstructure of nickel-aluminium bronzes con-taining(9-10)wt% Al and(0.1～5)wt% Ni,in which three eutectoids may exist.Themorphologies of α+γ_2 and α+β'_2 are similar but the latter is finer.In the α+β'_2+γ_2eutectoid structure β'_2 is mainly concentrated at the α/β boundaries,while γ_2 is distrib-uted inside prior B regions.Both K-S and N-W orientation relationships exist betweenα and β'_2(or γ_2)in alloys consisting of α+β'_2 or α+γ_2.However,if the alloy consists ofα+β'_2+γ_2 eutectoid,the lattices of β'_2 and γ_2 are parallel,both of them have the N-Worientation relationship with α.
