N2 - The high tensile strength copper-based alloys without Be are investigated. Results indicates that the tensile strength of thermomechanically processed and aged Cu-9Ni-6Sn alloy is higher than 900 MPa. It also shows that Cu-11Al alloy shows the precipitation of the α-proeutectoid in deformed β phase during the thermomechanical processing, causing a refinement of the microstructure. The small grain size of α-proeutectoid and β′-martensite phases and the strong strain hardening of α-proeutectoid phase account for the superior tensile strength of this alloy.
