Spinodally hardened Copper-Nickel-Tin alloys have been under development for over 40 years. With considerable development effort, the ToughMet® class of Copper-Nickel-Tin alloys have become materials of commerce. One wrought temper, ToughMet® 3 AT110 (UNS C72900), has become the material of choice in high performance wear-critical applications. In preparation for AMS and MMPDS design allowables listing, substantial testing data was generated, including basic tensile and compression mechanical properties, pin bearing performance and shear strength over a wide rod and tube diameter size range.
Property performance will be described in detail and an initial overview of basic work hardening and fracture characteristics will be presented, including key inputs to modeling and design.
Summary: Property performance of wrought Cu-15Ni-8Sn spinodally strengthened alloy (ToughMetŪ AT110 (C72900)) is described in detail and an initial overview of basic work hardening and fracture characteristics will be presented, including key inputs to modeling and design.
