Symposium Defects and Properties of Cast Metals IV
Presentation Title Using Inoculation and Solidification Rate Adjustments to Control Intermetallic Distribution in Nickel Gear Bronze
Author(s) Samuel W. Plummer, Milo Kral
On-Site Speaker (Planned) Samuel W. Plummer
Abstract Scope Numerous casting defects and mechanical specification failures in continuously cast and centrifugally cast CuSn12Ni (similar to C91700) nickel gear bronze have been attributed to segregation and a detrimental distribution of a tin-rich intermetallic phase, the so-called δ-phase Cu41Sn11. While relatively large particles and/or inhomogeneous distribution of δ-phase are detrimental to properties, the phase contributes to the hardness and wear resistance of the alloy, so there is an opportunity to optimize volume fraction and particle size. This research investigated solidification rate and numerous inoculating agents for their effectiveness in confining the δ-phase to relatively fine, evenly-distrbuted particles.
