Copper effects in mechanical properties of rapidly solidified Sn–Pb–Sb Babbitt bearing alloys

The mechanical behavior of Sn–Pb–Sb Babbitt bearing alloys has been modified with 5 wt% copper and processed by melt spinning technique. Results on the rapid solidification structure and the ribbon indentation creep tests are discussed. The stress exponent values in the range 2.11–2.75 indicate that grain boundary sliding is the possible mechanism during room-temperature creep deformation of melt-spun bearing alloys.
