Indentation creep and mechanical properties of quaternary Sn–Sb based alloys

Creep behavior of Sn–Sb based quaternary alloys have been investigated by indentation method at room temperature. Stress exponent values have been determined using Mulheam–Tabor method and the calculated exponents are in good agreement with the values of Sn based reported in the literature. The stress exponent values in the range of 3.39–5.12. Elastic modulus and internal friction of Sn–Sb based alloys have been studied and analyzed.

This research investigated creep behavior/creep resistance (stress exponent), elastic modulus and internal friction of Sn–Sb–Cu based bearing alloys. Stress exponent of used alloys in the range from 3.39 to 5.12 and that agrees with Geranmayeh and Kangooie. Elastic modulus and internal friction used alloys are affected by changing on β Sn matrix microstructure Geranmayeh and El-Bediwi.Figure optionsDownload as PowerPoint slideResearch highlights
► Stress exponent values are independent of the loading conditions in hardness test.
► Stress exponent of used alloys is 3.39–5.12 and agrees with pervious results.
► Elastic modulus of used alloys is varied by changing on β Sn matrix microstructure.
► Internal friction values of used alloys are affected by changing on β Sn matrix.
