Creep of Sn-9Zn as Measured by a Bending Test Method

A bending creep setup was introduced and its feasibility to evaluate creep behavior of materials was experimentally verified on pure Sn.Thereby,the creep of eutectic Sn-9Zn was studied.It was identified that high and low stress regimes exist in the creep of Sn-9Zn,and in both stress regimes,the data obtained well fit the modified equation of Norton power law.Parameters n and Q in the modified Norton equation obtained are very closed to those reported by other researchers by means of conventional tensile creep tests.The mechanisms governing the creep deformation of Sn-9Zn in both stress regimes were also discussed.
