Hi Tamara Just some references: Rawal/Murti Some Observations on Superplasticity in the Sn-Pb Eutectic 1972 Melton/Langdon Anisotropy during superplastic deformation of the Sn-Pb eutectic alloy 1975 Hariuchi On the effective stress dependence of steady state creep rate in SN-Pb eutectic 1974 Mohammed/Langdon Creep behaviour in the superplastic Pb-62Sn 1975 eutectic Knecht/Fox Constitutive relation and creep fatigue life model for eutectic tin lead solder 1990 Solomon Creep,strainrate sensitivity and low cycle fatigue of 60/40 solder 1986 Darvaux Constitutive relations for tin-based solder joints 1992 And please don't get mad if I add some references from our lab: L.Weber Creep fatigue behaviour of eutectic Sn62Pb36Ag2 solder 1997 Grossmann Mechanical Properties of Sn62Pb36Ag2 ( German ) 1998 Properties of thin layers of Sn62Pb36Ag2 1995 Metallurgical considerations for accelerated testing of electronic equippment 1997 Lifetime assessment of soft solder joints on the base of the metallurgical behaviour of Sn62Pb36Ag2 1997 The deformation behaviour of Sn62Pb36Ag2 and its implications on the design of thermal cycling tests for electronic assemblies 1999 Sorry that I couldn't resist to show what we did.
