โœฆ Synopsis

Fractographic examination of creep crack growth behaviour in a mechanically alloyed material, IN-9021-T452, reveals unexpected morphologies. The material exhibits superplastic deformation oflocal fibres surrounding intergranular fracture. High strain rates promote 100% superplastic fibre formation. The fractographic mechanisms reveal a balance between strength and ductility.

The effect of a rapid pre-strain on the cavitation behaviour of commercially processed superplastic (SP) aluminium alloy 5083 sheet material deformed in uniaxial tension has been compared with that for deformation under constant strain rate conditions. It was observed for the two test conditions, th
