Abstract
The paper presents constitutive equations for the large deformations of a near-alpha titanium alloy in forging. The equations model anisothermal behaviour and provide a description of microstructural evolution due to dynamic recrystallisation. The stress-strain behaviour and the microstructural evolution, are well characterised by the equations over the temperature range 400–1100°C, and strain rate range 0-005-10-0s−1. A micro-mechanical model for void nucleation and growth under generally compressive stress states has been developed. The material model established has been implemented into finite element software and used to simulate the forging of cylindrical specimen tests. The model is also used to predict strain induced porosity measured in experimental compression tests. Good comparisons between predictions and experimentally determined results are achieved.
