Hot compression deformation behavior of TC4 titanium alloy was studied on Thermecmaster-Z simulator in the temperature range 850 degrees C similar to 1150 degrees Cand strain rate range 0.5 s(-1)similar to 30s(-1). The results show that deformation temperature and strain rate both have significant influence on the flow stress. The flow stress decreases with the increase of deformation temperature, while increases with the increase of strain rate. The deformation mechanism of TC4 alloy exhibit dynamic recovery feature in high temperature. However, in lower temperature, dynamic recrystallization and grain boundary slip behavior may take place. Deformation activation energy values are 863.46 kJ/mol in (alpha + beta) phase region, and 209.80 kJ/mol in beta region respectively. Constitutive equations of TC4 alloy described by Zener-Hollomon parameter were formulated. Therefore, a scientific basis is provided for the reasonable choice of thermal parameters of TC4 titanium alloy.

A series of creep experiments are carried out for MDYB-3 PMMA under different stresses at the room temperature.The whole process from the crazing initiation and growth to specimen's fracture under creep is researched,finding out that the crazing in PMMA present the alternating distribution of sparse and dense,which is perpendicular to the load.Based on the experimental data and analysis,a relationship between stress and the time of the crazing initiation is given,which quantifies the crazing initiation time shortened non-linear as the stress increases.And a model is built to describe the crazing damage density with stress and time for MDYB-3 PMMA using of non-linear fitting based on hyperbolic function.
