Statistical modeling of microstructure evolution in a Ti-6Al-4V alloy during isothermal compression
نویسندگان
چکیده
A statistical continuum model is developed in the present study which uses microstructural information for a two-phase Ti-6Al-4V alloy to simulate microstructure evolution during hot isothermal compression. Current models of prediction often use finite element methods. However, here does not rely onfinite methods and thus can be performed much faster with less computational resources without sacrificing accuracy. This approach two-point statistics describe related phase distribution, grain size phase/grain morphology. formulation further utilizes macroscopic strain-rate tensor predict deformation. The deformation then used calculate resulting deformed microstructure. Finally, simulated compared that experimentally obtained from scanning electron micrograph backscatter mode i.e. SEM (BSE) images microstructures.

Microstructural Evaluation of Ti-6AL-4V Alloy during Hot Deformation
Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...
