Grain Size Evolution
QForm Grain Size Evolution is a special module for simulation of microstructure evolution during thermomechanical processing of steels, nickel-, titanium-, aluminum-based and other alloys
-
All-in-One microstructure simulation
  • Recrystallization analysis

  • Control of grain growth and coarsening of structure

  • Evaluation of grain grade according to international standards

  • Determination of microstructure evolution type

  • Calculation of the process chain heating-deformation-cooling

  • Advanced material database

The calculation takes into account the influence of temperature on the coefficients of the model, as well as the cyclic recrystallization. The module can perform end-to-end calculations of microstructure evolution in the process chain with inheritance of calculation results and works for both 2D and 3D problems.

Thermomechanical processing optimization

This module enables users to analyze and fine-tune thermomechanical processing parameters, including:

Deformation Mode Optimization – Adjust strain conditions to achieve the desired microstructure and mechanical properties

Thermal Cycle Planning – Select optimal temperatures, dwell times, and heating durations to prevent grain growth and microstructure coarsening


Look deep into process

The module calculates a comprehensive set of parameters related to recrystallization and microstructure evolution, including:

  • Volume fraction and average grain size for dynamic, static, and metadynamic recrystallization

  • Total recrystallized volume and ASTM grain number

  • Microstructure evolution type and retained strain

  • Critical deformation and initial grain size before each cycle

  • Number of recrystallization cycles (if cyclic mode is enabled)

  • Reference fields such as deformation time, average temperature, strain rate, dwell time, and grain growth duration

These results provide deep insight into material behavior during thermomechanical processing.
