Abstract
According to the state-variable annealing models (Sellars [1]) for the annealing of hot and cold worked C-Mn steel, simplified mathematical models for non-isothermal heating of brass were derived to calculate the grain size and mechanical properties, i.e. hardness, after a short annealing time in an industry furnace, e.g. strip floatation furnace. In contrary to Neidel’s models [2] using hardness vs. reference-temperature curve for calculation of non-isothermal heating, these models calculate the results directly by using finite difference scheme. Based on isothermal annealing at various times and temperatures, recrystallization and grain growth kinetics of 70:30 cartridge brass at two degrees of cold work were determined. The determination of parameters bases on mathematical fit to the isothermal annealing data. These parameters are then used in the mathematical models for non-isothermal heating. The results show that calculated data correspond well with experimental data.
