Reheating Process

The grain growth kinetics of Q235 during reheating process was studied with Monte Carlo (MC) simulation. Heating process was performed at 1223K, 1273K, 1323K, 1373K, 1473K and 1523K for 10s, 20s, 40s, 80s, 120s, respectively. Samples were tested on Gleeble 1500 thermal simulation tester. The experimental results were analyzed regressively to obtain grain growth kinetics equation. The kinetics equation of Q235 was introduced to MC simulation to simulate the microstructure evolution and compute the average grain size at different step during heating process. MC simulation results showed the grain distribution under different time and the grain growth is in consistent with physical simulation. The simulation results also can help to set processing parameters during reheating of ingot.

In this paper, modeling, procedure and algorithm using Monte Carlo (MC) technology were investigated respectively to simulate grain size and microstructure . First, two different kinetic model were defined by both experimental and statistics method. Then the procedure and algorithm were worked out based on MC technology. Thirdly, the grain growth process in HAZ was simulated, which has great influence on grain growth in HAZ. The result of the simulation demonstrates the grain growth process dynamically. Good agreement between MC simulation results and the experimental results was obtained which can provide a reliable evidence for evaluating the welding craft and the weldability.

Weak Texture

ABSTRACTAluminum films 1pm in thickness are deposited by sputtering and by partially ionized beam (PIB) deposition. In the as-deposited condition, the sputtered film has a weak texture while the PIB film has a very strong {111} fiber texture. Annealing at temperature between 250°C and 400°C for 0.5 hr induces grain growth accompanied by texture evolution. These aluminum films are characterized by an {111} texture superimposed on a random grain distribution. When the {111} component dominates as in the PIB condition, little texture evolution accompanies grain growth at successively higher temperatures. When the {111} component is weak, the random component decreases at the expense of a strengthening {111}. Grain growth kinetics are similar for both cases.
