摘要：

We study by Monte Carlo simulation the influence of vacancies on the growth of antiphase domains after a quench of a BCC binary alloy. We find a power-law regime R(t)similar to t(x) with x depending on temperature and larger than the Allen-Cahn value 0.5. We have verified the scaling of the structure factor and performed a finite size analysis of the excess energy evolution and vacancy diffusion.
