The alloy is held for 30-120 minutes before the warm rolling. The warm rolling is carried out at a rolling speed of 2-20 m/min. and a draft percentage per pass of 2-18 %. The obtained Al-Li alloy has finer grans. The process exhibits excellent super-plasticity at a strain speed of 20-100 times higher than that of conventional process.
