MASS MANUFACTURING METHOD OF MATERIALS HAVING EXCELLENT LOW TEMPERATURE SUPER-PLATICITY

摘要

A method for massively manufacturing material having excellent low temperature super-plasticity is provided to reduce processing cost of material by producing the material having the excellent super plasticity at low temperature. A method for massively manufacturing material having excellent low temperature super-plasticity comprises: a step of heating material; a step of manufacturing board material by rolling the heated material with a roll which is heated; and a step of heat-treating the rolled board material at the temperature of 100-400°C for 10 minutes~10 hours. The temperature for heating the material and the roll is 100~400°C. The rate of the rotation speed of two rolls facing in differential speed rolling is 1.5:1~5:1.
