抄録

There is limited application of magnesium alloys as metal-forming products because of their poor plastic deformability at normal temperatures and their high production cost. To promote products manufactured by metal forming, rolling technologies enabling the production of thin sheets with suitable mechanical properties and surface qualities are required. To investigate the optimum rolling condition, hot-rolled AZ31 sheets were experimentally rolled by four-pass warm rolling in a total reduction range of 76 % with or without lubrication states in the temperature range from 293 K to 573 K. Rolling behaviors such as rolling force, grain structures and grain orientations were investigated. Mechanical properties such as tensile strength, elongation and r value were measured by tensile tests. Then, bending tests and conical cup tests are conducted for sheet forming tests. Finally, the effect of warm rolling conditions on their mechanical properties and sheet formability are discussed.
