Abstract:The conventional hot rolling of AM50 alloy at different roll temperatures and speeds was performed to investigate the effects of finish-rolling conditions on the mechanical properties and texture of rolled sheet. The better combination between strength (ultimate tensile strength: 295 MPa; yield strength: 224 MPa) and ductility (22.9%) can be obtained for the AM50 sheet rolled at the roll temperature of 200 °C with the roll speed of 5 m/min. The yield stress depends strongly on roll temperature, while the texture intensity in rolled sheets is more sensitive to roll speed during hot rolling. Increasing rolling temperature or roll speed can improve the mechanical anisotropy of AM50 rolled sheets.
Key words: AM50 alloy; hot rolling; mechanical anisotropy; texture
