Research on Properties of RE-7075 Al alloys Hot rolled

摘要：

　　The RE-7075 Al alloys hot rolled sheet was studied in this experiment.The microstructure,over-burning temperature,fracture surface and phase were analyzed by modern materials analytical instruments which include OM(optical microscope),DSC(differential scanning calorimetry),SEM(scanning electron microscope) and XRD(X-ray diffraction),respectively.The results show that there are needle-like or rod-like grains in the SL direction and the fibrous or streamlined grains in the LT direction of hot rolled sheets microstructure;The microstructure takes place the phenomenon of over-burning when rolling temperature beyond 480℃; These sheets manifest mainly brittle fracture under the tensile stress; The primary phase of microstructure contain α(Al),AlLa4,Al2Zn3,AlMgZnCuLa,LaMgZn,AlMg4Zn11.
