Effect of Anisotropy on the Manufacturing Process of Mg-Zn-Zr Alloy Connecting Rod

In this study, a new alloy material Mg-Zn-Zr (ZK60) was designed for the connecting rod. It found that blanks sampled along vertical direction of an extruded bar crack during roll forging process. The microstructure and precipitates were observed analyzed using optical microscope (OM), scanning electron (SEM) x-ray diffraction (XRD). result showed Zn, Zr, MnZn2 elongated extrusion direction. mechanical anisotropy investigated by testing properties specimens sampling from different angles. Hot deformation behavior further studied Gleeble 3500 thermal-mechanical simulator. tensile yield strengths highest direction, reaching 347 MPa 301 MPa, respectively. resistance also higher in than Fracture mechanisms sample directions discussed. ZK60 more susceptible to failure if parallel bands segregation area precipitates.
