“…Magnesium alloys typically exhibit brittle fracture, characterised by cleavage or quasi-cleavage. 44 In the SEM images, it is evident that all processed biomedical alloys display small cleavage planes and tearing edges, indicating quasi-cleavage fracture, which differs from the brittle fracture observed in the as-cast Mg. 45 Additionally, the fracture surfaces of the alloys show the presence of dimples, which may result from the combination of micro-voids ahead of the cracks. The distinct brittle fracture behaviour observed in the pure Mg and the processed alloys in this study can be attributed to several factors: grain refinement achieved through CECAP-FE, the formation of precipitates during the process, and the distribution of alloying elements and second phase particles within the alloys, as evidenced in the backscattered images of the fracture surfaces shown in Figure 5.…”

In this study, cyclic extrusion compression angular pressing-forward extrusion was employed to develop binary magnesium-based multiphase alloys, and subsequently analysed the microstructural, mechanical and corrosional properties of the resulting samples. The findings demonstrate that the inclusion of alloying elements in the multiphase alloys significantly enhances their microstructural, mechanical and corrosional properties. Compared to pure Mg samples fabricated using the same method, the multiphase alloys produced by this technique exhibit finer grain structures. Mechanical analysis indicates that these multiphase alloys possess higher yield and ultimate strength compared to pure magnesium. Corrosion testing reveals that all produced alloys outperform pure magnesium in various aspects. Particularly, Mg–1Zn and Mg–1Mn alloys exhibit exceptional corrosion resistance in immersion, mass loss and polarisation tests.

In the current study, a novel severe plastic deformation (SPD) technique entitled cyclic extrusion channel angular pressing (CECAP) is proposed appropriate for producing ultrafine grained cylindrical material. In this new method, cyclic extrusion compression (CEC) and equal channel angular pressing (ECAP) processes are combined which solves drawbacks of both processes.Advantageous of the new process may be considered in two views of points of processing and properties. This new process increases the hydrostatic compressive stress of ECAP as well as shear to the total strain of CEC. Also, CECAP solves needing back pressure problem of CEC process which is an important feature of the new process. The process treated an AZ91 alloy and remarkable grain refinement and significant improvement in strength, ductility and hardness were achieved because of higher hydrostatic compressive stresses.
