Effect of Processing Routes on AZ31 Alloy Processed By Severe Plastic Deformation

Effect of ECAE Die Angle on Microstructure Mechanical Properties and Corrosion Behavior of AZ80/91 Magnesium Alloys

“…The intensity of the peak in the ECAP processed specimens at 598 K is lower than that of the as-received specimen. Also, it can be seen that there exists great difference on the magnitude of the peak intensity of ECAP processed specimen at 598 K for two and four passes this is mainly due to induced plastic strain during ECAP similar results has been observed by Avvari et al [24][25][26][27][28].…”

A Comprehensive Review on the Influence of Equal Channel Angular Pressing Parameters on Magnesium Alloys

“…As observed in route B C , the alloy exhibits a maximum deformation due to the grain refinement compared to route A and C. Fig. 10 shows the microstructure of route A, C and B C after 2 passes at a temperature of 498 K. Among these three different routes applied, the most conventional reported to achieve a homogeneous microstructure for most alloys is route B C [75]. According to Komura et al [76] the optimum super plastic ductility is achieved by route B C due to the most rapid generation of equiaxed grains with the high angle of grain boundaries.…”

“…The paper aimed to introduce a new preliminary step rolling before ECAP process to obtain better mechanical properties and smaller grain size of the material after ECAP compared to a material processed by ECAP only. In 2014, a research done by Avvari et al [72] studied the influence of ECAP processing route on the microstructure and mechanical properties of AZ31 after 2 passes at temperature 498K. All these research findings are summarized in Table 3.…”

“…Avvari and his co-worker [72] investigated on the effect of processing routes on AZ31 alloy by severe plastic deformation. In this research, 3 different routes have been selected to access its efficiency.…”

“…Tensile strength is conducted according to certain standard depending on the condition of the samples. For example, in a research done by Avvari et al [72], the samples were rodshaped, hence the tensile test were done by following standard ASTM E-8 which the gauged length and diameter of the specimen to be 15 mm and 5 mm respectively.…”
