چکیده
In this paper, we study the strength and fracture mechanism of cast magnesium alloy Mg-Zn-Ca (1.0 % Zn, 0.2 Ca) for medical applications after equal-channel angular pressing (ECAP) in comparison with initial condition (after homogenization annealing). Mechanical tests included tensile torsion samples a diameter 3 mm impact V-shaped stress raiser. The microrelief all fractures was studied Phenom ProX G6 scanning electron microscope (SEM). results testing showed that ECAP increased by factor 1.5 –1.8, elongation 2.6. torsional 1.1–1.3, relative shear decreased 1.3 as compared annealing. contrast to static loads, Mg-Zn-Са is poorly resisting one-time loads. Analysis allows us conclude more promising manufacture products experience loads during operation,

Re-strengthening in AA6063 Alloy During Equal Channel Angular Pressing
Equal channel angular pressing (ECAP) is carried out using two different configurations for the exit channel of the ECAP die, i.e., relieved and choked, with angles of 0.2 °. It is found that using a die with relieved exit channel, the sample was extruded for 6 passes with no surface cracks and an average cell size of 727 nm and a fraction of high angle grain boundaries of 54 % were achieved. M...
متن کاملCharacteristics of Cavitation in a Superplastic Magnesium Az31 Alloy Processed by Equal- Channel Angular Pressing
Experiments were conducted on a magnesium AZ31 alloy to evaluate the role of cavitation in high temperature superplasticity. Samples were processed by equal-channel angular pressing (ECAP) and then pulled to failure in tension at a temperature of 623K. Similar tests were also conducted on the as-received alloy. The results show the development of significant internal cavitation in this alloy wh...

Equal-channel angular pressing provides an opportunity for refining the grain structure and introducing superplastic properties in magnesium alloys. This report describes the use of this processing technique with a ZK10 (Mg–1.0 wt.% Zn–0.26 wt.% Zr) alloy. The grain structure was successfully refined from ∼12.9 to ∼5.2 m after 4 passes and superplastic elongations were observed when testing at ...
