Magnesium is used as a degradable body implant material. Utilization of magnesium as a degradable implant is hampered because of the high degree of degradation of the physiological environment. Given the nature of magnesium biodegradation, one must know how to prevent or suppress the speed of the rate of biodegradation, so that it can be adjusted to the rate of bone healing process. Several studies have been performed to overcome these limitations, such as the equal-channel angular pressing (ECAP) procedure, which is used for grain refinement; this procedure can decrease the degradation rate and increase the mechanical properties of magnesium. We analyzed the mechanical properties of ECAP magnesium after immersion in DMEM solution using 10 ECAP magnesium samples each for the bending and ductility tests. The obtained values were used to analyze the mechanical properties on their respective tests. Time of immersion affected the bending and ductility values of ECAP and decreased both bending and ductility value of ECAP on immersion in DMEM physiologic liquid.
