The flow stress in tensile and compressive deformation has been determined in cast Mg, for a wide range of grain sizes between 36 μm and 1.5 mm. The grain size was varied by alloying Mg with small amounts of Zr. It was found that the 0.2% offset flow stress, σy, (MPa), varies with the grain size, d (m), as σy = 17.7 + 0.25 d-1/2 in tension, while σy, = -2.3 + 0.39 d-1/2 in compression. Possible reasons for the difference between tension and compression are discussed.
