Stress‐strain curves were obtained in flexure and in tension on single crystals of MgO. A decrease in iron content and high‐temperature heating and rapid cooling caused a decrease in strength and increase in ductility. Heat‐treatment of previously deformed specimens increased their strength. The slip band structures resulting from deformation were brought out by chemical etching, and their significant features are discussed.
