Vickers microindentation tests were carried out on a bulk MgB 2 superconductor with loads ranging from 300 to 1500 mN at room temperature. The load-penetration depth curves were analyzed by a power law of the form P = Ch m. The β-material for bulk MgB 2 is determined. © Springer Science+Business Media, LLC 2010.
