Abstract
BY means of multiple-beam interference methods we are carrying out a systematic examination of the distortions produced on various surfaces by standard diamond hardness indenters, including respectively (1) Vickers pyramid, (2) Rockwell cone, (3) Knoop pyramid, (4) double-cone indenter (devised by P. Grodzinski), using micro- and macro-indenters. Owing to their widespread use, we report here first some preliminary observations made with a Vickers diamond pyramid and with a Rockwell cone, since these are of particular interest.
