Die Härtescala in absolutem Maasse

Abstract: D i e HCirtescala $1.1 absolutern Maasee; V O N 3 . A u e r b a c h .Einleitung.Einer grossen Anzahl neuerer Vorschlilge zum Trotz hat sich bis auf den heutigen Tag die bekannte Mohs'sche Hartescala als die einzige erhalten, welche in weiteren Kreisen als Grundlage fur die Angabe von Hartewerthen benutzt wird. Dieves conservative Vsrhalten der Physiker, Mineralogen und Techniker ist im Wesentlichen der Ausfluss der richtigen Nrkenntniss , dass eine wissenschaftliche Hartescala such auf die Methoden von Seebeck… Show more

“…Since cracks opened under tensile stress, he concluded that the surface condition might also have influenced crack nucleation. Extending the in situ measurements to ductile transparent solids such as rock salt, calcite, fluorite and others, Auerbach (1892Auerbach ( , 1896 proposed that hardness be taken as Hertz's pressure at the onset of plastic flow indicated by an almost constant contact pressure. When applying to (opaque) metals, the area of contact was determined employing a blackened indenter (Auerbach, 1900).…”

“…This was realised in the early 1890s by Auerbach who published a number of papers on the problem of ‘absolute hardness’. 26,198,199 This issue was helpfully reviewed by Mahin and Foss in 1939. 200 Honda 132 suggested that intrinsic hardness be defined as ‘the intensity of maximum pressure which just produces yielding’.…”
