LOW TEMPERATURE HARDNESS AND FLOW STRESS RELATIONSHIPS OF METALS.
Abstract
An empirical relationship between hardness and flow stress at low temperature is formulated, based upon Tabor's analysis (The Hardness of Metals, Oxford University Press, Amen House, London, 1951) of the Vickers hardness test and the authors' work on flow stresses in the tension test. As this relationship appears to be in agreement with recent dislocation theory, it may also be considered a better first approximation than previously proposed hardness and flow stress temperature dependent functions. Tests were conducted on several alloy steels, Cu, Al, Fe, and Ti, over a range of test temperatures from 200 to -196 C. (Author)
