A New Procedure for the Rapid Determination of Yield and Tensile Strength from Hardness Tests

  • Barrie S. Shabel
  • Robert F. Young


A new procedure for estimating the yield and tensile strengths of metallic alloys from hardness type measurements is described. The method has been successfully applied to alloys with different crystal structures and a wide range of strengths. The procedure is based on the calculation of modified Meyer hardness numbers from load and ball indentor penetration depth data. The computer-aided data acquisition and analysis includes corrections for machine deflection and elastic specimen recovery effects, providing a unifying framework for tests using a variety of loads and indentors. The method is also suitable for continuous load-depth data acquired in a single hardness test.
