A theory of rockwell ball hardness

  • 149 Accesses

  • 1 Citations


A theoretical analysis of the Rockwell method of ball hardness measurements is made. A general expression for Rockwell ball hardness numbers in terms of the Meyer constantsn andb is given. It is shown that the theoretical results are in agreement with experimental results. The conversion of Meyer and Brinell hardness numbers to Rockwell hardness numbers is discussed.
