Abstract
The underlying assumptions involved in the use of a variety of tempering parameters have been examined and compared critically with experimental results for a plain carbon steel It is found that the assumptions and experimental results are in conflict for any simple parameter but because of the insensitivity of their mathematical forms to changes in tempering time certain parameters are capable of adequate representation of the hardness changes which occur during tempering The widely used HollomonJaffe parameter is found to be the most successful in covering a wide range of hardness changes
