Abstract: This paper discusses single and multiple characteristics optimisation of induction hardened AISI 1040 steel in rolled condition. Face centred central composite design was used for experimentation. Response surface methodology was used for modelling the responses. Desirability function in conjunction with RSM was used for the optimisation of responses. The results are validated from the existing knowledge of physical metallurgy in general. The solutions, thus developed using different practical and industrial situations, can easily be utilised for tailor-made production of the steel of desired hardness, total case depth and mean effective case depth.
Keywords: induction hardening; response surface methodology; RSM; desirability function; steel; modelling; case depth.
