Abstract

An attempt has been made to model strain hardening parameters for sintered iron and iron-0.4% carbon steel preforms that are subjected to cold upsetting. The aspect ratios and lubricants are also considered as variables apart from the compositions. The 2 power 3 factorial design has been considered to design the experiment and subsequently Yate’s algorithm is utilized to construct the model. The model has further been refined using analysis of variance. The final model adequacy is determined through correlation coefficient which is predicted to follow near unity. Thus the mathematical model can be utilized to predict strain hardening parameters such as strength coefficient, K, and strain hardening exponent, n, subsequently to design the process parameters to inculcate the required strain hardening characteristics within the range of process parameters specifications that are considered in the present investigation.
