Strain hardening analysis and modelling of its parameters for sintered Al and Al-1%C preforms during cold upsetting
Source abstract
Abstract
An attempt has been made to model strain hardening parameters for sintered aluminium and aluminium-1%carbon preforms that are subjected to cold upsetting. In addition to compositions, the sintering temperatures and lubricants are considered as variables. The 2k 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 and model adequacy is determined through correlation coefficient which is predicted to follow near unity. Thus, this 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.
