Influence of different parameters on compression strength of foam steel produced by slip reaction foam sintering

Abstract

In this study, a 24 factorial design was used to investigate the magnitude effects of sintering temperature, mill scale, carbon content and starch additions on compression strength of produced foam steel. The design was based on experimental results of compression test of steel foam with additions of mill scale up to 20%, carbon up to 0.5%, sintering temperatures from 1000 to 1200°C with starch (from 3 to 12%). MatLab was used to carry out the required calculations. Regression models were used to deduce a mathematical formulation to predict the influence of different parameters on compression strength of foam steel.The results showed that mill scale addition has the highest positive effect while the interaction combination between starch with carbon has the highest negative effect on compression strength. The results of the driven model were found to be in good agreement with the experiments and publishing work.
