The current work focuses on study of input parameters of induction hardening process of micro-alloyed steel roller shaft of an Undercarriage. Regression relation is generated for hardness using Response Surface Methodology (RSM) by using Design Expert Software as a tool for optimization. Further, the micro structure of selected shafts was analyzed.

The optimization of process parameters and catalyst compositions for the CO2 oxidative coupling of methane (CO2-OCM) reaction over CaO–MnO/CeO2 catalyst was developed using Response Surface Methodology (RSM). The relationship between the responses, i.e. CH4 conversion, C2 hydrocarbons selectivity or yield, with four independent variables, i.e. CO2/CH4 ratio, reactor temperature, wt.% CaO and wt.% MnO in the catalyst, were presented as empirical mathematical models. The maximum C2 hydrocarbons selectivity and yields of 82.62% and 3.93%, respectively, were achieved by the individual-response optimization at the corresponding optimal process parameters and catalyst compositions. However, the CH4 conversion was a saddle function and did …
