Mathematical Model of Box-Behnken Design for Predicting Mechanical Properties of Heat Treatment of Inconel 738 Through the Use

2024-11-04T09:19:36+07:00

This research studied the application of Box – Behnken Design for mathematical model for predicting mechanical properties on the Inconel 738 through the use. The three main factors were studied: Solution temperature (X₁), Aging temperature (X₂) and Aging time (X₃). The resulting materials were examined using Box - Behnken experimental design to determine the resulting material hardness test. The experimental results show that using a full quadratic model with the proposed mathematical model. The most appropriate parameter for highest hardness is solution temperature 930 ^oC Aging temperature 600 ^oC and Aging time 20 hr. It can be concluded that the solution temperature, aging temperature and aging time have an influence on the hardness at statistically significant value of 0.05. The hardness of the specimen was highest with the amount of titanium carbide. The results of this research can be used as data for the heat treatment processing of Inconel 738.
