Temperature-Dependent Debonding Resistance of 316 Stainless Steel, Inconel 625, and Ti-6AL-4V Alloys

Abstract

This study investigates the temperature-dependent debonding properties of 316 Stainless Steel (SS), Inconel 625, and Ti-6Al-4V alloys in additive manufacturing using the finite element method. The analysis reveals notable relations between in mechanical properties and debonding resistance among these materials. Inconel 625 demonstrates superior performance at elevated temperatures, while SS and Ti-6Al-4V alloys show earlier degradation. Regarding debonding resistance, Inconel 625 performs comparably to SS and Ti-6Al-4V alloys, with Ti-6Al-4V exhibiting consistent resistance below 500 °C. SS, however, experiences a rapid loss of debonding resistance at lower temperatures. These findings provide valuable insights for material selection and design optimization in additive manufacturing. Further research can expand our understanding of these materials' behavior under different temperature regimes using the finite element method, enhancing their application potential.
