Abstract

Abstract

Material scientists have always faced a significant obstacle in the process of joining materials that are distinct from one another. The main aim of this research is to join stainless steel with alumina under pressure. The ceramic and stainless steel SS 304 were joined in this work by brazing with a torch and furnace. The study focused on a ceramic-to-stainless steel joint: a stainless steel 30 mm stripe that was brazed to alumina using the same brazing alloy and alumina to themselves. The joints were evaluated using numerical analysis, and the module was run by Ansys 18.2 in Solidworks 2017. The tensile strength of the experimental work reached 62 MPa during slow cooling with pressurized air at the furnace, as shown by the numerical analysis result. This is lower than the fracture of the ceramic material alumina.The Tensile Stress at 65.3MPa in the numerical analysis corresponds nearly exactly to the experimental work.
