Strength of 316L Stainless Steel Single-Lap Joints Brazed with Ni-Based Metallic Glass Foils for Corrosive Environments

In brazing, the choice of base metal, brazing filler metal (BFM), and braze process conditions involves complex tradeoffs among cost, mechanical strength, corrosion resistance, others. this work, tradeoff between strength resistance 316L stainless steel joints brazed with a newer “very corrosion-resistant” Ni-Cr-P-Mo-Si BFM more established “corrosion-resistant” Ni-Cr-Si-B is quantitatively analyzed. Corrosion tests microstructural analyses were performed using common practices. Joint was evaluated by testing single-lap (SLJs) in tension following standardized procedures. However, conventional interpretations found to be inadequate for quantitative comparisons. Therefore, SLJ stress state analyzed detail complete interpretation developed. shown determined geometry, properties, microstructure. This analysis used explain occurrence different failure modes (fast fracture, peeling, failure) make suggestions improved methods conducting analyzing tensile tests. The provide significantly better moderate reduction strength.
