Statistical Analysis Of Diffusion Bonding Nickel Using Brass Interlayers
… goal of this project is a statistical study of diffusion bonding of commercially pure Ni with a brass interlayer. Four factors were investigated; time, temperature, surface finish, and foil thickness. A Box-Behnken design was selected to analyze the system for composition and strength of the …

Investigation of mechanical behavior and microstructural characteristics of diffusion bonded 316H stainless steel for compact heat exchanger applications
… heat-transfer capacity at elevated temperatures. Diffusion bonding has been an effective technique for the fabrication of joints in heat exchanger applications. However, the structural integrity of the diffusion bonded joints is critical. Type 316H austenitic stainless steel has been a candidate …

The Influence of Alloying Additions on Diffusion and Strengthening of Magnesium
… approach must be taken where thermodynamics and diffusion kinetic parameters form the basis of alloy design, process development, and properties-driven applications. The objective of this research effort is twofold: first, to codify the relationship between diffusion behavior, crystal structure, …
