Solid phase diffusion bonding of Ti2AlNb alloy and titanium matrix composites at low temperature
Cailiao gongcheng, 2021 The Ti2AlNb alloy and the titanium matrix composites can be joined by direct solid phase diffusion, but the high diffusion temperature causes the base metal to undergo a phase transition, even the joint properties were therefore deteriorated.

Diffusion welding of nickel-based superalloys [PDF]
, 2011 Ni based superalloys can be welded by diffusion bonding. Temperature, diffusion coefficient, activation energy and Boltzmann constant influence the quality of diffusion bonding, so obtaining the best condition for welding is considered.

Diffusion Bonding of Molybdenum
Journal of the Japan Welding Society, 1968 It is generally acknowledged that the ductile joint of molybdenum is difficult to make by fusion welding because of its embrittleness due to recrystallization and grain growth.The purpose of this investigation is to obtain a ductile joint of pure molybdenum without recrystallization and extreme deformation by diffusion or pressure bonding processes ...

Diffusion bonding of RAFM steels: Evolution of interfacial oxide layer with pressure and microstructure and mechanical property after post bonding heat treatment [PDF]
Journal of Mining and Metallurgy. Section B: MetallurgyThe effect of increasing the bonding pressure from 10 to 20 MPa (5 MPa interval) at 1050°C for 60 minutes on the diffusion bonded joint of reduced activation ferritic/martensitic (RAFM) steel was investigated. The results indicate that the quality of the

Diffusion bonding of gold [PDF]
Gold Bulletin, 1998 Gold has a low modulus and does not form an oxide skin when heated in the air. Added to this is its rapid self-diffusion characteristic and these three properties together make this metal suitable for joining gold to gold. This paper presents a summary of a practical diffusion-bonding method for making such joints.

Investigating effects from restricted diffusion in multi-component diffusion data [PDF]
, 2014 We have investigated model systems in which effects from non-Gaussian restricted diffusion could be separated from effects caused by multiple diffusion coefficients. We applied various models to analyze the experimental data.
