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 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: Metallurgy
The 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

Effect of Post-Weld Heat Treatment on the Solid-State Diffusion Bonding of 6061 Aluminum Alloy

Applied Sciences, 2021
The precipitation-hardenable aluminum alloy 6061 (AA 6061) is favored for aerospace components and automotive parts. However, the tenacious oxide layer on the surface greatly limits the quality and applicability of joining AA 6061.

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.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
