It is well established that microstructure is an important factor in determining the corrosion behaviour of aluminium alloys. (W 133) (1)

Corrosion behaviour = Conduta corrosiva

Full size endurance testing is required to give a more complete understanding of the corrosion fatigue behaviour of girth welds in candidate stainless steels for riser applications (W 103) (2)

Fatigue behaviour = Conduta fatigante

For this paper, there was a need to generate equivalent data looking at notch acuity for SENT specimens, both for ductile and brittle behaviour. (W 17) (3)

Brittle behaviour = Conduta frágil

The three techniques that are currently commonly used to join composite materials to metals are adhesive bonding, mechanical fastening and a combination of the two. (W 241) (1)

Adhesive bonding = Colagem adesiva

Titanium is the easiest of all common engineering materials to join by diffusion bonding, due to its ability to dissolve its own oxide at bonding temperatures. (W 545) (2)

Diffusion bonding = Colagem por difusão

Of the numerous fusion bonding techniques available, three in particular have been the subject of many research studies as they are considered most suitable for industrial applications; induction, resistive implant and ultrasonic. (W 20) (3)

Fusion bonding = Colagem por fusão

High angular misorientation is observed between planar zones and neighbouring dendritic regions. Elongated grains, perpendicular to the fusion boundary, indicated grain growth towards the centre of the weld pool, during solidification. (W 18) (1)

Fusion boundary = Limite de fusão

In almost all fractured specimens, a unique cleavage origin at a grain boundary could be traced, confirming the validity of the weakest-link assumption. (W 300) (2)

Grain boundary = Borda do grão

Finite element analyses have been carried out to obtain static elastic stress intensity factors for the initial and arrested crack under constant load and constant displacement boundary conditions. (W 382) (3)

Displacement boundary = Limite de deslocamento
