Open AccessThe finding of anisotropic compatibility of grain boundaries in a directionally solidified superalloy
The anisotropic compatibility of grain boundaries (GBs) is found in a directionally solidified superalloy, when loading is aligned with (L sample) or transverse (T sample) to the grain growth direction. The gr...

Open AccessThe hot deformation behaviour of laser powder bed fusion deposited Al–Si–Cu alloy processed by high-pressure torsion
The tensile properties of an ultrafine-grained Al–9%Si–3%Cu alloy deposited by the laser powder bed fusion process have been investigated in this work. The additively manufactured (AM) alloy was subjected to h...

Open AccessMicrostructural and hardness evolution of additively manufactured Al–Si–Cu alloy processed by high-pressure torsion
Nanostructured Al-9%Si-3%Cu alloy was achieved by direct metal laser sintering (DMLS) and then processed using high-pressure torsion (HPT) processing, which resulted in considerable grain refinement down to 60...

An investigation into the effect of substrate on the load-bearing capacity of thin hard coatings
TiN and diamond-like carbon (DLC) coatings were deposited on Ti substrates with and without processing by high-pressure torsion (HPT). The HPT processing refined the grain size of titanium from the coarse-grai...

The corrosion behaviour of commercial purity titanium processed by high-pressure torsion
Commercial purity (CP) titanium was processed by high-pressure torsion (HPT) under an applied pressure of 6.0 GPa for different numbers of torsional revolutions and then exposed to a 3.5 % NaCl solution for op...

Tribology testing of ultrafine-grained Ti processed by high-pressure torsion with subsequent coating
A grade 2 pure Ti was processed by high-pressure torsion (HPT) under 3.0 GPa for 10 revolutions to achieve an improved strength. Wear tests revealed that HPT only slightly improved the wear resistance of pure ...

Tribological properties of ultrafine-grained materials processed by severe plastic deformation
Processing by severe plastic deformation (SPD) has been developed extensively over the last two decades in order to produce ultrafine-grained (UFG) materials having submicrometre or nanometre grain sizes. An i...

Wear behavior of an aluminum alloy processed by equal-channel angular pressing
Wear tests were conducted on an aluminum Al-1050 alloy after processing by equal-channel angular pressing (ECAP). The results show that the coefficient of friction remains unchanged after processing by ECAP, b...
