Refining as-solidified grains of metals to the ultrafine and even nanometer scale by …

A novel thermo-mechanical process was adopted to obtain deformation-induced ultrafine-
grained ferrite in the surface layers of a microalloyed steel plate. The new process referred …

In this study, an in situ β–Ti–Nb composites reinforced with TiC particles with an ultrafine
grain size were fabricated using a powder metallurgical (PM) method. The microstructures …

The good combination of mechanical and tribological properties for self-lubricating materials
is crucial. In this work, novel self-lubricating Fe-16.4 Mn-4.8 Ni-9.9 Al-xC (wt%) steels …
