Abstract: The influence of static mechanisms on fatigue crack propagation in Ti and Ti-V microalloyed steels is considered. Small inclusions originate void nucleation. In contrast, TiN coarse particles ...

Abstract: The photocatalytic features of TiO2 doped with ferric oxides or mixed with activated carbon (AC-TiO2) are compared with those of the unmodified Degussa P-25 TiO2. These new catalysts show ...

Abstract: In the present work, it is shown that friction can be used to deposit diamond in a substrate of copper. Here it was found through electronic scan microscopy that a composite material film ...
