The surface sealing is related to the ion bombardment, which produced a high mobility of surface atoms and consequent enhanced diffusion as well as sputtering and condensation on

The healing process was evaluated using a dermal ulcer model and the results showed a good tissue repair resembling a physiologic process.. The overall results presented here lead

• Solid inclusions grown on seed crystal interface are responsible for the nucleation of dislocation bundles appearing in +X- and –X- growth sectors formed around the Z-axis. •

ing temperatures and holding times. In these cases, the ad- hesion strength between the diamond wafer and the tung- sten carbide substrate was probably higher than the intrin-

Titanium alloy Ti6AL4V ASTM F136 (Ti) and stainless steel AISI 316L (SS) plates were cut into small rectangular samples (20 mm, 10 mm, 1 mm). The plates were metallographically

A good consistency between ER change values is observed in different experiments: thermal martensitic transformation, stress induced martensitic transformation and stress

According to the case analyzed here, which involves the weld repair of a 1¼Cr½Mo ferrite-pearlite steel steam pipe operating for 20 years at 480 °C, in service weld repair leads

For series A steel intercritically annealed at 785 °C with starting microstructure of ferrite plus pearlite, austenite nucleated at the pearlite colonies, so the holding time of
