It has been established that the kinetic curves of adhesion (strength increase) are sigma type with displacement period second stage relative to first one. The this is determined by starting a marked metal flow over micro-protrusion contact sections and its passing on baton into harder material under kind stresses. Activation surface (corundum) occurs due handover deformation layer plastically ...

Blends of nanoscale fillers and polymers are of interest for a wide range of applications. Among these, block copolymer (BCP) nanocomposites are an interesting class of materials in which the block copolymer can guide the spatial location and periodic assembly of the additives. 4 This approach exploits differences between the chemical nature of the constituent blocks to direct the organization ...

Automobile manufacturers have recently focused their research on the concurrent improvement of fuel efficiency and stability. To implement lightweight body structures, joining dissimilar materials, such as advanced high-strength steel (AHSS) carbon fiber-reinforced polymer (CFRP), is most important, whereas fusion welding, which conventional welding process, inapplicable owing to difference in ...
