In this work, low volume reinforcement ex-situ Ti-B4C composites were produced using two different routes: conventional powder metallurgy (PM) and hot-pressing (HP). The effect of phases processing method on corrosion tribocorrosion behaviour studied. Composites processed by PM lost the typical passive Ti matrix, while HP presented similar to unreinforced Ti. Tribocorrosion tests showed that bo...

Aluminium (Al)/Aluminium alloy composites are emerging as very promising materials, especially in the fields of aerospace and automotive for their various attractive and technically demanding properties. Discontinuously reinforced aluminium metal matrix composites with reinforcements as nanoparticles of ceramics in general and carbon nanotubes in particular have emerged as the forerunner for a ...

As a ceramic material, AlN has very good thermophysical and mechanical properties. In addition, is an effective refining agent for Mg alloys because it lattice constant similar to that of Mg. Therefore, ideal reinforcement magnesium matrix composites (MMCs), attracting increasing attention. This review addresses the development preparation technologies AlN-reinforced composites. The mainstream ...

Automotive and aerospace industries are required to light materials which have high properties. This causes to reduce production cost and fuel consumption. One of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. These materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. Powder metal...
