Modern industrial development has put forward higher demands on the performance of metallic structural materials, especially in terms light weight, high strength and corrosion resistance. All these characteristics are particular importance transportation fields. As one most representative aluminum alloys have exhibited significant advantages weight. Most prominently featured specific aspect. Th...

Abstract Laser powder bed fusion (LPBF) is a metal additive manufacturing (AM) process for fabricating high-performance functional parts and tools in various metallic alloys, such as titanium, aluminium tool steels. One specific AM application conformal cooling channels (CCC) plastic injection moulding inserts to improve efficiency. This article reports the development of novel hybrid powder-wr...

A low cost and scalable powder-based method for producing nanoporous Ni is demonstrated, the only processing by-product water vapor. This achieved by creating a metal–matrix composite of NiO that then reduced under dilute hydrogen to create pure with nanocrystalline structure nanoscale porosity. The technique demonstrated in loose powder thin bulk compacts centimeter dimensions. These can withs...

Precipitation hardening, because it involves the hardening of the material over a prolonged time, is also called age hardening, or ageing. By the appropriate heat treatment of precipitation hardening, the strength or hardness of some heat-treatable aluminium alloys can be enhanced by the formation of nano-meter sized second-phase precipitated particles within the original phase matrix. The fine...

An ideal biomaterial is expected to exhibit properties such as a very high biocompatibility, that is, no adverse tissue response. Also, it must have a density as low as that of bone, high mechanical strength and fatigue resistance, low elastic modulus and good wear resistance. It is very difficult to combine all these properties in only one material. Some metals are used as biomaterials due to ...
