EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

The expanding transport and traffic sector and the associated negative impact on the environment pose ever greater challenges for the automotive industry. Materials need to become lighter and more sustainable without sacrificing performance. In order to meet the growing demands for lightweight materials that offer not only high strength but also sufficient forming performance, a big step...

A single addition of the rare earth elements neodymium and yttrium have been made to mischmetal-free magnesium alloys Mg-3Nd and Mg-3Y. Both alloys were prepared by the means of powder metallurgy. A modern spark plasma sintering technique was used to effectively produced fully dense samples from gas-atomized powders. Two sintering temperatures – 450 °C and 550 °C and two external loads – 100...

Open-cell metal foams, among them aluminum and copper foams, are used as catalyst supports, heat storage material supports, or filters due to combined properties such as high thermal and electrical conductivity and high liquid/gas permeability. A high specific surface area plays an important role in this application. This work presents a novel method for the production of hierarchically porous...

Aluminum alloys with addition of Fe and Si are commonly used as packaging foil stock materials. Homogenization is an important initial technological step, which significantly affects behavior of the alloys during further processing and also the quality of the finished product. The main point of homogenization is to suppress non-uniformity of solutes distributions formed during casting due to...

Annealing deformed metals usually leads to reduced mechanical strength. However, for nanostructured and ultra-fine grained (UFG) materials, the opposite effect was observed after low-temperature annealing (TH<0.35). In case of pure metals, this phenomenon can be associated e.g. to the annihilation of the mobile dislocations and changes in the character of grain boundaries. It is well known...

Titanium and its alloys are widely used in applications where high strength and light weight are required. Due to their biocompatibility, Ti alloys are also used in numerous medical applications like dental implant or bones prosthesis. However, Ti alloys suffer from poor tribological properties that limit their use when wear is experienced. Thermochemical treatment like nitriding or...
