Special Issue Information

Dear Colleagues,

High-strength materials are now widespread, from medical implants to products used in aerospace, the automotive industry or marine environments. Such a wide range of applications entails the use of both steels and non-ferrous alloys, as well as unconventional materials, including ceramics, composites, multilayer alloys, etc. The main advantages of these groups of materials are their attractive structural, mechanical, thermal properties, which, in its turn, means the use of such technologies such as high-temperature thermo-mechanical processing, powder metallurgy processing, plasma or laser coating, additive manufacturing technologies, and so on. On the other hand, it is necessary to ensure the high efficiency and quality of production processes, which is not an easy task because these materials are considered to be hard to cut.

The main aims and scopes of this Special Issue are to explore the latest advancements in the following field:

  • Details of chip shaping under machining of high-strength and unconventional materials;
  • Physical phenomenon of cutting and abrasive processing;
  • Modern designs of cutting and abrasive tools;
  • The use of effective technological environments, such as near-dry cutting, minimum cooling and lubrication, high-pressure cooling, etc.;
  • The impact of cutting and abrasive processing on the machined surface texture and the surface layer integrity;
  • Development of high-performance and high-speed cutting;
  • Friction and wear behavior of the surface machined.

Laser–MIG hybrid welding–brazing was used to weld 304 stainless steel and 6061-T6 aluminum alloy with a thickness of 2 mm.

Laser–MIG hybrid welding–brazing was used to weld 304 stainless steel and 6061-T6 aluminum alloy with a thickness of 2 mm. The microstructure, morphology, chemical composition and corrosion behavior of the samples after high-temperature oxidation were investigated. The results reveal that the 304/6061 dissimilar joint had a thicker intermetallic compound layer (7–8 μm) during high-temperature oxidation (HTO) treatment than the sample without HTO treatment (2–3 μm). The oxide film thickness of the 6061 side of the weld joint treated by HTO (2401 nm) increased compared to the samples (181.1 nm) without HTO treatment. Unlike other metals treated by high-temperature oxidation, the high-temperature treatment process in this paper can reduce the corrosion resistance of the base metal and dissimilar joints, and the sequence of the corrosion current density was weld (HTO) >weld>6061 (HTO) >6061>304 (HTO) >304.
