Special Issue Information

Dear Colleagues,

The main aim of this Special Issue is to present the state of the research on the production of advanced industrial materials, modeling, processing, and characterization.

The objects of this research should report on investigations carried out using very specific models, methods, and/or instruments. The knowledge presented in this Special Issue, alongside the methods considered, the technical systems, and their applications, has strong potential to bring together and make an impact on researchers as well as other professionals. The knowledge presented will contribute insights into as yet unanswered questions and may lead to the discovery new questions.

Contributions should focus primarily on the following:

  • Modeling and characterization of materials;
  • Production and processing of advanced materials;
  • Quality and reliability of industrial materials;
  • Optimization and characterization of surface properties;
  • Testing and inspection of advanced materials;
  • Environmental aspects of material production;
  • Advances in the production of metals, plastics, composites, etc.;
  • Processing for advanced properties in manufacturing;
  • Advances in additive production technologies.

The object of this study is welded joints of AISI 321 and Ti-6Al-4V, obtained by diffusion welding on developed conical surfaces. The problem of creating bimetallic joints of AISI 321 and Ti-6Al-4V with developed conical contact surfaces, using diffusion welding through an intermediate Electrolytic Tough Pitch Copper (Cu-ETP) copper layer, was solved. The joints were studied using micro-X-ray spectral analysis, microstructural analysis, and mechanical tests. High mutual diffusion of copper and titanium, along with increased concentrations of Cr and V in copper, was detected. The shear strength of the obtained welded joints is 250 MPa and 235 MPa at 30 min and 15 min, respectively, which is higher than the copper layer’s strength (180 MPa). The obtained results are explained by the dislocation diffusion mechanism in the volume of grains and beyond, due to thermal deformations during welding. Under operating conditions of internal pressure and cryogenic temperatures, the strength of the connection is ensured by the entire two-layer structure, and tightness is ensured by a vacuum-tight diffusion connection. The obtained strength of the connection (250 MPa) is sufficient under the specified operating conditions. Analysis of existing solutions in the literature review indicates that industrial application of technology for manufacturing bimetallic adapters from AISI 321 stainless steel and Ti-6Al-4V titanium alloy is limited to butt joints with small geometric dimensions. Studies of the transition zone structure and diffusion processes in bimetallic joints with developed conical contact surfaces enabled determination of factors affecting joint structure and diffusion coefficients. The obtained bimetallic adapters, made of Ti-6Al-4V titanium alloy and AISI 321 stainless steel, can be used to connect titanium high-pressure vessels with stainless steel pipelines. Full article
