“…As the attempts of modifying mechanical properties of Ti and its alloys in the SLM process by additions of refractory metals such as Mo [13] and Re [14] appeared successful, this work considers further investigations of selective laser melted Ti-Re alloys.…”

“…Rhenium, as a refractory metal with excellent tensile and creep strength over a wide temperature range (up to 2000°C) and wear properties [16], seems to be highly effective in improving hightemperature durability of Ti alloys. So far, the papers concerning the effect of rhenium addition on Ti properties are limited [14,17]. Chlebus et al [14] and Kovtun and Ul'yanov [17] found that rhenium considerably increases hardness and strength of Ti at room temperature.…”

These values are very close to nickel-based superalloys used for advanced turbine engines with YS often in the range of 900-1300 MPa and UTS of 1200-1600 MPa [18].…”

Selective laser melting (SLM) is an additive manufacturing process that enables novel alloy production by combining metals with significantly different physical properties. In this paper, the hot corrosion behavior of Ti-Re alloys fabricated by SLM was studied in a mixture of Na 2 SO 4 and NaCl salts at 600°C. The morphology and composition of the corrosion products were characterized by scanning electron microscopy with energy-dispersive X-ray spectroscopy and X-ray diffraction to understand the degradation mechanisms. It has been shown that the hot corrosion resistance of Ti-Re alloys was influenced by the chemical inhomogeneity of the oxide scale resulting from the presence of rhenium particles undissolved during the SLM process.

A Review of Metal Fabricated with Laser‐ and Powder‐Bed Based Additive Manufacturing Techniques: Process, Nomenclature, Materials, Achievable Properties, and its Utilization in the Medical Sector

Additive manufacturing has multiple advantages over conventional fabrication techniques, such as the geometrical freedom and, to a great extent, the omission of tooling equipment. Hence, futuristic designs and non-standard topology-optimized structures can be fabricated without causing noteworthy extra cost, since the geometrical complexity is, exaggeratedly spoken, for free. The manufacturing time and the amount of required raw material are the key criteria, which determine the expenses. What at first glance appears as an engineer's dream, introduces its complexity in the description of the material's characteristics and their volatility to the manufacturing conditions. Within this study, the main properties (i.e., surface hardness, tensile, and compression strength, as well as fracture toughness) and their anisotropic and inhomogeneous nature are addressed. Detailed overviews of the progress to date for aluminum, iron, titanium, cobalt, and nickel based raw materials are provided. Furthermore, an overview about the state-of-the-art in the medical sector is included, comprising the areas of utilization and several trail studies.
