“…The Ti–Cr based systems would appear to offer a significant opportunity (in combination with Zr, Sn, and Nb, in particular, but other elements may also be useful). For example, the exceptional properties displayed by alloys in the Ti–Cr–Nb system (very low elastic modulus (17–50 GPa), high strength (1580–1700 MPa), and plasticity (75.0–83.5%); together with excellent corrosion resistance) warrant further investigation . In addition, the self‐adjustment of Young's modulus in these types of alloys is also a very interesting attribute that could be exploited to great effect in metal AM.…”

Metal additive manufacturing (AM) is an innovative manufacturing technique, which builds parts incrementally layer by layer. Thus, metal AM has inherent advantages in part complexity, time, and waste saving. However, due to its complex thermal cycle and rapid solidification during processing, the alloys well suit and commercially used for metal AM today are limited. Therefore, it is important to understand the alloying strategy and current progress with materials performance to consider alloy development for metal AM. This review presents the current range of alloys available for metal AM, including titanium, steel, nickel, aluminum, less common alloys (including Mg alloys, metal matrix composites alloys, and low melting point alloys), and compositionally complex alloys (including bulk metallic glasses and high entropy alloys) with a focus on the relationship between compositions, processing, microstructures, and properties of each alloy system. In addition, some promising alloy systems for metal AM are highlighted. Approaches for designing and optimizing new materials for metal AM have been summarized.

“…An introduction of niobium, silicon, and titanium atoms into Zr results in an increase of the chemical stability of the system [15,16], etc. Therefore, the problem of increasing the surface mechanical characteris tics by the formation of nanostructural multilayer [17][18][19][20] and multicomponent [9,13,16,21] coatings of car bides, nitrides, borides, and silicides of transition metals is profitable from the practical point of view.…”

“…In the last years particular attention has been given to the development of superhard nanostructural coat ings that are produced using three-(Ti-Nb-N, Ti-Cr-N, Zr-Ti-N) [4,11,12,17], four-(Zr-Ti-Si-N) [16,18] or five-(Zr-Nb-Ti-Cr-N) component systems [19,22]. The structures and properties as well as the possibilities of thermal stabilization of the phase compositions of such alloyed condensates are poorly known for the present.…”

“…The structures and properties as well as the possibilities of thermal stabilization of the phase compositions of such alloyed condensates are poorly known for the present. But as a whole the above materials exhibit a higher hardness (up to 36-50 GPa) [5,6,8,17], elasticity (300-425 GPa) [3,8], and thermal stability [5]. Among these studies the research of Taiwan scientists [19] stands out, where the five component coatings (Zr-Ti-Cr-Nb)N exhibits a low hardness (2.5 GPa) and Young modulus (93 GPa), which is even below the values of the ZrTiCrNb (H = 4.7 GPa) target produced by arc melting according to the authors version.…”

Abstract-Structure and properties of (Zr-Ti-Cr-Nb)N multicomponent nanostructured coatings fab ricated by a vacuum arc deposition have been investigated. It has been found that the coatings thickness attained 6.2 μm, hardness and indentation load that is responsible for the stress exceeding cohesion strength of coatings were H = 43.7 GPa and L c = 62.06 N, respectively. In coatings structures have been identified that consist of three interstitial phases having cubic, hexagonal, and tetragonal lattices. The nanocrystallites sizes were from 4 to 7.3 nm. The results of the SEM, TEM, EDS, and XRD analysis have been also considered.

“…Ti-6Al-4V can be modified to have better corrosion resistance by replacing V with Nb, Zr or Ta [54]. A recent study by Slokar [76] designed Ti alloys using different amount of Cr and Nb. The author and colleagues produced a-b Ti alloys possessed low elastic modulus (17-50 GPa), high strength (1580-1700 MPa) and high corrosion resistance.…”
