“…An aluminum bronze wall was grown on a AISI 321 steel substrate from a Cu-7.5wt.%Al wire using an electron beam wire-feed machine designed and built at the Institute of Strength Physics SB RAS ( Figure 1) [6]. The stainless-steel substrate possesses low thermal conductivity, and therefore it was used in order to reduce risk of cracking at the substrate/coating fusion line [44].…”

An as-cast macrostructure of electron beam additively manufactured metallic materials was represented by coarse columnar grains whose axes were inclined at 25° with respect to the substrate’s plane. One part of the as-grown samples was annealed to form a coarse grain microstructure while the other part was pre-deformed by forging and then annealed what allowed obtaining recrystallized microstructures with small grains and multiple annealing twin boundaries. This sample showed both high strength and plasticity during the tensile tests. These tensile tests demonstrated also two-stage stress-strain curves as depended on their strain hardening rates. High and low strain hardening rates corresponded to a twinning-dominated deformation at stage II and dislocation-base deformation at stage III. A submicron size strain-induced grain-subgrain microstructure was formed in the vicinity of a necked zone as a result of combined twinning/dislocation grain refining.

“…Traditional powder metallurgy [1] as well as arc melting technologies [2] are mainly used for this material. The most advanced technologies used for manufacturing products from copper alloys are wire arc additive manufacturing [3,4], selective laser melting (SLM) [5,6], and electron beam additive manufacturing (EBAM) [7]. The latest seems the most promising since it needs vacuum and therefore the risk of interlayer oxidizing is excluded.…”

Friction Behavior of Aluminum Bronze Reinforced by Boron Carbide Particles

A promising composite material for tribotechnical applications based on aluminum bronze with reinforcing boron carbide particles fabricated by a special electron beam additive deposition technique was studied experimentally and numerically. Tribological experiments showed that reinforcing by carbide particles allowed reducing the coefficient of friction from 0.26 to 0.19 and improving the wear resistance by 2.2 times. Computer modeling reveals two main factors playing a significant role in the friction behavior of the studied metal matrix composite: the mechanical effect of reinforcing ceramic inclusions and effective hardening of the metal matrix due to the peculiarities of the 3D electron beam printing. The mechanical effect of hardening inclusions determines a more rounded shape of wear particles, preventing wedging, and thereby increasing the stability of friction. Strengthening the metal matrix leads to reducing the number of wear particles.

“…Wire Arc Additive Manufacturing (WAAM) is a new manufacturing technology with which metallic structures can be created by depositing successive layers along a pre-designed route [1][2][3][4][5][6][7]. It provides high deposition and material utilization rate, saves lead time and costs [8], which are advantageous in manufacturing largescale metallic components [9][10][11].…”

“…The Cu-Al alloy made by WAAM have no thermal cracking issues [1]. In general, various reports show that alloys prepared via arc additive manufacturing process perform better than cast alloys [1][2][3][4][5][6][7]. Cu-Al series alloys have excellent mechanical properties, outstanding wear and corrosion resistance are being widely used in oil pipelines, shipbuilding industries and aerospace applications [12,13].…”

In this work, Cu-4.9% Al alloy with little Si (the weight percentage is 1.3%) and little Mn (the weight percentage is 0.8%) was deposited by wire arc additive manufacturing. Microstructure and properties of the deposited alloy was investigated. Microstructural characterization was done using optical microscopy, scanning electron microscopy and transmission electron microscopy. Microstructural investigation revealed that aluminum was enriched at the interlayer (i.e. inside the deposited layers), whereas silicon and manganese were found enriched at the border layers (i.e. at the border of the deposited layers). Evaluation of the mechanical properties showed that the deposited sample had good strength and ductility. The addition of silicon effectively improved the hardness and tensile strength properties of the deposited alloy.
