“…The fusion zones of dissimilar metal joints of most steels with Cu alloys manufactured by laser welding also exhibit the presence of discrete ε-Cu and γ-Fe or α-Fe zones, respectively. Furthermore, the accumulation of liquefied copper along the already solidified grain boundaries of the steel materials can lead to hot cracking [20,21,24,25]. This has also been shown in PBF-LB/M for tool steel 1.2709 contaminated with copper alloy particles [26].…”

“…The predominant defects in the steel area around the copper inlet were mostly vertical cracks, which accumulated in some cases and formed major voids. As the defects only occurred in the multi-material region of the nozzles, an increased copper concentration in the steel melt pool could lead to discrete liquid copper accumulations at emerging steel grain boundaries during solidification [20,21,24,25]. Thus, defects are likely to be hot cracks due to foreign particles [26], which appear to cause larger defects (Figure 5, defect no.…”

“…Depending on the element concentration and cooling rates, secondary and tertiary phase separation can occur, leading mainly to the presence of discrete Ferich and Cu-rich zones. This effect is also used to increase the mechanical properties of stainless steel 1.4542 and other chromium-nickel-copper steels through precipitation of the face-centered cubic (fcc) ε-Cu phase [19][20][21][22][23]. The fusion zones of dissimilar metal joints of most steels with Cu alloys manufactured by laser welding also exhibit the presence of discrete ε-Cu and γ-Fe or α-Fe zones, respectively.…”

Additive Manufacturing (AM) allows the manufacturing of functionally graded materials (FGM). This includes compositional grading, which enables the allocation of desired materials corresponding to local product requirements. An upcoming AM process for the creation of metal-based FGMs is laser-based powder bed fusion (PBF-LB/M) utilized for multi-material manufacturing (MM). Three-dimensional multi-material approaches for PBF-LB/M are stated to have a manufacturing readiness level (MRL) of 4 to 5. In this paper, an advancement of multi-material technology is presented by realizing an industry-relevant complex part as a prototype made by PBF-LB/M. Hence, a multi-material injection nozzle consisting of tool steel and a copper alloy was manufactured in a continuous PBF-LB/M process. Single material regions showed qualities similar to the ones resulting from mono-material processes. A geometrically defined transition zone between the two materials was achieved that showed slightly higher porosity than mono-material regions. Nevertheless, defects such as porosity, cracks, and material cross-contamination were detected and must be overcome in further MM technology development.

“…The combination of these materials shows a liquid-phase separation during the rapid solidification, resulting in dispersed droplets of both components. Depending on the concentration of the elements and the cooling rates, secondary and tertiary phase separations may occur, leading to the presence of distinct Fe-rich and Cu-rich zones [23][24][25][26][27]. Thus, in laser-welded dissimilar metal joints, such as low-alloy, stainless, and tool steels with Cu alloys, the fusion zones are characterized by discrete ϵ-Cu and γ-Fe or α-Fe zones.…”

Power bed fusion of metals using a laser beam (PBF-LB/M) offers unique possibilities to manufacture functionally graded materials (FGM) consisting of different alloys. These so-called multi-material parts enable their material properties to be tailored to local material requirements. In this paper, a new methodical approach for the production of metal FGM with transition zones oriented in different directions and manufacturing sequences of the different materials is investigated. Existing approaches for the manufacturing of these transition zones were enhanced with graded parameter variations, spatial laser movement modulation techniques (wobbling), and geometric approximations using a step structure. For the validation of the approach and the characterization of the transition zones, the manufactured samples were investigated and characterized using optical microscopy and hardness profile measurements. Furthermore, the density of the transition zones was analyzed by image data processing. The feasibility of the presented methods is shown and the production of defect-free transition zones with controlled expansions for functionally graded materials via PBF-LB/M achieved

“…Mechanical properties and corrosion resistance could be significantly improved through deformation and aging. The optimum corrosion resistance can be attained by the dissolution of all the precipitates and homogeneous distribution of alloying elements in the solid solution [10]. The resulting mechanical properties of many of the high-strength alloys depend on the use of one or more of these induced effects.…”

Weathering steels developed under the name COR-TEN steels, established themselves as a promising material to meet the demand for atmospheric corrosion resistance and eliminate the need for painting. COR-TEN steel is resistant to corrosive effect of weather such as rain, snow, ice, fog, etc. A coating of dark brown oxidation is developed over the metal surface, when it comes in contact with the environment thereby inhibiting the deeper penetration and negating the need for painting and reducing the rust-prevention cost over the years. Thus the steel is allowed to rust which forms a protective layer and slows down the rate of corrosion. The present study emphasizes the age hardening behavior of COR-TEN steel. The steel was subjected to solution treatment at 1000°C following accelerated cooling with water, oil and air. The oil quenched steel was then subjected to aging treatment at 400°C and 500°C for various times ranging from 5 min to 1500 min followed by water quenching. In order to ascertain the response to aging hardness measurement were conducted by employing a load of 20 Kgf. Metallographic examinations were also conducted to study the resulting structural transformations in various stages of investigations.
