“…The melting temperature of ABS plastic is 200 °C, what is making it ideal for usage in relatively safe and easy-to-use machinery (e.g., in the household operating machines, at which the reliability is very important). [8] This is an ideal plastic for making cheap prototypes and architectural models for technicians or research workshops, as well as for making affordable medical prostheses or material handling gadgets. The natural characteristics of this material, such as its stiffness and strength, as well as its ability to resists to heat, make the material very suitable for various practical applications.…”

The article deals with the experimental investigation of the influence of material volume of a lattice structure on bending stress. FDM (Fused Deposition modelling) technique and ABS (Acrylonitrile Butadiene Styrene) material were selected for the samples production. Three types of samples with the same simple lattice structure and the same size of a basic cell 5 mm, but differ in a material volume ratio, were analysed experimentally. Minimally six pieces of the samples of each volume ratio were produced and tested using the ZWICK 1456 testing machine at an ambient temperature of 22 °C and at a relative humidity of 60 % according to the standard EN ISO 604. The stress-strain diagrams have been plotted and the values of maximum stresses have been tabled. The measured data were statistically processed, and average values of bending stresses were calculated. Based on the results the behaviour of the structure has been mathematically described, while the results showed that the dependency has an exponential trend.

“…Coarse intermetallic particles are observed both inside the grains and on their boundaries (Figure 3a,c). These particles were identified as η-MgZn 2 , θ-Al 2 Cu and S-Al 2 CuMg phases, which are commonly inherent in the AA7075 [37].…”

“…A hybrid powder bed/wire EBAM allowed a fully dense CuAl-B 4 C FGM to be obtained [36]. Another attempt was devoted to growing an AA5356 wall on an AA7075 substrate [37] in order to improve the corrosion resistance of the latter. Admixing Mg into the AA7075/AA5356 transition zone proved to be detrimental for its corrosion resistance due to the precipitation of anodic Al-Cu-Zn-Mg and Mg 2 Si particles.…”

Microstructure and Corrosion Resistance of AA4047/AA7075 Transition Zone Formed Using Electron Beam Wire-Feed Additive Manufacturing

et al. 2021

View full text Add to dashboard Cite

A gradient transition zone was obtained using electron beam deposition from AA4047 wire on AA7075 substrate and characterized for microstructures, tensile strength and corrosion resistance. The microstructure of the transition zone was composed of aluminum alloy grains, Al/Si eutectics and Fe-rich and Si-rich particles. Such a microstructure provided strength comparable to that of AA7075-T42 substrate but more intense corrosion due to the higher amount of anodic Mg2Si particles. The as-deposited AA4047 zone formed above the transition zone was composed of aluminum alloy dendrites and interdendritic Al/Si eutectics with low mechanical strength and high corrosion potential.
