“…Al-based metal matrix composites (AMCs) are very attractive for lightweight applications such as aerospace, military and transport sectors due to high specific strength, good fatigue properties and wear resistance [1][2][3][4][5]. In addition, AMCs offer the possibility to tailor their properties to meet specific requirements [2][3][4][5][6].…”

Abstract:The effect of Mg-7.4%Al reinforcement particle size on the microstructure and mechanical properties in pure Al matrix composites was investigated. The samples were prepared by hot consolidation using 10 vol.% reinforcement in different size ranges, D, 0 < D < 20 µm (0-20 µm), 20 ≤ D < 40 µm (20-40 µm), 40 ≤ D < 80 µm (40-80 µm) and 80 ≤ D < 100 µm (80-100 µm). The result reveals that particle size has a strong influence on the yield strength, ultimate tensile strength and percentage elongation. As the particle size decreases from 80 ≤ D < 100 µm to 0 < D < 20 µm, both tensile strength and ductility increases from 195 MPa to 295 MPa and 3% to 4% respectively, due to the reduced ligament size and particle fracturing. Wear test results also corroborate the size effect, where accelerated wear is observed in the composite samples reinforced with coarse particles.

“…The mixing of additives with the matrix is generally carried out by manual mixing (hand mixing or agate mortar). However, mixing by mechanical milling (MM) has shown significant improvement in the strength and ductility of the composite materials due to the uniform distribution of the reinforcement/foreign particles [31][32][33][34][35][36][37]. Even though several studies have focused on the improvement of flexural strength and fracture toughness of the Al 2 O 3 -based ceramic composites, a systematic study dealing with the microstructural evolution and structure-property correlation is lacking.…”

Al 2 O 3 -10TiC composites were fabricated through the powder metallurgical process (mechanical milling combined with spark plasma sintering) with the addition of Ni/Nb as metallic binders. The effect of binder addition (Ni/Nb) on the processing, microstructure, and mechanical and tribological properties of the bulk-sintered composite samples was investigated. The microstructure of the composite reveals a homogeneous distribution of the TiC particles in the Al 2 O 3 matrix. However, the presence of Ni/Nb was not traceable, owing to the small amounts of Ni/Nb addition. Hardness and density of the composite samples increase with the increasing addition of Nb (up to 2 wt. % Nb). Any further increase in the Nb content (3 wt. %) decreases both the hardness and the wear resistance. However, in case of Ni as binder, both the hardness and wear resistance increases with the increase in the Ni content from 1 wt. % to 3 wt. %. However, the composite samples with Nb as binder show improved hardness and wear resistance compared to the composites with Ni as binder.

Additive Manufacturing: Reproducibility of Metallic Parts

Abstract:The present study deals with the properties of five different metals/alloys (Al-12Si, Cu-10Sn and 316L-face centered cubic structure, CoCrMo and commercially pure Ti (CP-Ti)-hexagonal closed packed structure) fabricated by selective laser melting. The room temperature tensile properties of Al-12Si samples show good consistency in results within the experimental errors. Similar reproducible results were observed for sliding wear and corrosion experiments. The other metal/alloy systems also show repeatable tensile properties, with the tensile curves overlapping until the yield point. The curves may then follow the same path or show a marginal deviation (~10 MPa) until they reach the ultimate tensile strength and a negligible difference in ductility levels (of~0.3%) is observed between the samples. The results show that selective laser melting is a reliable fabrication method to produce metallic materials with consistent and reproducible properties.
