A novel 3D printing route to fabricate continuous fiber reinforced metal matrix composite (CFRMMC) is proposed in this paper. It is distinguished from the 3D printing process of polymer matrix composite that utilizes the pressure inside the nozzle to combine the matrix with the fiber. This process combines the metallic matrix with the continuous fiber by utilizing the wetting and wicking performances of raw materials to form the compact internal structures and proper fiber-matrix interfaces. CF/Pb50Sn50 composites were printed with the Pb50Sn50 alloy wire and modified continuous carbon fiber. The mechanical properties of the composite specimens were studied, and the ultimate tensile strength reached 236.7 MPa, which was 7.1 times that of Pb50Sn50 alloy. The fracture and interfacial microstructure were investigated and analyzed. The relationships between mechanical properties and interfacial reactions were discussed. With the optimized process parameters, several composites parts were printed to demonstrate the advantages of low cost, short fabrication period and flexibility in fabrication of complex structures.

Lightweight alloys with high performance have become increasing popular in the world of materials engineering and science. In order to obtain high strength for an aluminum matrix alloy, the metal fiber in this work was embedded into the Al-Si-Cu matrix through a vacuum suction casting (VSC) process. Two different metal wires, i.e., copper-coated/copper-uncoated 304 stainless steel, separately, were used to prepare the Al-Si-Cu matrix composite. A microstructure investigation was conducted to study the interface reaction between the metal fiber and the matrix. The results show that the copper-coated wire was conducive to a tight connection for the metal fiber and the matrix, and it can greatly improve the comprehensive properties of the composite. The copper-coated, metal-fiber-reinforced Al-Si-Cu matrix (CC-Mf/Al) composite was further prepared with a different fiber diameter. In order to investigate the effect of the fiber diameter on the microstructure and properties, a microstructure observation of the CC-Mf/Al composite was conducted using scanning electron microscopy (SEM). Properties testing was carried out using a P300 electronic universal testing machine, a MHVD-1000IS microhardness tester and a FT300 resistivity tester. The experimental data indicate that the mechanical properties of the composite increase first and then decrease as the diameter of the fiber increases. When the diameter of the copper-coated fiber is 0.1 mm, i.e., a volume fraction of 0.17 %, the tensile strength of the CC-Mf/Al composites reaches a maximum of 341.04 MPa, which is 49.33 % higher than that of the original aluminum alloy. The elongation and microhardness are 54.24 mm and 129.1 HV, respectively. The resistivity of the CC-Mf/Al composites is lower than that of the copper-uncoated metal fiber-reinforced Al-Si-Cu aluminum matrix (CU-Mf/Al) composite. Keywords: vacuum suction casting, CC-Mf/Al and CU-Mf/Al composite,microstructure, mechanical properties Visoko kvalitetne lahke Al zlitine postajajo vse bolj popularne na podro~ju in`eniringa in znanosti materialov. Avtorji so zato, da bi izdelali lahek kompozitni material z visoko trdnostjo, v matrico na osnovi Al-Si-Cu vgradili kovinska vlakna. Za to so uporabili postopek vakuumskega sesalnega litja (VSC). Za izdelavo kompozita z Al-Si-Cu matrico (CC-Mf/Al) so izbrali dve razli~ni vrsti kovinskih vlaken in sicer: z bakrom prevle~eno in neprevle~eno jekleno`ico iz nerjavnega jekla tipa 304. Izvedli so mikrostrukturne preiskave in {tudirali reakcije na meji med kovinskimi vlakni in matrico. Rezultati so pokazali, da je matrica, ki vsebuje z bakrom prevle~ena vlakna, v celoti prevodna, kar je mo~no izbolj{alo lastnosti kompozita. Nadalje so izdelovali {e CC-Mf/Al kompozite, oja~ane z jeklenimi vlakni razli~ne debeline. Vpliv debeline vlaken na mikrostrukturo in lastnosti CC-Mf/Al so analizirali z vrsti~nim elektronskim mikroskopom (SEM). Mehanske lastnosti kompozitov so dolo~ili s pomo~jo elektronskega univerzalnega trgalnega stroja P300. Trdoto kompozitov so dolo~ili na merilniku m...

“…The contact pressure between the polishing tool and the contact surface needs to be measured using a pressure sensor, since the conventional polishing tool is inelastic [6,7]. Compared with the free abrasive particle polishing process, the fixed abrasive polishing process has a large number of abrasive grains [8]. This type of material has a high material removal rate and a good self-twisting effect.…”

In order to achieve high quality polishing of a M300 mold steel curved surface, an elastic abrasive is introduced in this paper and its polishing parameters are optimized so that the mirror roughness can be achieved. Based on the Preston equation and Hertz Contact Theory, the theoretical material removal rate (MRR) equation for surface polishing of elastic abrasives is obtained. The effects of process parameters on MRR are analyzed and the polishing parameters to be optimized are as follows: particle size (S), rotational speed (Wt), cutting depth (Ap) and feed speed (Vf). The Taguchi method is applied to design the orthogonal experiment with four factors and three levels. The influence degree of various factors on the roughness of the polished surface and the combination of parameters to be optimized were obtained by the signal-to-noise ratio method. The particle swarm optimization algorithm optimized with the back propagation (BP) neural network algorithm (PSO-BP) is used to optimize the polishing parameters. The results show that the rotational speed has the greatest influence on the roughness, the influence degree of abrasive particle size is greater than that of feed speed, and cutting depth has the least influence. The optimum parameters are as follows: particle size (S) = #1200, rotational speed (Wt) = 4500 rpm, cutting depth (Ap) = 0.25 mm and feed speed (Vf) = 0.8 mm/min. The roughness of the surface polishing with optimum parameters is reduced to 0.021 μm.
