“…In a ductile-brittle process, during the milling, the particles of the powders are subject to plastic deformation, and fracture with the absence of cold welding, due to the high capacity of the Vanadis ® 8 to absorb plastic deformation. In the first milling stage, ductile particles suffer deformation, while fragile particles, fragmentation 16,28 .…”

“…The Figure 8 shows the microstructural evolution of the high energy ball milling in a ductile-brittle system, where it is observed that the impact between the milling spheres promotes the collision of the particles of the ceramic material with the metallic material, resulting in a region of generalized stresses in the ductile particles, which leads to rupture, by combining the ductile-brittle process 16,28 . In addition, this form of analysis has the purpose of meeting economic aspects, since that this type of study can be extended to other high energy ball milling processes, with the objective to reuse other types of materials, with high economic value added.…”

The Vanadis ® 8 is a tool steel used in the manufacture of dies, punches and tools. It has a high carbon content combined with chromium, molybdenum and vanadium, and presents good performance in its mechanical properties. Usually, its chips obtained by machining are sold to companies that use remelting. However, this technique is considered expensive and harmful to the environment. Therefore, this work aimed to analyze the efficiency of the addition of vanadium carbide (VC) and molybdenum carbide (Mo 2 C) in the high energy ball milling of the Vanadis ® 8 steel. Microstructural analysis were performed in the pure steel and with 3% of VC and Mo 2 C additions. The milling parameters used were: speed of 350 rpm, ball-to-powder weight ratio of 15:1 and times of 4, 8 and 12 hours. The results indicated that the Vanadis ® 8 steel milled with VC presented the best microstructural results in all of the conducted tests.

In the present study, the authors used sessile drop method to simulate the contacting and infiltration behavior between Al melt and Al–B4C composite. In order to track the penetration distance of the metal melt infiltrate into the Al-B4C composite matrix when the infiltration is not obvious, element Si was added into the metal melt as the tracer agent. The Al-10%Si melt was dropped onto the Al-B4C composite substrate at 913K. The changes of droplet bottom size, height, and contact angle during the spreading and penetration with Al-B4C composite substrate surface are investigated by infiltration experiment equipment. The process of the droplet infiltrating into the Al-B4C composite can be divided into two stages: (a) a slow infiltration stage that the contact angle changes slowly; (b) a quick infiltration stage with the rapidly-changed contact angle. The content of B4C and the pores in the composite plays an important role on the infiltration of the droplet. The higher the density, the easier the infiltration proceeds.

“…Norul AmierahBinti Nor Zamani et al [17] studied the mechanical characterization of Al+Gr+Al 2 O 3 hybrid composites and stated that inclusions of Al 2 O 3 and Gr particles improve the mechanical behavior of the AMCs considerably. Nazli Akcamli [18] developed Al-8.5 wt% Si-3.5 wt% Cu matrix composites and reported that inclusion of B 4 C particles results in significant enhancement in mechanical behavior of the produced composites. Vipin Kumar Sharma [19] synthesized Al6061-Al 2 O 3 -SiC-CeO 2 composites by PM route and concluded that a rise in reinforcement wt.% enhances the composites mechanical behavior drastically.…”

In this paper, Al-Fe-Si-Zn-Cu (AA8079) matrix composites with several weight percentages of B4C (0, 5, 10, and 15) were synthesized by powder metallurgy (PM). The essential amount of powders was milled to yield different compositions such as AA8079, AA8079-5 wt.%B4C, AA8079-10 wt.%B4C, and AA8079-15 wt.%B4C. The influence of powder metallurgy parameters on properties’ density, hardness, and compressive strength was examined. The green compacts were produced at three various pressures: 300 MPa, 400 MPa, and 500 MPa. The fabricated green compacts were sintered at 375 °C, 475 °C, and 575 °C for the time period of 1, 2 and 3 h, respectively. Furthermore, the sintered samples were subjected to X-ray diffraction (XRD) analysis, Energy Dispersive Analysis (EDAX), and Scanning Electron Microscope (SEM) examinations. The SEM examination confirmed the uniform dispersal of B4C reinforcement with AA8079 matrix. Corrosion behavior of the composites samples was explored. From the studies, it is witnessed that the rise in PM process parameters enhances the density, hardness, compressive strength, and corrosion resistance.
