“…In situ synthesis process can be divided into the state of the original reaction phase gas -liquid reactions , liquid -solid reaction , liquid -liquid reactions [1][2][3].In situ reaction particles have merits including fine particles, uniform distribution in the matrix, as well as the particle surface is not contaminated, and good substrate wettability and adhesion, which attracts more and more attentions of scholars at home and abroad [4][5][6]. Studies on material properties under the combined magnetic field not only has the important theoretical significance, but also has important economic significance.…”

Abstract. The effects of the magnetic field on microstructures and wear properties of aluminum matrix composites are studied based on K2ZrF6-Al system. The results show that under the combination of magnetic field, melt can generate a forced exercise, which promotes melt dynamics changes in conditions, and thus playing the role of refined particles, changes in morphology and distribution. The SEM images of worn surface show that there is a serious adhesion and deformation within the 6A02 matrix alloy, which is adhesive wear and delamination abrasive, and the wear type of Al3Zr/6A02 composite materials is abrasive wear. Mechanical properties of Al3Zr/6A02 composites are greatly improved under the effect of the combination of magnetic field, and the tensile strength increases from 239.8MPa to 400.6MPa with a 67% increase. The area of plastic deformation is reduced, but is still ductile fracture.

“…Of several routes processing the discontinuous MMCs including ingot metallurgy, high pressure or vacuum infiltration method, squeeze casting, etc, [1][2][3][4][5] powder metallurgy (PM) [6][7][8] is the most preferred one by: (a) ability producing the near net-shaped components, (b) easy control of the reinforcement volume fraction, and (c) suppression of chemical reaction at the interface between matrix and reinforcement due to relatively low processing temperature. In general, conventional metal working processes such as extrusion are performed on the as-PM processed discontinuous MMCs in order to obtain not only fully dense materials but the desired microstructures and mechanical properties.…”

The 6061 Al-10 vol% SiC w composites were prepared by powder metallurgy with the powders having the different sizes, i.e. < 30 µm and 30 µm <. The composites were subjected to equal channel angular pressing (ECAP) under various conditions and the microstuctural changes during ECAP were examined. A special focus was made on the effect of ECAP conditions on the distribution of SiC whiskers. The present investigation was aimed at exploring the feasibility of ECAP as a post working process for manufacturing the discontinuous metal matrix composites. The microstructural examination and the microhardness measurement of the ECAPed samples suggested that the optimum combination of the uniform microstructure and enhanced mechanical properties would be obtained by (a) using the powders having the smaller size, (b) decreasing ECAP temperature, and (c) repeating ECAP.
