“…The experimental result of threshold pressure is 54 kPa when the volume fraction is 12%, while the predictive value is 52.6 kPa calculated by Eq. (5). As shown in Table 4, the maximum deviation between the measuring threshold pressure and that of model prediction is about 4.6%.…”

“…In recent years, a number of techniques were developed which include powder metallurgy and the spray deposition and so on [3,4]. Liquid metal infiltration process is one of efficient methods for fabricating C sf /Mg composites due to their significant potential at low costs [5]. Previous work on the infiltration has been conducted thoroughly on process and process modeling.…”

The deformation and microstructure evolution behavior of 15 vol. % short carbon fiber reinforced AZ91D composites (C sf /AZ91D) were investigated by hot compression test. An obvious dynamic recrystallization (DRX) was found in the matrix alloy, and the recrystallized grains around the fibers were finer than those in the alloy. The average grain size and volume fraction of the recrystallized grain increases with the increase of deformation temperature or the decrease of strain rate.The volume fraction of the recrystallized grain increases with increasing strain in a rapid-slow manner. By regression analysis on these results, a constitutive model was developed for the first time in attempt to quantitatively evaluate the effect of temperature, strain and strain rate on the DRX behaviors. The calculated average grain size and volume fraction of the recrystallized grains are in good agreement with the experimental ones, thereby validating the accuracy of the developed model.

“…However, the contribution of the nanosized particles on increasing the YS mainly is attributed to the grain refinement effect and Orowan strengthening mechanism. [8][9][10] Meanwhile, some study illustrated that the addition of the metastable nano-size particulates is an effective approach to improve the ductility of PMMCs. 3 Therefore, the good ductility and high strength of PMMCs could be retained or even improved in hybrid SiCp (a little amount of nano-and micron SiCp) reinforced magnesium matrix composites.…”

In this work, we systematically investigate the influence of the volume ratios of hybrid SiC particles (SiCp) on the microstructural characteristics and the room temperature tensile responses of as-cast AZ31B magnesium matrix composites. As the volume ratio of micron and nano-SiCp is 9:1, a significant grain refinement effect is achieved. This is due to both the fairly uniform distribution and refining effect of hybrid SiCp. The micron SiCp distributes along the grain boundaries, while nano-SiCp is mainly distributed around the micron SiCp. Due to grain refinement strengthening and ceramic phase-strengthening effects, the room temperature tensile property of N-1 ? M5-9 has the optimal value of YS157-UTS195 MPa-EL0.92 %.
