(Ⅱ) --Pore ratio and compressive strength Abstract: This study was focussed upon the porosity (pore ratio) and compressive strength of the raw material, which was mixed the rare earth concentrates with two kinds of carbon reductants, A 0 and B 0, and pressed into compacts. After the compacts were roasted at 773 K, 1 573~1 773 K respectively, their porosity......
) and pressures (13-812 MPa) in a hydrothermal diamond anvil cell (HDAC) reveals the preservation mechanism of porosity in deep carbonate reservoirs in the northeastern Sichuan Basin. The carbonate... and burial dissolution may not be the dominant diagenesis in the origin of porosity. Thin section photomicrographs observations in Changxing and Feixianguan Formations demonstrate that eogenetic pores......

Afterwards, a computational code is developed to solve the same problem by the IMPES method and the results of streamline simulation... words: two-phase flow; porous media; fractured reservoirs; streamline simulation; dual porosity; implicit pressure-explicit saturation 1 Introduction Increased global demand for fossil fuels presents......
to pull-out of the irregular shaped composite particles. The 50% SiC MMC suffers from composite particle fracture porosity after high pressure die casting (HPDC). Key words: CSIR–RCS; HPDC; SiC; F condition; T6 condition; wear rate; hardness; porosity 1 Introduction Metal matrix composites (MMCs) are natural materials of choice for wear sensitive applications. Attractiveness for making MMC......
by the solid-gas eutectic solidification process. The anisotropy of tensile properties and the porosity of ordered porous copper at room temperature were investigated. In order to discuss the effects of porosity and tensile direction on ultimate tensile strength, the stress concentration models were established. The results show that the tensile properties of ordered porous copper depend......
