The microstructure, aging behavior and mechanical properties of cast Mg–3Nd–3Gd–xZn–0.5Zr (x = 0, 0.5, 0.8, 1 wt%) alloys are investigated in this work. Zn–Zr particles with different morphologies form during solution treatment due to the additions Zn. As Zn content increases, number density also increases. Microstructural comparisons peak-aged studied indicate that varying could profoundly inf...

Low-rank coal samples from the Xishanyao Formation in southern Junggar basin of Xinjiang were processed under different negative pressures order to examine microstructural characteristics low-rank reservoirs. The pore structures tested using scanning electron microscopy, low-temperature nitrogen adsorption–desorption, and water saturation centrifugal low-field NMR experiments. results showed th...
