The effects of boron content on the microstructure and mechanical properties of a directionally solidified Ni-based superalloy were investigated. The increase of boron content significantly increases the amount of γ/γ′ eutectic, impels the format

The effects of C, Zr and Y/Ce on the microstructures and stress rupture properties of a directionally solidified Ni-based superalloys were investigated. The morphology of MC carbides does not change in as-cast alloys, as the C content is increased or

Basaltic rocks from Shuangliao, northeast China include basanite, alkali olivine basalt, transitional basalt and sub-alkaline diabase. Ar–Ar dating shows that the basanites and alkali olivine basalts formed earlier (48.5–51 Ma) than the transitio

The origin of Neoproterozoic intrusions (ca. 860–750 Ma) along the western part of the Yangtze Craton has been the subject of debate in recent years, with two competing models proposed. The plume model argues for an extensional setting and emphasiz
