Two-stage super vacuum (19 mbar) assisted high pressure die casting (HPDC) was achieved by evacuating from the die cavity and the shot sleeve simultaneously. The effect of super vacuum assisted HPDC on the repeatability of the tensile properties of Al-Si-

Vacuum sintered lunar regolith simulant: Pore-forming and thermal conductivity
Ceramics International, 2019Lunar regolith molding technologies are receiving an increasing attention in lunar exploration program. Most studies are carried out in the air on earth, ignored the effects of high vacuum (~ 10-12 mbar) on the lunar surface.

RETRACTED: Mechanism analysis on ground settlement induced by vacuum removal
The International Journal of Electrical Engineering & Education, 2019Due to the settlement hazards induced by the soft clayey soils, vacuum preloading has been widely used all over the world. Many studies focus on the process of vacuum application but the process of vacuum removal is generally ignored.

Vacuum systems for vacuum microbalances
Vacuum, 1985Abstract Five types of vacuum balances are in use today: electromagnetically compensated beam balances; magnetic suspension balances; spring balances; quartz resonators and strain gauges. The last two types are usually arranged in bell jar apparatus. In the case of suspension balances, a small vessel includes the permanent magnet and the sample. Beam
