Friction and Wear of Extrusion Dies Under Extreme Transient High-Temperature Conditions in the Extrusion of a Novel Nickel-Based High-Temperature Powder Alloy

Lubricants
During the extrusion of novel nickel-based powder superalloy bars, the die is subjected to elevated temperatures, high pressures, and severe friction, which readily lead to abrasive wear and thermal-fatigue damage.

A minimalist model of terminal lakes: Qinghai Lake (China) and Lake Chad (N Africa)

Hydrology Research, 2013
The ratio of the areas of a terminal lake to its total basin provides a geomorphological measure, which characterises the geobotanical state of water limited climates. A minimalist model of this lake area ratio is introduced combining the water balances of lake and land, the Budyko–Schreiber rainfall–runoff chain over land and, as a closure, the land ...
