High Temperature Oxidation and Corrosion Properties of High Entropy Superalloys
The present work investigates the high temperature oxidation and corrosion behaviour of high entropy superalloys (HESA). A high content of various solutes in HESA leads to formation of complex oxides, however the Cr and Al activities of HESA are sufficient to promote protective chromia or alumina formation on the surface. By comparing the oxidation and corrosion resistances of a Ni-based supera...
متن کاملImpure altruism and impure selfishness
Altruism refers to a willingness to benefit others, even at one’s own expense. In contrast, selfishness refers to prioritizing one’s own interests with no consideration for others. However, even if an agent is selfish, he might nevertheless act as if he were altruistic out of selfish concerns triggered when his action is observed; that is, he might seek to feel pride in acting altruistically an...
متن کاملImpure Altruism and Impure Selfishness: Online Appendix
We provide an extention of GU model that incorporates a decision maker who is averse to inequality of allocations among other agents. We also provide a detaled discussion on the experiments on dictator games with an exit option.
متن کاملImproving the oxidation resistance of nickel - based superalloys for turbine blades
I. Introduction: Challenges in energy savings for turbines engines Nickel-based superalloys can withstand high temperatures and severe oxidizing conditions, while maintaining superb mechanical properties. Because of this, they are widely used for aerospace and power generation applications. Since higher operating temperature leads to greater cycle efficiency, there are economic and environmenta...
متن کاملRemarks on Impure Quotation*
Quotation marks are ambiguous, although the conventional rules that govern their different uses are similar in that they contain quantifications over quotable expressions. Pure uses are governed by a simple rule: by enclosing any expression within quotation marks one gets a singular term, the quotation, that stands for the enclosed expression. Impure uses are far less simple. In a series of use...
