  • Publication number: 20230295772
    Abstract: Methods for forming metal alloys, including refractory intermetallic alloys, and ceramic composites using reactive synthesis during additive manufacturing (AM) are provided. In the AM processes, an exothermic reaction path is used, such that the heat from the reaction drives the synthesis reaction. Using this approach, component powders that are readily available from commercial vendors or easily synthesized using conventional methods are mixed in selected amounts and subsequently reacted via AM to produce metal alloys or ceramic composites.

  • Publication number: 20150058788
    Abstract: The present invention discloses an information processing method and an electronic device, the method being applicable to an electronic device capable of executing a first application, and the method including: detecting at an instance of time T1 whether there is a first predetermined operation, wherein the first predetermined operation is configured to control the electronic device to present a second interface for displaying a set of second applications satisfying a predetermined condition; determining whether the set of second applications includes the first application; and when it is determined that the set of second applications includes the first application, displaying the first application via a third interface in the second interface, wherein the difference between the third interface and a first interface is greater than or equal to a first threshold.
