Abstract: Methods for processing machining chips comprising aluminum-lithium alloys are provided. The method comprises cleaning machining chips comprising an aluminum-lithium alloy to remove at least a portion of processing fluid from the machining chips and providing cleaned machining chips. The method also comprises compressing a volume of the cleaned chips to provide a compact comprising a density of at least 70% of the full theoretical density of the aluminum-lithium alloy.
