Abstract
A method can include pressing material to form a billet where the material includes aluminum and one or more metals selected from a group consisting of alkali metals, alkaline earth metals, group 12 transition metals, and basic metals having an atomic number equal to or greater than 31; extruding the billet to form extrudate; and forming a degradable component from the extrudate.
Claims15
A method comprising:
- pressing a plurality of particulate materials to form a billet, wherein the plurality of particulate materials comprises aluminum and one or more metals selected from a group consisting of alkali metals;
- alkaline earth metals;
- group 12 transition metals;
- and basic metals having an atomic number equal to or greater than 31,
- wherein at least one of the particulate materials is reactive and degradable in an aqueous solution;
- extruding the billet to form an extrudate;
- and
- forming a degradable component from the extrudate,
- wherein the extruding step comprises controlling a temperature-time profile of the extruding step by controlling a ram speed of an extruder ram during the extruding step such that incipient melting does not occur to an extent to alter surface roughness of the extrudate.
