Multi step processing method for the fabrication of complex articles made of metallic glasses
In one embodiment, the invention provides a process for thermoplastic forming of a metallic glass. For example, in one embodiment, the invention provides a process for thermoplastic forming of a metallic glass ribbons having a thickness of between about 50 to about 200 microns. Related articles of manufacture and processes for customizing articles in accordance with the process as described herein are also provided.
Aluminum-copper-lithium alloy product for a lower wing skin element with improved properties
The invention relates to a method for manufacturing a laminated or forged material, the thickness of which is 14 to 100 mm. The materials according to the invention are particularly suitable for manufacturing airplane underwing elements.
Mechanically tuned rapid discharge forming of metallic glasses
A mechanically tuned rapid capacitive discharge forming apparatus and methods that utilize compliant and shock absorbing components in electrode assemblies in order to accommodate the stresses and strains of the thermally-expanding feedstock and maintain continuous electrical contact between the electrodes and the feedstock throughout the duration of the electrical discharge.
METHODS FOR PRODUCING FORGED PRODUCTS AND OTHER WORKED PRODUCTS
Generally, the present disclosure is directed various embodiments to additively manufacture AM preforms to reduce, prevent, and/or eliminate defects that occur in post processing operations (e.g. forging, shot peening, machining, or other post processing operations).

FEEDBACK-ASSISTED RAPID DISCHARGE HEATING AND FORMING OF METALLIC GLASSES
The disclosure is directed to an apparatus comprising feedback-assisted control of the heating process in rapid discharge heating and forming of metallic glass articles.
Three dimensional decoration method
A method of decorating an element. This method includes the steps of: taking the element (1, 11, 21, 31), the element including anchoring (7) for improving the securing of the decoration (5) to the element; making a mask (4) of the desired thickness of the decorations (5), and having at least one opening (4); placing the at least one opening in the mask (4) against the place to be decorated so as to form at least one mold (4, 6, 6, 6, 100); filling the at least one mold with an at least partially amorphous material via hot forming; and removing the mask (4).
HIGHLY ALLOYED STAINLESS STEEL FORGINGS MADE WITHOUT SOLUTION ANNEAL
The post forging solution anneal step normally carried out on hot forgings made from highly alloyed metals can be eliminated while still avoiding the formation of deleterious intermetallic phases by adopting a number separate features in connection the way the forging is made.

Closed-die forging method and method of manufacturing forged article
Provided are: a closed-die forging method capable of preventing a temperature decrease in a to-be-forged member during forging, easy temperature monitoring during forging, and filling the cavity end portions of a die with the to-be-forged member; and a method of manufacturing a forged article using the closed-die forging method. The closed-die forging method includes covering a surface of the to-be-forged member (preferably a super-alloy) that contacts the lower die with a metal heat-insulation member (preferably stainless steel) prior to forging, except for at least a part of the surface that contacts an upper die during forging, placing the heated to-be-forged member on a lower die, and hammer-forging the to-be-forged member integrally with the metal heat-insulation member. A forged article is prepared by heat-treating the forged article obtained by the closed-die forging method (preferably in a disk shape) at temperatures not lower than the recrystallization temperature of the forged article.
