Second amorphous alloy application I have seen from Heraeus. The first one was last year in creating ZR based BMG.

Why all of a sudden?

Translated the first paragraph:

"The invention relates to a method for producing a component from an at least partially amorphous metal alloy comprising the steps of:
Providing a powder of an at least partially amorphous metal alloy;
Forming a shaped semifinished product from the powder by the powder is applied in layers and the powder particles of each newly applied layer are fused at least at the surface of the forming semi-finished product by targeted local heat input and / or melted and joined together at the back cooling; and
Hot pressing of the semi-finished product, wherein the hot pressing is effected at a temperature which is between the glass transition temperature and the crystallization temperature of the amorphous phase of the metal alloy, wherein a mechanical pressure to the semifinished product is exercised during hot pressing, and the semi-finished product is compressed during the hot pressing.

The invention also relates to a component produced using such a method from a powder composed of an at least partially amorphous metal alloy and the use of such a component as a gear wheel, friction wheel, wear-resistant component, housings, watch case, part of a transmission or semi-finished product."
