Nickel-based superalloys are used in hot gas path components in gas turbines due to their excellent creep resistance. To achieve their maximum mechanical capability, these materials must be cast as single crystals. However, prior to funding research into the development of castable, single-crystal nickel-based superalloys, the industry typically utilized conventionally cast or directionally solidified blades.
This video shows a part being built up layer by layer using SPEE3D’s high-speed metal 3D printing technology, a process that is 100 to 1000 times faster than traditional 3D metal printing.
The way we process metals strongly influences their mechanical properties. This video explains how to use approaches such as alloying, strain hardening, and precipitation hardening to strengthen a metal by modifying its microstructure.
Lawrence Berkeley National Laboratory, Berkeley, Calif., has discovered a new and practical path toward manufacturing titanium with high ductile strength. The technique relies on low-temperature cryoforging to create nanotwinned titanium, which has 30% more ductility than normal titanium.
Blasting abrasives include angular chilled iron grit, alumina, crushed flint, crushed garnet, silicon carbide, and crushed slag.
