I hope you are already trying GRX-810 for your combustion chambers. And you can make your own NbTaTiHf! 25X better fracture toughness than 304L! The Nb45Ta25Ti15Hf15 refractory high-entropy alloy (RHEA) was fabricated by arc melting Nb (99.95% metals basis excluding Ta), Ta (99.95% metals basis), Ti (99.95% metals basis), and 5 Hf (99.9% metals basis, excluding Zr) slugs, pieces, and wire together. The feedstock materials were purchased from Alfa Aesar (Thermo Fisher Scientific, Tewksbury, MA 01876 USA). Before melting the feedstock, they were ultrasonic cleaned for 10 minutes in an isopropyl alcohol bath. The alloy ingots were arc melted in a water-cooled copper crucible under an inert Ar atmosphere. Each alloy ingot was flipped and remelted 5 times, without opening the vacuum chamber to 10 homogenize the composition. To avoid pick-up of interstitial elements during the arc melting process, the vacuum chamber was backfilled with commercial grade argon (99.995% Ar) after achieving a vacuum of 10-5 torr. Finally, before melting the feedstock materials, a Ti Getter was melted for 2 minutes to further minimize residual gases in the chamber. The as-cast Nb45Ta25Ti15Hf15 RHEA ingots were then cold rolled into billets with ~30% reduction in thickness 15 to a final thickness of ~8 mm. The cold rolling procedure was performed in the Metals Processing Lab located at the Air Force Research Laboratory's Materials and Manufacturing Directorate; this facility is operated through an onsite contract with Materials Resources LLC. The rolled billets were then cleaned and polished using 320 grits SiC paper, and annealed at 1373 K for 1 hour in a 20 stainless steel bag in air and subsequently quenched in room temperature water. https://lnkd.in/gAgti7CE

Doing fault diagnostic with Insight on Cummins N14 engine.

engine diagnostics and a regen on a jlg 1500ajp. improvement on standard maintenance.

HAPPY MONDAY!!! Here is another wonderful ABB ACH580 Drives Technical Tip of the day from our own Tim Skell. Thank you, Tim! Did you know that our ABB ACH580 logs the most recent faults that may occur in an ABB drive? This is a great feature for troubleshooting which allows you to find out through diagnostics regarding what/why exactly an ABB drive would stop working or having issues. Check out our "Diagnostics" and then select "Faults and Event Log" to learn more today. And remember, any parameters that you may modify should always be followed up with a parameter back up. #abbdrives #abbmotion #abbmotors #abbmotionservices #vfds #vsds #variablefrequencydrives #variablespeeddrives #hvacr #hvac #hvacmaintenance #hvacservice #boilers #pumps #pumpsolutions #fans #blowers #ACH580 #BorieDavis #mechanicalengineering #mechanicalcontractors #vfdhelp

NOTICE! By every means, always determine the cause of an engine shutdown. Make necessary repairs before attempting to restart the engine. #engine #genset #equipment

KMS series is three-phase motor reversing module with ratings from 25 to 40 Amps at operating voltages ranging from 24 to 530 VAC. This product is ideally suited for three phase motor reversing control, such as the electric actuator.

In the realm of engine maintenance, DEF fluids have a rich history of being utilized primarily in truck engines. However, in a more contemporary context, their utilization has extended to include smaller engines as well. Employing DEF serves as a strategic means of adhering to the rigorous standards set forth by the EPA, all while ensuring that engine performance and fuel efficiency remain uncompromised.
