Aerospace Metallurgy: Los ntawm Titanium mus rau Mars Rovers

Lockheed Martin lub tshuab nqus tsev insulated cryogenic piping xa LN₂ (-196 ° C) kom shrink-fit titanium alloy Cheebtsam rau NASA's Artemis missions. Cov txheej txheem txhim kho Ti-6Al-4V grain qauv, ua tiav 1,380 MPa tensile lub zog-tseem ceeb rau lunar lander ceg sib dhos.

Automotive Shrink-Fit Innovation

Tesla lub Berlin Gigafactory siv lub tshuab nqus tsev vacuum-jacketed ducts kom txias aluminium roj teeb vaj tsev nyob ntawm 300 ° C / min, txo microcracks los ntawm 90%. BMW's 2024 lifecycle analysis qhiaVIPsystems txo CO₂ emissions los ntawm 8.5 tons ib 10,000 units los ntawm txo LN₂ pov tseg.

Nqi-Efficiency Metrics

Raws li McKinsey, Nqus insulated yeeb nkab saws txiav cov cryogen noj los ntawm 62% hauv metalworks, yielding 32/tonROI-akeydriverforemergingmarketslikeIndia's32/tonROI-akeydriverforemergingmarketslikeIndia's9B semiconductor foundry pib.
