Nanoparticles vs. Fatigue

Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode! Episode 156 of the Professor Alex Volinsky podcast. In 50CrVA spring steel, thermodynamics decides whether Ti/V/N/C precipitate above the liquidus as micron inclusions or below it as nanoparticles — and fatigue life drops ~10x across that size change (208–242k vs 43–63.5k cycles). Engineer the precipitation window, engineer fatigue life. Published title used ("Multiple Microelements' Coupling Behavior"); corpus wording differs. Based on the paper: Thermodynamics Analysis of Multiple Microelements' Coupling Behavior in High Fatigue Resistance 50CrVA Spring Steel with Nanoparticles; Y. Wang, L. Fu, M. Zhou, Z. Zhou, X. Pang, S. Zhong, A.A. Volinsky; Materials, 2019, Vol. 12, article 2952. Hosts Elena and Marcus. AI-generated voices.
