Budget Titanium

Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode! In this episode, Elena and Marcus unpack "High-Carbon Ferrochrome Effects on Microstructure and Mechanical Properties of Powder Metallurgy Titanium Alloys", published as a Journal of Materials Engineering and Performance 2019 paper. Motivation: titanium is expensive (reactive melt needs special equipment; poor machinability, ~10% material utilization); powder metallurgy (ball mill 2 h, cold press 700 MPa, sinter 1573 K 1 h in vacuum) avoids melting entirely and is near-net-shape. Part of a series covering all 575 of Prof. Volinsky's publications, one episode at a time. Paper DOI: 10.1007/s11665-019-04282-x. Note: voices in this episode are AI-generated: Elena and Marcus.
