In this episode, Elena and Marcus unpack "Microstructure Evolution and Microhardness of Ultrafine-grained High Carbon Steel During Multiple Laser Shock Processing", published as a Journal of Iron and Steel Research International 2015 paper. Laser shock processing (LSP): nanosecond laser pulses vaporize an absorber, confined plasma expansion drives shock waves into the surface at 10⁶–10⁷ s⁻¹ strain rates, raising hardness and fatigue strength via dislocations and compressive residual stress. Part of a series covering all 575 of Prof. Volinsky's publications, one episode at a time. Paper DOI: 10.1016/s1006-706x(15)60009-7. Note: voices in this episode are AI-generated: Elena and Marcus.

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.

In this episode, Elena and Marcus unpack "Microstructure and Mechanical Properties of Friction Stir Welded Powder Metallurgy AA2024 Alloy", published as a Journal of Central South University 2022 paper. Powder metallurgy AA2024 (Cu 4.74, Mg 1.73 wt%) made by powder mixing, cold isostatic pressing, sintering, hot extrusion (5:1 at 405°C), then T4 heat treatment; friction stir welding is the solid-state joining route because fusion welding agglomerates Al2O3 nanoparticles and degrades strength.
