In-depth articles on metallurgy, materials science, and metal processing — written for engineers and learners alike.
Complete guide to grain boundaries in metals. Covers low-angle tilt/twist boundaries, high-angle boundaries, CSL boundaries, grain boundary energy, solute segregation (P, S, B, H), Hall-Petch equation, and grain refinement.
Technical guide to HSLA (high-strength low-alloy) steels. Covers Nb, V, Ti microalloying mechanisms, TMCP controlled rolling, grain refinement, and applications in linepipe and structural steels.
Complete guide to grain refinement in engineering steels. Covers the Hall-Petch equation, microalloying with Nb/V/Ti, TMCP processing, and the unique benefit of improving both strength and toughness simultaneously.
