Researchers use eggshells to make stronger, lighter metal alloys

Researchers have developed a technique that uses powdered eggshells to produce high-quality magnesium alloys for automotive, aerospace and biomedical applications. The approach offers a low-cost, more sustainable alternative to conventional calcium materials, which require energy-intensive processing from ore. “For example, calcium carbonate and calcium oxide are important materials for manufacturing metal alloys,” says Bharat Gwalani, […]

One Minute Mentor: Tempering of Shock-Resisting Tool Steels

Both the tungsten and silicon types of shock-resisting tool steel resist softening during tempering to a greater degree than carbon tool steels. Secondary hardening does not occur in these steels, except to a minimal degree in some high-W or high-Mo compositions (e.g., S5 and S7). The effect of tempering temperature on the hardness of various […]
