As their name suggests, Advanced High Strength Steels (AHSS) have useful tensile properties — including yield strengths in excess of 550 MPa. But these steels may require some special treatment when it comes to welding. "AHSS is sensitive to heat input," according to Adrian Elliott, a body structure researcher for Ford Motor Co. and one of the presenters at this year's Great Designs in Steel Seminar. Sponsored by the American Iron & Steel Institute, the seminar covered a collection of welding and joining technologies suitable for AHSS.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
