The History of Composite Materials, from Brick to Bakelite to Biomimetic

  Video description From prehistoric materials to today’s high-tech innovations, composites have always been on the cutting edge, allowing ancient Egyptians to build shelters out of air-dried bricks and astronauts to explore space from the safety of Kevlar-infused shuttles. The rise of composites in some ways mirrors the rise of human civilization. Watch the video […]

One Minute Mentor: Heat Treatment Applied to Tool Steels

After hot forming, tool steel usually is submitted to heat treatment processes that may be split into two major steps. These are shown here in a graphical form illustrating the typical processing and heat treatment sequences, splitting them into the steps done before hardening and those done for hardening, as a function of time, temperature, and phase transformation.
