One Minute Mentor: Martensitic Stainless Steels
A stainless martensitic alloy should have the following characteristics:
• It must have at least 10.5% chromium to qualify as stainless, and even more for better corrosion resistance.
• It should be fully austenitic at some temperature.
• The temperature at which austenite forms on heating should be sufficiently high to permit tempering above the temper embrittlement range.
How water moves glass
Scientists at the Science Center Straubing base new sensoric materials on petrified pine cones.
Lead paint test uses molecular gel recipe (with video)
The prototype test makes it easy to see whether a paint chip contains more than the regulated 5000 parts per million of the poisonous metal that was banned from pigments in 1978.
Graphene goes into silicon at room temperature
Materials researchers at North Carolina State University, Raleigh, developed a technique that allows the integration of graphene, graphene oxide (GO), and reduced graphene oxide (rGO) onto silicon substrates at room temperature by using nanosecond pulsed laser annealing.
