The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

DP steels contain islands of hard martensitic second phase in a ferritic matrix. Steel strength improves when the volume fraction of hard second phases increases. The formation of DP steels involves ...

Precipitation-hardenable (PH) stainless steels are turning up in more and more aerospace applications because they can be age hardened, sometimes after being cold worked, to various strength levels ...

Developed primarily for high-strength applications, these steels are usually heat-treated alloys that provide strengths at least equal to those of as-rolled steel. Heat-treated constructional alloy ...
