Steel is real - again
A new process for heat treating steel produces a product with a higher
strength to weight ratio than aluminum or titanium. As an added bonus, it can be welded without any need for post-welding heat treating. www.flashbainite.com Discuss... |

Here too: http://www.gizmag.com/flash-bainite-...testing/40774/ with further links from there. Sounds like it's got real potential. I didn't read details on its weldability, but they seem to claim it's very good. I don't know if that applies to the sub-millimeter wall thicknesses we might use. The ductility at that strength level is amazing. I can envision radically hydroformed steel tubes that are thin and light. Of course, I'm not so much into losing grams from a bike; but it's still pretty fascinating. And it's cool that it was developed by a hacker, so to speak, instead of a certified research metallurgist. -- - Frank Krygowski |

"Bainite", which is a description of the structure of steel, was discovered in 1920 and, if what I read is correct, results in a steel that is 7% stronger. -- cheers, John B. |

And it's cool that it was developed by a hacker, so to speak, instead of a certified research metallurgist. I did come across a study that was largely concerned with weldability and apparently this material is weldable and perhaps produces stronger welds then some other steels. Much of the literature I find seems to be published by those who are trying to sell the new idea but there do seem to be claims that it increases strengths of steel by 7% although I can't find any comparative studies of specific alloys. A 7% increase in strength of, say 1020 steel compared with ???? for 4130, for example. -- cheers, John B. |

Well, you can look it up for yourself, but from what I read it was first described by E. S. Davenport and Edgar Bain in the early 1920's. Who, I believe, both worked for U.S. Steel. Bain died nearly 20 years ago. "in the 1920s Davenport and Bain discovered a new steel microstructure which they provisionally called martensite-troostite, due to it being intermediate between the already known low-temperature martensite phase and what was then known as troostite (now fine-pearlite). This microstructure was subsequently named bainite by Bain's colleagues at the United States Steel Corporation although it took some time for the name to be taken up by the scientific community with books as late as 1947 failing to mention bainite by name." -- cheers, John B. |
