A Titanium-Gold alloy (Ti3Au) has been developed that is purported to be 4 times harder than titanium, making it the hardest material known that is compatible with living tissue. Interesting stuff, primarily since I never thought that titanium and gold could bond in that manner (not that I gave it much thought), although it probably has no particular application for metal working. Still, worth a read: BBC News Article Science Advances journal where the paper is published
Hi everyone! I am currently creating a multitool similar to the Gerber Shard from an old wrench, which I suspect to be a chrome-vanadium steel. The tool features a spoon, a short prybar, bottle opener, a sharpened edge and a flathead screwdriver. Steels with chromium seem to be food-safe from what I found out online, but how about the added vanadium? The oxides at least are apparently somewhat toxic. Not knowing this, I have finished an earlier version of it a while ago from the same steel (simply the other side of the wrench), which did indeed give the food a somewhat metallic-biting aftertaste. Is this simply because I just tasted untreated metal or might this be a very light form of poisoning? Are there any common steel additives that are known to be poisonous or at least not really food-safe? Thanks in advance!
Hello, all, I have few questions: 1. Somewhere here I found, but now cannot find again, a page that talked about parts commonly found in junkyards and what types of steel they are typically made from. I am a new 'smith and this info would be real useful to me. Can anyone direct me to that page, and/or any similar pages? 2. I'm also a woodworker (Roy Underhill's books on making tools, especially woodworking tools, are what originally got me interested in blacksmithing), and I would like to try making some simple tools like a froe, chisels (especially heavier firmer and shipwright's chisels) and maybe eventually a broadaxe and other edged tools. For making very hard chisels that could be sharpened super sharp and that would hold an edge (if not be very tough), I am under the impression that I would need a tool steel with a very high carbon content. Can anyone tell me what types of things I might find in a junkyard that would have the appropriate amount of carbon (and other alloying elements) for this? 3. Alternately, should I simply buy some new A2 or O1 steel and use that instead, to eliminate some unknown variables? And if so, can anyone refer me to good, economical sources for such steel? Thanks for reading my long post and thanks in advance for any help.
