jacobd Posted October 25, 2014 Share Posted October 25, 2014 Once upon a time I found an amazing online page where a gentleman discussed how there are many more features than hardness and toughness to a knifes edge holding ability. If I remember it was a black page with white text. It talked about how wear resistance contributed and the alloys and so on and....... Anyway it was amazing. I had it saved on my old phone, but now I can't find it. My old phone died in my toilet (don't ask). I search all the key words I could think of but still no luck. If anyone could direct to me to that page I would be grateful. I need it not at the moment for knife making but for an argument with my physics professor. Lastly I realize the immensity of the internet. Just a fleeting hope someone has seen it. Thanks guys. Link to comment Share on other sites More sharing options...
Steve Sells Posted October 25, 2014 Share Posted October 25, 2014 I am not aware of any on line resourced for titanium or copper blades and edge hoilding charts, and none for other metals even being used. Sorry. Link to comment Share on other sites More sharing options...

jacobd Posted October 25, 2014 Author Share Posted October 25, 2014 Metals was to broad, I should have said steel and it's alloys, sorry. Don't know why I didn't. Zknives might be it. Looking at it I think you might have it. Thanks! Link to comment Share on other sites More sharing options...
Steve Sells Posted October 25, 2014 Share Posted October 25, 2014 then I will relocate this, you do realize this was posted in the non ferrous section, that means Not iron ? that is akin to going into a vegan grocery and complaing you cant find T-bone steaks Link to comment Share on other sites More sharing options...
jacobd Posted October 25, 2014 Author Share Posted October 25, 2014 Did not notice. Thank you. Phone doesn't show the entire title of the forum. So I didn't connect the dots. I apologize. Link to comment Share on other sites More sharing options...
Steve Sells Posted October 25, 2014 Share Posted October 25, 2014 could that be why you have problems locating things if you cant see the screen? Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 27, 2014 Share Posted October 27, 2014 I generally pay much less for a computer than for a cell phone and the bigger screen and keyboard really help my aging eyes and fingers...My method was to have a friend who *always* had to have the latest and greatest system and then buy one a couple of generations back from him for US$100 or so. (Working in IT, there is *always* someone around who has to be at the cutting edge...) Link to comment Share on other sites More sharing options...
jacobd Posted October 27, 2014 Author Share Posted October 27, 2014 My dad is an IT guy at our local newspaper. He has an Iphone like me. I usually buy the best phone I can when I have an upgrade, with spending as little as possible. I usually get the middle phone, 16 or 32 gig, whichever it is. I have a big 27" monitor I use for a dual monitor setup, I just have to carry around and use my laptop a lot for school. So it's not set up. An android might be a better bet for the future as they tend to display full pages in a non mobile mode better from what I've seen. I was just looking for that page specifically so I can use my metallurgy handbook to look at what elements are in a certain alloy, and use the page to see what the elements main contribution is. I see alloys (in the easily accessible market) with up to maybe 1.2-1.4% carbon (02 or D2 maybe?) and lots of other alloying elements. However to see that it has molybdenum or nickel, vanadium, chromium..... Whatever, and see what it contributes is a good learning experience. I know often times bearings are 52100, and axles or PTO's are 1045 or 4140/4340 or whatever, but I wanted that page to help understand why. Like why 4140 DOM tubing is so popular for racing roll cages. Hopefully being able to see what individual elements contribute when considering their purpose will keep me from making a bad decision in the future that could put someone's well being at risk. After talking to my physics professor I have a very simple grasp of why metal loses it's magnetism at a certain temp and why it becomes malleable, as well as why cast ductile iron is more durable and hardens. It's all fascinating. I just want to dig deeper. In older posts I've seen some argue that knowing why something works the way it does as "pointless" or "extraneous", but no educated is wasted. I just don't wanna stop asking why. So any other literature recommendations would be greatly appreciated! Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 27, 2014 Share Posted October 27, 2014 sounds like it's time to start thinking about some MatSci classes! The "why's" are definitely trending toward upper level and in fact there is often arguments about them still for some things. Folks who are at the stage to think about college: NMTech's a great school and I know at least 1 prof there who's a "closet Blacksmith" (not to mention that the associated community college has classes on armor making and a fine arts metals classroom with a gas forge and treadle hammer...)

ThomasPowers Posted October 27, 2014 Share Posted October 27, 2014 Did I mention it's about 5 miles from my 1200 sq foot shop?It's not a school for the faint of heart; many folks double major as it's about 1 semester more to get a degree in math as well as in one of the engineering sciences.My Daughter attended NMT and when she graduated with a biology degree she was accepted by every Veterinary School she applied to!NMT is usually quite good about helping students out with on-campus jobs; oh yes they are justly famous for their explosives research... Small town and small college you will be associating and working with your professors and not some number in the massive crush of students in a mega-university Link to comment Share on other sites More sharing options...

ThomasPowers Posted October 27, 2014 Share Posted October 27, 2014 What and miss the middle of the night craziness a bunch of engineering students strung out on calculus, chemistry and physics get up too? (Knew one student whose student job was rattlesnake wrangler; roomed with a friend of mine and I was visiting a couple of times he got called out to do a snake pick up.) The university abuts the desert and mountains on one side. Link to comment Share on other sites More sharing options...
jacobd Posted October 27, 2014 Author Share Posted October 27, 2014 Calculus wasn't too bad. I got through it. It's when they start throwing it in physics taught by a unbelievably smart professor that assumes all these little things are a given or are assumed. That is actually why I have a habit now of having a drink when I do homework. Pass rate of my class was less than 50%. Guess which side of that percentage I was on... I get to take it again in the spring! Link to comment Share on other sites More sharing options...
rhitee93 Posted October 28, 2014 Share Posted October 28, 2014 See if the library of the school you are in has a book called "Metallurgy for the non metallurgist". It's pretty pricey to buy, but most colleges seem to either have it, or have an online version that you can read as a PDF. Then there is the ever popular ILL... http://www.asminternational.org/materials-resources/results/-/journal_content/56/10192/05306G/PUBLICATION?gclid=CI2T6bywz8ECFZc2aQodMXYAJg Link to comment Share on other sites More sharing options...

ThomasPowers Posted October 28, 2014 Share Posted October 28, 2014 sounds like you want to go higher than eutectic and start investigating secondary carbides Link to comment Share on other sites More sharing options...
jacobd Posted October 28, 2014 Author Share Posted October 28, 2014 I'm going to agree, I don't know what those are, but they sound cool. (I know a lot of pistons and connecting rods are "eutectic" or "hyper-eutectic" if the second is any different idk. Sounds like an advertising name to me) Link to comment Share on other sites More sharing options...
