Trying to learn more about titanium blades. What are advantages and disadvantages. Boker has a "sintered titanium" blade with carbide imbeded-the titan-cera zeta. anyone tried this one? only weighs 1.3 oz

This has being discussed before,but i can´t remember when.I am not a metalurgist,but i know some things about titanium anyway. First,titanium is completly stainless.Then it´s very light.Titanium is also incredibly strong and flexible. One can use it in extremly thin details,and still they are strong.
Disadvantages is that first titanium is more expencive than steel. Then it can not be hardended to more than Rockwell 47. That´s the Rockwell that Mission Knives claims is the hardest possble,without costing to mouch in the hardening procedure.

Manowar, it's spelled metallurgist and I am one. Titanium 's best attribute is corrosion resistance so as a dive knife it's perfect. It is also nonmagnetic. Hardness limits are a problem ,but the boker with added carbides would give you something like talonite. It would be interesting to compare the two.

Guys, thanks for the replies. Manowar, I am sure your English is much better than my Swedish. The ad for the Boker Titan-cera zeta says that it stays sharp much longer due to the carbides. I still don't understand what "sintered titanium" is

My English is not my strongest side,i have to admit. There are often some wrong spelled words in my posts,but i keep on learning all the time. By writing on this Forum my English has improved alot,and i have being able to meet many friendly and knowledgeable people here.
Do you speak any Swedish at all,or was it just a thougth from you(absolutely no put taken)?What i have learned from an earlier post i did along time ago,is that titanium and steel does not mix good together when it comes to laminate titanium with ordinary steels.
I don´t know either what "sintered titanium" is.
Have you visisted the Mission Knives site yet?

You can learn alot from there.
Take care/Manowar

mete,
you might want to consider double-checking his location before dissing him just because his spelling was a little off.

As far as I can tell, Titanium has two primary advantages over steel:
1) It is effectively corrosion proof
2) It is non-magnetic
While number 1 may be somewhat useful to the average user, number 2 is genuinely useful to so few people as to make it irrelevant. Unless you are one of the few people who have a reasonable expectation of encountering underwater mines or similar devices you would probably be better off with a good steel or Talonite product.
To a large extent I think the use of Ti in blades for the general public is a function of marketing rather than a genuine engineering advantage.
Titanium is percieved by many to be a premium material that is vastly superior to steel, even though in many applications it is clearly worse than steel. This is why it is frequently seen in consumer products where it offers no real advantage to traditional materials, other than allowing the manufacturer to make a lot of noise about having "Titanium technology" or some other such nonsense.
Sintered metals can be extremely strong, and in some circumstances there are material properties that can only be exploited by a sintering process. For example, automotive connecting rods and similar parts which experience very high loads are regularly sintered.

Titanium isn't very stiff, you can bend it *much* easier than a similar sized piece of steel. However it is *very* ductile and has a massive impact toughness, easily exceeding by many times to one the stainless cutlery steels.
If you don't want or need corrosion resistance, then you can find similar very high levels of toughness and ductility in the tool steels, however if corrosion resistance and a high durability is needed, Missions Ti stands out clearly over the Cobalt alloys and stainless steels.
