The equation provided with the sin 1/2 136 seems to have unusual bracketing. The 136 im assuming has units of degrees, therefore would it not need to be encompassed by the sin term? thus sin (136/2) degrees? 129.78.64.106 06:53, 6 September 2006 (UTC)

Would anyone be able to find some sample Vickers hardness values for typical materials?

Added Stainless steel, Carbon steel and iron. Pity i couldnt find them with the same load value User A1 04:58, 12 September 2006 (UTC)

[edit] Chapter 22 instead of 23

Considering the index of Smithells Metals Reference Book I assume that the values mentioned are not in chapter 23 (sintered materials) but in 22 (mechanical properties of metals and alloys). I'll check this afternoon if my conclusion is right. 130.161.144.96 11:11, 22 June 2007 (UTC)

I found the values in an online database, as my library didn't have it in hard copy. If you have the book that would be a better source. Thanks User A1 13:17, 22 June 2007 (UTC)
