brittleness and hardness of metals
I wonder how can I present in Engineering Data a brittleness and hardness of metal.
1. For example grey casting. I know that I can take it from the library but I can not see a Vikers hardenss.
2. How to present very hard and thin a nitrided metal surface ?
3. How to present a rebars which is soft and plastic in inside and very hard on the surface?
Thanks in advance
