Maraging steels derive their strength from the following mechanism ?
  • (A)  A fine, highly dislocated and strong martensite
  • (B)  Fine dispersions of inter-metallic of Fe, Ni, Ti etc
  • (C)  Fine dispersions of alloy carbides in a ferrite matrix
  • (D)  Fine dispersions of Fe3 C nucleated on dislocations in austenite
