Question

The slip system fee metals are: {110} {111} {100} All of the above, Solute solution of Ni in Cu results in: Strengthening of Cu; Softening of Cu; Increasing the ductility of Cu; Decreasing the elastic modulus of Cu. Using the Lever Rule, one can find: The percentages of the constituent phases in a binary system; The crystal structure of the unknown solid; The composition of a liquid; All of the above. Ductile to brittle transition phenomenon happens in: Fee metals; Bcc ceramics; Bcc metals; Hcp metals. Crack propagates in a brittle material, such as a ceramic; if crack-tip stress (sigma_m) exceeds a critical stress (sigma_c): if the there are small cracks in the sample; if the materials is heated; if the material is alloyed.
