A hypothetical metal has the simple cubic crystal structure shown in Figure 3.3. If its atomic weight is 86.6 g/mol and the atomic radius is 0.169 nm, compute its density.
Nitrogen is sometimes diffused into the surface of a steel component in a process called case hardening. Consider a sheet of steel (1.416x10A0) mm thick which has nitrogen atmospheres on both sides at a temperature of 1200°C. The system is permitted to achieve a steady-state diffusion condition. The diffusion coefficient for nitrogen in steel at this temperature is (6.735x10A-11) m2/s. The diffusion flux is found to be (2.52x10A-7) kg/m2-s. It is also known that the concentration of nitrogen at the...
