Compare precipitation hardening (Sections 11.10 and 11.11) and the hardening of steel by quenching and tempering (Sections 11.5, 11.6, and 11.8) with regard to the following: (a) The total heat treatment procedure (b) The microstructures that develop (c) How the mechanical properties change during the several heat treatment stages

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
