MBN 305 Phase Diagrams & Transformations 2018-2019 Spring Semester: 108 108 178 178 MBN 305 Course Description: MBN 305 will provide the basic principles of phase equilibria and phase transformations in general and help students to adapt into this technologically important area. The course will focus mainly on the underlying thermodynamic principles of phase equilibrium, transformation and state. The binary and ternary phase diagrams, kinetics of phase diagrams, diffusion mechanism, and both the diffusional and diffusionless transformations in solids will be discussed.

Thermodynamics International System of Units (SI): The seven base units in the International System of Units Length: metre (m) Mass: kilogram (kg) Time: second (s) Electric current: amper (A) Temperature: kelvin (K) Luminous Intensity: candela (cd) Amount: mol (mol)
Thermodynamics "When you measure what you are speaking about and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge about it is of a meagre and unsatisfactory kind." William Thomson (Lord Kelvin) Secondary Variables and Units (SI): velocity Horsepower (hp)? acceleration force F energy power 1 m 1 m t 1s
Newtonian Mechanics Equilibrium: state in which no spontaneous changes are observed with respect to time. Mechanical Equilibrium:? Question A mass of m is initially at rest and is dropped from a height of y o above the ground. Neglecting the drag forces, find the time for this mass to reach the ground? g = 9.81 m/s 2. 1642 1726 Isaac Newton Question A mass of m is initially at rest and is dropped from a height of y o above the ground. Taking into account the drag forces, find the time for this mass to reach the ground? g = 9.81 m/s 2.
