Verification work was performed, in which detailed illustrated answers were given for 5 tasks according to the copper-zinc system state diagram
1. Show the liquidus line and the solidus line
2. Describe the system phase
3. To determine the type of nonvariant transformations
4. For alloys
I - 25% Zn
II - 40% Zn
III - 70% Zn
construct cooling curves and determine the nature of phase and structural transformations
5. In alloy II, at a temperature of 600 ° C, determine the phase composition, the chemical composition of each phase and their proportion
