Question

In an experiment, one selected two samples of copper-silver alloy. One sample has 40 wt% of silver and 60wt% of copper and the other has 71.9 wt% silver and 28.1wt% copper. He performed the following processes:
1). Heat the two materials to 1000oC, keep at the temperature for long enough time.
2). Drop the temperature to 850 oC and keep at this temperature for long enough time to reach to an equilibrium condition.
3). Quench the sampled by drop the temperature from 850 oC to 25 oC as quick as possible. Please help him to determine: What is the phase/s of sample one after process 1)?

Answer 1

I belive it’s 3 sorry if it’s wrong
