After the abovementioned process the alloy was reheated to 7

After the abovementioned process, the alloy was reheated to 700 degree C and held for 10^5 s. The final microstructure is A. 100% A B. 100% Spheroidite C. 100% P D. 100% Tempered M A hypothetical eutectic phase diagram for metals A and B is shown on the right. The approximate composition range for precipitation hardening of A-B alloys is A. between 2% and 18.3% B B. Between 0% and 2% B C. between 2% and 61.9% B D. between 18.3% and 61.9% B

Solution

Solution 14

After the above mentioned process ,the alloy was reheated to 700c and held for 10^5 s. The final microstructure is   B. 100% Spheroidite

Solution 15

Approximate composition range for precipitation hardening of A-B alloy is between 18.3% -61.9% B
