Answer
a) Quenched and tempered at T = 425 degrees Celsius to maximize yield strength
b) Quenched and tempered at T = 650 degrees Celsius to maximize ductility
Work Step by Step
Refer to table A-21
Look for AISI 1060
Find out for what value of temperature and method of treatment does the material has highest yield strength
Similarly, find out for what value of temperature and method of treatment does the material has highest elongation i.e. maximum ductility
