How With Alloying Of Steel It Is Possible To A Achieve Properties Which Can Not Be Achieved With Heat Treatment ? |
|
Answer» A prerequisite to the hardening of steels is that martensite should be formed on cooling, but this can only be ACHIEVED if the rate of cooling is great ENOUGH to suppress the formation of pearlite or bainite and in PLAIN carbon steels this can be achieved by quenching relatively SMALL specimens A prerequisite to the hardening of steels is that martensite should be formed on cooling, but this can only be achieved if the rate of cooling is great enough to suppress the formation of pearlite or bainite and in plain carbon steels this can be achieved by quenching relatively small specimens |
