Question

If metallic systems A and B are having solidification temperature range (STR) of 25°C and 150°C respectively, then

1.  A will have higher solidification cracking tendency

2  B will have higher solidification cracking tendency

 3. Both will have similar solidification cracking tendency

4.  B has better weldability than A considering solidification cracking tendency

​

Answer 1

b

will have higher solidification cracking tendency

Answer 2

If metallic systems A and B are having solidification temperature range (STR) of 25°C and 150°C respectively, then out of A having higher solidification cracking tendency, B having higher solidification cracking tendency, both having similar solidification cracking tendency and B having better weldability than A considering solidification cracking tendency, the correct statement will be that both will have similar solidification cracking tendency as it does not depend on temperature.
