← TechnologyWhich outcome predominates when brazing dissimilar metals with significantly different thermal expansion coefficients?
A)Joint failure due to residual stress✓
B)Oxidation of the lower expansion metal
C)Formation of brittle intermetallic phases
D)Increased joint ductility at high temperature
💡 Explanation
When heated, differential expansion induces stress, causing eventual cracking because stress concentrates at the interface exceeding the joint's tensile strength. Therefore joint failure happens, rather than oxidation, phases or ductility which require altering material properties besides expansion mismatch during heating.
