... on joint design. When perfectly clean surfaces are brought into intimate contact, interatomic bonds form a joint. Bond strength is greatest when the mating metals are mutually soluble, but good bonds can be obtained with dissimilar, not otherwise weldable metals and with highly differing thicknesses. When...

.... With reference to Fig. 3.9 , it should be noted that even if a thin-walled die-cast part may contain more casting defects than an optimally cast permanent mold casting, the die-cast part will show superior properties due to the finer grain size. As the wall thickness increases, the advantage of die casting...
