Dissimilar metal joining /

This volume discusses dissimilar metal joining by fusion and solid-state processes. It is a complex process due to differences in chemical compositions, physical properties, mechanical properties, and thermal properties of the parent metals to be joined. The contents focus on issues related to fusio...
