A Joining Dissimilar Material Pairs by Mechanical Locking Method (MLM)
(International Journal of Precision Engineering and Manufacturing, 2021)
Several methods that have been used in joining material pairs with diferent properties share many disadvantages. To overcome these disadvantages, the current study introduces mechanical locking method (MLM), which is a new ...
