A method of joining includes bringing a bulk metallic glass (BMG) material to a temperature lower than the crystallization temperature of the BMG material and depositing the BMG material onto a first substrate with interlock surface features such that the BMG material interlocks with the interlock surface features of the substrate. The method includes joining a second substrate to the BMG material, wherein the second substrate includes interlock surface features such that the BMG material interlocks with the interlock surface features of both the first and second substrates, joining the first and second substrates together to produce a fully amorphous joint between the first and second substrates.
