A new additive manufacturing process, termed "friction freeform fabrication," has been recently proposed by the authors. One of the unique capabilities of the process is that it can facilitate fabrication of three-dimensional parts in materials that are difficult to fusion deposit. The current study is a striking demonstration of this, in which cylindrical samples of 40 mm height and 10 mm diameter were successfully produced in borated stainless steel ASTM 304B4, a material known to be very difficult to fusion weld or deposit. Microstructures and mechanical properties of these samples were investigated in detail and were compared to those of standard wrought-processed alloy 304B4 Grade B material. © 2013 ASM International.
