Waveguides formed by heavy ions implantation show an unique advantages: the beam dose can be 1-3 order lower than that of light ion implantation and it can reduce the fabrication cost significantly.
In order to obtain satisfactory engineering properties for the duplex stainless steels, long period stop at the embrittlement temperature range should be avoided during production and fabrication.
