PROBLEM TO BE SOLVED: To provide a method for treating a material, which comprises applying energy to a predetermined portion of the material in a controlled manner to change a local chemical property of the predetermined portion to provide a predetermined result. When the material is a shape memory material, the predetermined result is to provide additional memory to a predetermined portion of the shape memory material, or to change the pseudoelastic properties of the shape memory material. It may be. In another example, not necessarily limited to shape memory material, the process is for removing contaminants from the material to adjust the constituent concentration of the surface to form an oxide coating on the surface of the material to provide corrosion resistance. , To control surface texture, or to generate at least one additional phase grain in the material, which in turn provides a nucleation site for grain growth that can strengthen the material. ..
