Annealing treatment was found to induce changes in microstructure, surface roughness, grain size and so on, indicating that with the increase of annealing temperature, the amorphous state of GST materials change first to face-centered-cubic (fcc) phase state and finally to the stable hexagonal(hex) state.
Introduction Chalcogenide phase-change materials, which refer to alloys containing at least one element of group VI [1], has gained considerable interest as a potential candidate for next decade nonvolatile memory [2,3], are widely used for data storage media.
Si wafer was used as the substrate material.

Electro discharge machining (EDM) can be used to manufacture complex shapes in high hardness materials, but the material should be conductive.
Now EDM is widely used in industry for obtaining relatively smoother surfaces at reasonable MRR and moderate cost especially with hard conductive materials [3].
Recently, many researchers studied the effect of EDM parameters on material removal rate [6] and surface quality [7], especially for hard materials, but they did not cover all the levels of EDM parameters.

Although 4D printing technologies still remain intractable, some aspects of improvement through electrospinning are possible in terms of responsive materials and self-growth materials.
Prospects of 4D Nanomaterials 4D materials contain the traditional 3 spatial dimensions and time which is the fourth dimension that affects the materials in some ways.
With respect to biomedical applications, 4D printed materials typically are divided into two types, one of which is responsive materials, and the other of which is self-growth.
Prospects of 4D nanomaterial are foreseeable in terms of its types of responsive materials and self-growth materials.
