The R-phase is a phase found in nitinol, a shape-memory alloy.It is a martensitic phase in nature, but is not the martensite that is responsible for the shape memory and superelastic effect.
In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water.
Latent heat storage can be achieved through changes in the state of matter from liquid→solid, solid→liquid, solid→gas and liquid→gas. However, only solid→liquid and liquid→solid phase changes are practical for PCMs.
After completion, they may attend three years of high school (Sekolah Menengah Atas or SMA). Some high schools offer an accelerated learning program so students who perform well can complete their level in two years.
