Heng Aode explains the use of metal phase diagrams
The metal phase diagram is characterized by its intuitiveness and integrity. It can be seen from the phase diagram that the state of the system is at a certain temperature when the pressure is constant, and the composition of each phase of the equilibrium coexistence, what is the relationship between the quantities of each phase? Relationships, and the direction and extent to which phase changes occur when external conditions change. Therefore, the drawing of metal phase diagrams is of great significance for understanding the relationship between the composition, structure and properties of metals.
Experimental methods for drawing phase diagrams generally use various physical and chemical methods, such as visual inspection, thermogravimetry, differential thermal analysis, and the like. In addition, other experimental techniques such as metallographic microscopy and X-ray diffraction can also be used.
A floating shelf is a form of shelf with its wall fixings hidden within the shelf board, with no visible supporting brackets. It can be supported on hidden rods or bars that have been attached to studs. A thick floating shelf may be made of a hollow-core shelf glued to a cleat.
A floating shelf may have two or more channels open from the back towards, but without reaching, the front, into which slide fasteners attached to the wall, typically held in place by screws inserted through the bottom of the shelf.
For typical floating shelf supports, a supplier suggests that floating brackets with a diameter of 12mm can support a shelf at least 22mm thick loaded with 20kg, and 18mm brackets can support 30kg on a 28mm shelf.
This description is in reference to one particular type of floating shelf support, others options are available. Also not to be confused with corner shelves, which would require entirely different supports to make them "float".
Floating shelves are a good fit for a contemporary minimalist style interior.They can be used to expand storage space, atop a radiator to double as storage, or inside a hallway to double as a console table.
