The steel’s flow stress depends on not only material temperature but also strain rate in uniaxial tensile tests.
Experimental methods Material The tested material was NANOHITENTM, a ferritic steel precipitation-strengthened by nanometer-sized carbides of 980MPa tensile strength.

Material structures from nature could be an inspiration to optimize the DRC coatings.
Some bio-inspired material structures for radiative cooling are developed as well.
These distributed Bragg stacks are formed from similar materials, but with layers of different effective refractive indices.

RP system integrates mechanical manufacturing, CAD, laser technology, and material science technology.
As the material used by RP system to produce work piece differs from the industrial material in actual manufacturing, it cannot be reckoned as manufacturing equipment.
During the process of modeling, the temperature of molten material has to be kept around the melting point in order for the layers of molten material to adhere properly and harden instantly.

Gjøvik Olympic Cavern Hall in Lillehammer, Norway Expression based on the local materials.
For the expression method, on the one hand, it is a method to extend and develop the traditional local materials, which reproduces the textures and colors of the traditional materials; On the other hand, it has deeply analyzed the spiritual connotation in the traditional local materials, and uses new technical method or modern materials to inherit the local characteristics.
It is preferable to select the local materials, and pay attention to inheriting and protecting the corresponding architecture technology.

Yang et al. reported that the sound absorption coefficient of rice straw-wood particle composite boards are higher than other wood-based materials in the 500-8000 Hz frequency range, which is caused by the low specific gravity of composite boards, which are more porous than other wood-based materials [6].
