Oxidation of pressureless sintered Si2N2O materials.

The general materials science principles underlying the relationships between processing conditions, microstructure and the mechanical properties of the disks made by using the powder compact forging are discussed.
Therefore, TPM processes that involve plastic deformation are more capable of achieving fully densified and fully bonded PM materials with controlled microstructures such as ultrafine grains than powder compact sintering.

It is worth noting that without a good understanding of the complicated failure mechanisms and adaptive features of lightweight smart materials and structures [11, 12], it is impossible to carry out objectives oriented materials design to fulfill the requirements of high stiffness, high strength and multi-functions for lightweight smart materials and structures employed to make flight vehicles.
In this paper, the design and analysis of light-weight truss-core actuator with lattice interlayer structures and smart components involve interfacing of material science, mechanics, mechanical & electrical engineering, and computational mathematics, which leads to coordinated optimization of materials, intelligent parts and structures.

This experimental study explored the possibility of sustainable invigoration of fine waste materials in dune sand to improve the geotechnical properties.
The sands are usually fine-grained and poorly graded materials with a small amount of silt [1].
The utilization of waste materials as additives in sand improvement is more attractive to cut the carbon footprint associated with the natural material’s processing resources [6].
