The process factors such as the sintering temperature, the sintering time, the heating rate, the compaction density, the compaction methods, and the alloy system, would affect the sintering densification of TiH2 powders and TiH2-Al-V alloy powder.
If the parameters of sintering are controlled properly, the physical and mechanical properties of material could satisfy the requirement.
The properties of dehydrogenation were studied.
The results of properties of compacts sintered at different conditions are shown in Table 5.
The results show that the density and densification of compacts are influenced by some factors involving temperature, the system of alloy, the density of compacts.

Introduction Compressive test is one of the most difficult mechanical tests on composite materials.
It seems that matrix properties plays more dominant role in determining the compressive strengths, compared to the fiber arrangements.
Matrix properties play more important role in determining compressive strengths.

The mechanical properties of the strip rolled from roll-cast strip were almost as same as that of the strip made from cast ingot.
The microstructure becomes fine by rapid solidification, and the mechanical properties can be improved.
There are some factors which affect on the sticking.
The mechanical properties of the roll-cast strip are almost the same as that of the strip made from ingot.
It is said that the mechanical properties of the roll-cast strip are inferior to that of the strip made from ingot.

Then how can the gradient structures affect the fatigue behaviors?
Generally, the fatigue crack initiation affected by many factors in polycrystalline materials.
So the influencing factors of fatigue crack initiation may be the dislocations accumulation and its interactions with grain boundaries.
Then how the gradient structures affect the fatigue behaviors?

Thermal modeling is essential for understanding and optimizing the FSW process, since the final properties of the weld depend on the temperature to which the material has been exposed [5].
Conclusions · The mathematical equations for the influencing factors in the modeled system and the terms involved in the finite element numerical model were established

The results of the physical-mechanical and permeability properties of the functional textiles indicate a promising increase in abrasion resistance by at least 70%, although some other properties deteriorate.
This research was conducted as a preliminary investigation [8] to determine the most suitable shapes of 3D-printed polymers on textiles that provide adequate protection against impact without significantly affecting the useful properties of textiles, such as excessive weight, compromised flexibility, and deterioration of permeability properties.
Table 3 and Table 4 show the measured values of the physical mechanical properties of selected woven fabrics used as substrates for 3D printing.
The adhesion of 3D printed objects to textiles is influenced by many factors, of which the structure of the fabric is one of the most important.
The measured physical-mechanical properties and permeability of the functional fabrics showed that 3D printing of thermoplastic polymers on the fabric increased abrasion resistance, but compromised some other fabric properties.

In conclusion, the response of unbonded flexible pipes are both related to its own structural properties and external loads.Coupling factors of different conditions should also be considered.
It is necessary to study the mechanical properties of unbonded flexible pipes.
(a) (b) Fig.1.Typical structure of unboned flexible pipe Mechanical model In order to consider various factors, individual and combined modeling methods were adopted in this paper.
External pressure directly affects the friction between adjacent layers, and thereby have greater effects on the pipe’s bending properties than internal pressure.
It should be noted that the coupling factors should be taken into consideration during overall assessment.

They found atomic particle size is the main factors of the diffusion reaction from 40ms to 160ms.
PVdF fiber membranes have a good absorption properties and good mechanical strength because it has three-dimensional network structure.
However, due to the increasing flexibility of high-polymerized polymer chain under high temperature, mechanical properties go bad in service.
Furthermore, the tensile strength of the polymer mechanical properties added significantly to 160% with 5% wt of the filler added.
This new approach of embedded and insulated hybrid nanofillers could help to develop a new generation of polymer nanocomposite electrolytes with high ion conductivity and improved mechanical properties.
