In its turn that mechanical property is associated to the work-hardening behaviour and the vast literature on this relationship is a measure of its importance.
Introduction Among the mechanical properties of structural materials, ductility is particularly important since it relates to fracture toughness and formability.
Main factors influencing ductility, and their respective origins and effects
These factors can be classified as extrinsic, since they depend on processing methods and practices
Moreover, in the particular case of SPD materials, residual stresses and dislocation locking are additional factors limiting ductility.

Parameters of Laser Welding and Their Influence of Weld Seam BALOG Peter1, a, BREZINOVÁ Janette1, b * and PASTOREK Peter2, c 1Technical University of Košice, Faculty of Mechanical Engineering, Košice, Slovakia 2Univerzity of Žilina, Faculty of Mechanical Engineering, Žilina, Slovakia apeter.balog@tuke.sk, bjanette.brezinova@tuke.sk, cpeter.pastorek@fstroj.uniza.sk Keywords: laser, welding, penetration, power, impurities.
The next important factor is focus position against a surface [1,2,3].
The quality of laser welding joints is affected by a number of factors, but primarily can be designated welding power, laser beam diameter, beam focus position, roughness and cleanliness of welded materials, the design of the weld joint, as well as used shielding gases and welding speed.

The δ-TRIP steel has attracted wide attention from researchers and industry, as it possesses the mechanical properties of the third-generation advanced automotive steels, and the lower density achieved by the addition of light element aluminum.
Nowadays, most of the research of δ-TRIP steels are focused on the heat treatment process and its mechanical properties.There are few research focusing on the deformation behavior of δ-TRIP steel at high temperature.
The peak stress (σp) affected by deformation temperature is illustrated in Fig. 2(d).
In order to exactly describe the effects of deformation temperature and strain rate during hot deformation, a temperature compensation strain-rate factor Z is usually introduced [16]

For various applications of resin materials, various mechanical properties must be considered, such as heat distortion temperature, elongation, tensile strength, impact strength, etc.
Hence, it is necessary to add other materials that enhance mechanical properties [1-2].
Therefore, how to improve their mechanical and mechanical properties (such as tribology properties) will become the focus of research.
The wear mechanism of polymer materials is quite complex, involving various influencing factors of the contact interface, including tribo-physics and tribo-chemicals.

The direction of the positive propagating is input layer-hidden layer-output layer, and the state of each layer affects only the next one.
(2) Where v is the velocity of the particle, ω is the inertia factor(linear descending), c1 and c2 are the learning factor, φ1 and φ2 are the random number between (0,1), x is the current position of the particle, pbest is the best position at present of the particle, gbest is the best position at present of the swarm.
The balance and constraint among the three parts in formula (1) determine the main properties of the PSO-BP algorithm.
Inertia factor ω is just the impact factor that the last speed of the particles affects the current one, which is mainly used to balance the global search ability and local search capabilities of the particle swarm.
(3) Where iter is the current number of iteration, itermax is the maximum number of iteration to run, ωmax and ωmin are the maximum and minimum settings of the inertia factor.

Especially, the issue of binding force between CBN composite deposit and matrix that seriously affects the cutting life is still unsettled.
Firstly, the factors influencing the electroplating technique parameters, such as the area ratio of cathode to anode, temperature, PH value, the current density of electroplating technique parameter, stirring role and current of commutation were reasonably selected [1].
The equal height of the CBN abrasives in composite deposit is affected by abrasives size, order of planting abrasives and unevenness of matrix.
It suggested that cubic nitrogen had not flake off from the composite deposit and had extraordinarily great wear-resisting property.

The interaction albumin/surfactant with detergency properties was evaluated by pH and viscosity measurements.
The foam was produced by mechanical stirring.
Scaffolds utilized for simultaneous tissue support and delivery of specific factors must exhibit an appropriate pore structure, release kinetics, and suitable resorption rates [3].
Considering that different synergy can affect the foam volume, the use of additives, such as albumin, in the presence of a surfactant with detergency property, improves the foam action due to the albumin adsorption in the films surface which stabilizes the foam [6, 7].
The use of 0.3 wt.% dispersant optimized the suspensions with 68 wt. % solids percentage, resulting in adjusted properties in the foam production

Microstructures, Properties and Fracture Behavior of Solidified TiC-TiB2 Composites with increasing content of TiB2 Xuegang Huanga, Long Zhang, Zhongmin Zhaob and Chuanzeng Pan Mechanical Engineering College, Shijiazhuang 050003, China aemei127@126.com, bzhaozm2007@yahoo.cn Keywords: TiC-TiB2 composite; rapid solidification; fine-grained microstructure; fracture behavior Abstract.
Introduction TiC-TiB2 composites are considered potential candidates for engineering applications under extreme conditions due to their excellent combination of mechanical and electrical properties as well as their good corrosion and oxidation resistance at high temperatures [1].
Because combustion characteristic in high-gravity field similar to thermal explosive not only makes the gas escape rapidly, but also forms the thermal vacuum around the liquid products, the key factor affecting the densification of the ceramic is considered the shrinkage cavities due to rapid solidification of TiC and TiB2 crystal.
