Sintering affects the density as well as the mechanical properties of the sintered parts.
These factors can affect the microstructure, pore size and shape, density and porosity of the samples.
These, in turn, influence the mechanical properties of the samples after the sintering process.
There are many sintering parameters that can affect the mechanical and physical properties of titanium alloy foam.
The density can affect the mechanical properties of the samples.

Results showed that when the manufacturing parameters are: time of 47min, pressure of 19MPa and temperature of 156°C, the composites have higher mechanical properties.
The mechanical properties increase with increasing of pressure.
The composites have largest difference between the maximum and minimum of mechanical properties under time and pressure, so time and pressure are main factors affecting mechanical properties of composites.
The mechanical properties increased with increasing of pressure

Treating time at 650 °C was a main factor determining microstructures and properties of the composites.
Mechanical tests were performed on the materials with different microstructures to establish their properties and fracture behavior.
These factors increase the cost of component production and make the application of these composites economically unattractive.
Mechanical tests were performed on the Ti-(Al3Ti+Al) and Ti-Al3Ti composites to compare their mechanical properties.
Table 2 summarizes the mechanical properties of the laminated composites.

The influences of sintering conditions on microstructure and mechanical properties were studied.
Because of the similar green porosity of the three samples, the linear shrinkage and weight loss are two main factors determining the porosity of the sintered samples.
The interlocking microstructure is in favor of enhancing the mechanical properties.
Such microstructure is detrimental to the mechanical properties.
The morphologies of the sintered samples determine the mechanical properties.

It is suggested that, the presence of plasma flow in plasma MIG welding process refines the microstructure at HAZ area, thus improves the mechanical property at the area.
Meanwhile, the mechanical property at the weld zone has evaluated by using Vicker microhardness testing.
The microhardness test then has been carried out in order to evaluate the mechanical property at HAZ.
The refinement of microstructure at HAZ is suggested to improve the mechanical properties at the area.

Test and Analysis of Shengma Pure Yarn and Shengma/Modal Blended Yarn Mechanical Property Yang Qing-bin1,a 1College of Textile and apparel, Qingdao University, Shandong, Qingdao 266071,China aqdbrian@163.com Key words: Shengma Fiber, Blended Ratio, Yarn Property，Twist Factor，Elongation，Yarn Abstract: To discuss yarn mechanics property of shengma pure yarn or shengma modal blended yarn with different twist factor and different blending ratio were spun, yarn properties were analyzed.
The quality of the product, yield, cost, and the handling property were affected by the twist.
Different kinds of fibers have different twist factors. 18.2tex pure Shengma fiber yarns with different twist factors were spun.

Dissimilar Friction Stir Welds in AA 5086–AA 2024: The Effect of Process Parameters on Microstructures and Mechanical Properties S.
The effect of tool traverse and rotation speeds on the microstructures and mechanical properties are quantified for welds between non-age-hardening Al5083 and age hardening Al2024 and compared to single alloy joints made from each of the two constituents.
It was found that the weld properties were dominated by the thermal input rather than the mechanical deformation by the tool.
The effects of variations of traverse and rotation speed on the mechanical and microstructure properties of joint are investigated.
These factors are the main factors which affect the heat input.
