As such alloys may exhibit the rheological behaviour required for semisolid forming and the excellent final mechanical properties of Al-Zn alloys, we investigated the thermodynamic aspects of the solid-liquid transition of Al-5.5wt%Si-5wt%Zn alloy, the morphological stability of this alloy in the semisolid temperature range and the corresponding rheological behaviour.
As Al-Si-Zn ternary alloys may exhibit the rheological behaviour required for semisolid forming and the excellent final mechanical properties of Al-Zn alloys, we investigated the thermodynamics of the solid-liquid transition of Al-5wt%Si-5wt%Zn alloy (referred to here as Al5Si5Zn), the morphological stability of this alloy in the semisolid range and the corresponding rheological behaviour [5].
Grain size and globule size (a) and roundness shape factor (b) as a function of heat-treatment holding time.
However, long holding times adversely affect process control and the commercial viability of SSM processing.
The authors hope to further investigate the potential of Al5Si5Zn by measuring its mechanical properties and fatigue resistance after appropriate heat treatment.

A Box–Behnken design(BBD), one of RSM with three levels (3 factors and 3 levels) was employed to investigate the effects of ultrasonic time, ratio of water to raw material and ultrasonic power on the extraction yield of polysaccharides from Melaleuca ahemifolia.
These three factors were designated as X1, X2 and X3 and prescribed into three levels, coded +1, 0 and −1 for high, intermediate and low values, respectively.
Xi and Xj are the levels of the independent variables that represent the linear, quadratic and cross-product effects of the X1, X2 and X3 factors on the response, respectively.
Meanwhile, the ultrasonic power (X3) was the major factor affecting the yield of polysaccharides.The lack of fit measures the failure of the model to represent the data in the experimental domain at points which are not included in the regression.

Rapid production of useful parts that can withstand harsh environments, like high mechanical loads and temperatures, is made possible by this technology.
Numerous variables affect ambient temperature, including the glass transition temperature (Tg) of the polymers used to make the filament and the surrounding environment[5].Polymer characteristics are greatly impacted by ambient temperature, especially when it comes to glass transition temperature (Tg) because it denotes the change from brittle to ductile states, the Tg is a crucial parameter that affects the mechanical behavior and stability of polymeric materials.
The influence of metal's reflective and conductive properties on maintaining consistent ambient temperatures and their impact on print quality using temperature-sensitive materials like ABS remains underexplored.
Furthermore, the effects of metal’s thermal conductivity and reflective properties on maintaining a stable ambient temperature particularly when working with heat-sensitive filaments like ABS have not been thoroughly explored.
This trend reflects the influence of environmental factors such as air draught and natural convection, which prevent a stable thermal environment from being maintained.

Their properties affect the final steel surface quality and its response to further processing.
Controlling the oxide layer growth kinetics and mechanical properties can make pickling easier and improve downstream behaviour.
Its properties, depending on the steel chemistry and the process conditions, have an important impact on the final surface quality.
Hot strip users' requirements on scale properties are particularly strict to warrant material good response to subsequent processing steps like pickling, stamping, laser cutting or direct coating.
Obviously enough, thickness is a determinant factor of tertiary scale properties, as temperature and time also are, because oxidation rate increases exponentially with time [2].

Fully consider equipment comprehensive influence factor, introduce the main factors affecting the weight vector, on the basis of comparing the group benefit values,  the optimization result is got.
If more influence factors are calculated, the calculation process is more complex.

Secondly, according to application requirements, the initial compact structure of fabric must be determined, such as fabric texture, tightness and cover factor etc., otherwise fabric cannot be manufactured.
After the successful weaving fabric will form a certain appearance, by which the surface structure is affected.
There are many properties related to fabric thickness, such as tenacity, warmth retension, permeability, wind resistance, stiffness and draping property.
Because of the different application, differences of fabric properties are required, and structure decides property, so diversity and differences of fabric structure are resulted in.

Grain refinement can greatly enhance the material mechanics, magnetism and other physical properties.
Grain size has a significant effect on the performance of the material, especially on mechanical properties.

The film condensation exists in the steam-water heat exchanger widely and affects the effective heat transfer in some degree.
Relationship between surface free energy and heat exchange property It is generally accepted that an unbalanced force filed exists on the surface when the resultant of the internal forces within the molecules of the solid material is zero.
The heat exchange surfaces prepared by these materials are of better fouling prevention and heat exchange properties than the common copper pipe, which have been used in a power plant of Shandong province and can be widely applied in many industries such as chemistry, electric power and pharmacy.
