A connection of particular functional parts is one of the most important design factors which determine a shape of performance parameters and efficiency.
Geometric interaction is a cause and effect of hydrodynamic properties and efficiency of the pump.
Quality of hydrodynamic pump on the market is assessed according to price and other performance factors (durability, reliability, materials used, application based on various working fluids, etc.) as well as based on its parameters and special functional properties or capabilities.
These properties are achieved by technological, design and/or hydraulic interferences to the "traditional" forms respectively procedures of hydraulic design.
In real conditions, a bend is usually located in the area of the diffuser discharge affecting the final structure of the flow.

Chemical modification of the Al-Si alloys leads to formation of fine, fibrous Al-Si eutectic mixture ensuring high mechanical properties.
They are easy to cast thanks to their good technological properties and posses acceptable mechanical properties.
However, especially during slow solidification, the silicon tends to form massive, brittle crystals, which decrease alloy’s mechanical properties [4].
These defects significantly affects alloy’s mechanical and fatigue properties.

The aim of these experiments is to carefully and precisely examine the impact of the heat treatment process on the welded joints’ physical properties and microstructure properties.
The results show that the heat treatment does enhance the mechanical properties of the material, but it is essential to conduct experiments to find the optimized parameters; or else, the properties will decrease largely.
The selection of the welding method is also one of the key factors in the success of a sound weld.
Mechanical properties of samples: (a) tensile strength, (b) hardness Design for Experiment Follow Taguchi Model To study the design for experiment for the heat treatment process for the welded samples, the Taguchi model is employed in this study.
Experimental type 3k is an experimental planning for two factors (temperature and hours) with three values: highest (+1), standard (0) and lowest (-1).

In order to evaluate the mechanical properties were performed wear and hardness tests.
Results and Discussion Dilution is a determining factor whenever one wants to assess coating properties.
Coatings mechanical properties assessed through their hardness profiles confirmed the determining role of solidification kinetics and dilution, for the current intensity levels and filler metal alloy.

The relationship between predicted fuel properties and FAME composition was investigated.
It is also reported [6] that factors such as double bond configuration influence viscosity (cis double bond configuration giving a lower viscosity than trans.) while double bond position affects viscosity less.
Thus the individual experimental complexity for biodiesel fuel properties can be reduced.

As percentage of abnormal growth increased, magnetic properties got better.
Its magnetic properties affect the energy efficiency of transformers and are closely related to the sharpness of (110)<001> texture [1].
On the other hand, many factors such as grain size, texture, volume fraction and size of precipitates in the primary annealing matrix had been shown to affect the texture development and magnetic properties of grain oriented electrical steel during secondary recrystallization annealing [5-9].
Magnetic properties were closely related to percentage of abnormal grain growth.
As percentage of abnormal growth increased, magnetic properties got better.

However, the segregation of Mg may adversely affect the performance of these materials if they are exposed to rapid heating and cooling environments such as resistance spot welding.
The formation and migration of vacancy is an important factor affecting Mg segregation.
Al-Cu, Al-Mg, and Al-Mg-Si) or impurities, high solidification shrinkage, large coefficient of thermal expansion, and a rapid drop of mechanical properties at elevated temperatures (Welding Handbook [3], Anik and Dorn [4]).
Besides the numerous vacancies, another possible factor of cracking is pipe diffusion which can be used to explain the phenomenon that cracking produced by spot welding AA5754 didn't start at a fusion line.

Introduction One of the major world tendencies in the development of engineering industry is technological development and creation of high-tech materials that able to have the necessary physical, mechanical and chemical properties and, as a rule, having a certain structure.
The basic properties of the sintered porous slide bearings [2], are determined by their functional qualities: self-lubricity, good running-in ability, wear resistance and strength.
The combined method of the process has the wide range of controllable factors, affecting on the quality level of the formed surface, and therefore, it is convenient and effective to use in the forming process of the hard-to-punch and the heterogeneous materials.

In order to optimize and increase the reliability of the experiment, the pressing pressure (P), holding pressure time (t) and the die tooling temperature (T) were taken as quantitative factors.
The effect of applied pressure on the mechanical properties of the base material and the cladding layer was determined on a longitudinal section of the obtained samples by the Vickers method (GOST 2999-75).
The presence of a brittle intermetallic layer with low plastic properties (σb=15÷17MPa) explains the low strength properties of the obtained compound.
