Joining different material with different properties is a challenge.
The main considerations for controlling this process are weld current, weld time, weld force, properties of materials, especially the jointed material, surface condition and others.
The study began with run #1 until run #9 with various different factors as listed in Table 2.
The setting parameters for Run #9 are the factors of A3, B3, and C2 that is shown in Table 2.

Introduction Cold formed and precipitation hardened aluminium alloys are of great interest in the automotive and in the aircraft industry due to their favourable mechanical properties in combination with a low specific weight.
The local heating results in inhomogeneous recrystallisation processes and at least in a strong loss of the initial mechanical properties.
As different welding processes like metal arc welding, tungsten inert gas welding or beam welding processes generate rather different softening zones, these zones may act like structural notches due to the locally varying material properties.
The term metallurgical notch refers to the abrupt changing of mechanical properties in the environment of the weld seam as a result of the applied heat treatment. [1] In use, this distribution of mechanical properties can create complex strain and stress conditions.
While the welded naturally hard samples behave like the base material, welded samples made of the alloys EN AW 6082 could not reach the mechanical properties of the base material.

Effects of the Microstructure and Mechanical Properties for Wear Resistant Casting Surface with Vacuum Evaporable Pattern Casting Infiltration Process Dachun Yang 1Faculty of Mechanical Engineering, Huaiyin Institute of Technology, Huaian, Jiangsu 223003, China adachuny@163.com Keywords: high boron steel casting, wear-resistant composite layer, lost foam casting, vacuum evaporable pattern casting (V-EPC) infiltration process Abstract.
Introduction In practice, the casting surface is required with some special properties in many cases, such as wear-resistance, corrosion-resistance, etc.
This way may change microstructures of the casting surface and improve its mechanical properties due to interaction of the molten metal and ceramic particles.
As further investigation on material preparation and mechanical properties, it was used to research and develop composite materials of the casting surface [3].
Carbon content of the high boron steel casting also is another important element which determines its mechanical properties.

Based on applying efficiency function in finding the property of each flatness actuator, a new method is developed to describe a mill's comprehensive ability of flatness control.
And we found the factors which contribute to whether a mill can weaken a certain flatness error.
It indicates that |σ| is affected by another two factors: severity of the initial error (|σini|), and similarity between σini and Eff.
Based on using efficiency function in finding the property of each actuator, a mill's comprehensive ability depends on the set of the difference between one actuator and others.
Furthermore, whether a flatness error can be eliminated is determined by three factors: the severity of the error, the strength of the mill's ability, and the similarity between them.

The residual stress significantly affects the fracture behavior of the pipe.
The pipe with bending work has effects on the piping properties due to changes in shape and residual stress, so the properties of the pipe with bending work will have big difference with base material.
The properties of materials such as yield strength, tensile strength of pipe used in this study were obtained from studies by Kim and others, and the results are as Table 1.
The properties of copper piping used for the finite element analysis are the general copper with the elastic modulus 125Gpa and Poisson’s ratio 0.33.
The properties of elastic area used in analysis used properties of general copper, and as data of plastic area, acquired true stress-true strain curve was used from the studies by Kim and others [3].

The precipitation of these phases increases the strength of the Ti-6Al-4V alloy and, consequently, enhances the mechanical properties.
THT aims to enhance mechanical properties by a microstructure development being unattainable by conventional heat treatment [1].
The chemical composition and the mechanical properties of the alloy Ti-6Al-4V were inspected in this study and illustrated in Table 1 and Table 2 respectively.
As a result, the strength of Ti-6Al-4V increases and its mechanical properties is improved.
The mechanisms relevant for the success of THT of Ti-6Al-4V depend on several factors.

Melting characteristics of the feedstock under sole influence of heat are considered, covering a wide range of microstructural and microchemical factors, believed to be of importance at high temperatures.
The generation of the thixotropic slurry within the injection molding system and its solidification behaviour are accompanied by detailed features of the molded structures and their correlation with properties of net-shape components.
An important factor which also affects this application is shape.
The high integrity structures, with fine grains, generated after nearliquidus molding, result in properties superiour to conventional casting and to other methods of semisolid molding (Fig. 3).
These factors are vital for semisolid processing since it operates at certain solid content and does not allow for the compensation of potential heat losses using melt overheating.
