Many lead-free solders have been studied as replacements for Sn37Pb solders, and among them Sn-3.0Ag-0.5Cu, Sn-0.7Cu, Sn-9Zn and 64Sn-35Bi-1Ag solders are the most promising candidates owing to their overall properties, including mechanical properties, wettability, reflow properties and reliability [2], etc.
However, the properties of these lead-free alloys in corrosive environments has not been widely reported, though it is of importance in many automotive, aerospace, maritime and defence applications.
The order affecting corrosion of SC solder is Zn>Bi.
So the synthesized result showed that the sequence in In, Bi, Zn affecting on corrosion of SC solder was that Zn>In>Bi.

According to range analysis, the sequence of factors including the individual factors and interaction factors that we obtained is PP, SP, PP×CP, CP, CP×SP, PP×SP, CP×PP×SP.
But the other two factors affecting the change impact on tap for life hasn’t been considered.
Proved that cryogenic treatment improved the mechanical property of HHS greatly[6-8].
Since three factors all influence the HSS tap life, and various combination of three kinds of factor led to different HSS tap life, it is necessary to ensure the effects sequence of factors, including the factors and interaction effects of factors.
There were three factors are considered in the test, so the number of the factors was 3.

The factors that affect the hammer head wear are the following: material of hammer head, manufacture quality, structure design, rotor rotational speed, condition of material input, and the gap between head and grate bar, etc.
The key factors are material of hammer head, manufacture quality and structure design.
The manufacturing defects, such as shrinkage cavity, crack and transcrystalline crack, will worsen the mechanical properties and even cause fracture of the hammer head.
Different structure and geometry of the hammer head differ in heat treatment on mechanical properties and inner metallographic structure, which affect the wear resistance, especially to those thicker and bigger head.
The best way is to optimization design the hammer head without changing the impact kinetic energy and strength, which will improve the Utilization rate of the head, reduce the impact of heat treatment on mechanical properties and avoid decreasing the wear resistance of the hammer head.

The Cu/Ta nanofilamentary wires containing N=853 Ta nanofilaments exhibit better mechanical properties than the Cu/Nb ones but not as encouraging as initially expected.
Mechanical properties of Cu/X nanocomposite conductors versus the conductor diameter d.
Nevertheless, Cu/Nb/Cu wires exhibit more encouraging mechanical properties (for example, compare b2 and c3 conductors).
The prevention of central bursts appears even more complex in composites materials since further factors, like the billet structure and material characteristics, increase the number of elaboration conditions leading to defects.
On the contrary, in Cu/Nb/Cu wires the co-cylindrical structure is kept and mechanical properties appear better than Cu/Ta ones, themselves better than Cu/Nb ones.

It is shown that a mechanical joining of aluminum and glass is possible.
The limiting factor is the strength of the glass, which is breaking during the tensile tests.
Only the aluminum sheet is affected by the shock wave pressure.
Because the glass substrate is the limiting factor of this connection during the tensile tests.

Our proposed discrete element method is as follows: , (1) , where: mass of elements (mm); t – time (с); і – spherical element index; linear velocity vector; moment of inertia; external factors (force) affecting the elements i through the interaction of contacts with elements j; k – the total number of spheres that interact with each other with elements і; external torque, which is directly connected through the interaction of the contacts of the spherical elements і and j; falling moment (top to bottom).

Formation material is benefits to improve resin’s properties such as infiltration ration, thermal conductivity and anti-creep property, meanwhile increase the dispersion of CNTs.
Experiments selected foam Ni as matrix via CVD method prepared foam Ni/CNTs and expected CNTs will deposited around the foam Ni’s surface more adequate without any effect of the foam Ni’s original properties.
Its dimension at nanometer and highly aspect ration in axial tensile strength besides the signal wall CNTs properties are more outstanding [2].
Consider these factors the catalyst PH value should be controlled in 7-8 and pyrolysis temperature unfavorable exceed 650℃

When the characteristic size diminishes from macro to micro level, the volume reducing factor is more than 106 times to the surface reducing factor.
From the above analysis, it is known that the MEMS fuze mechanism is quite different from the traditional fuze mechanism in the aspects of processing technology, material property, structure form and “micro size effect”, which are the basic factors leading to the reliability problems of MEMS mechanism with large difference from traditional mechanism.
Environment stress is the important factor inducing MEMS mechanism failure.
Surface corrosion may change the property of material surface such as roughness and surface force etc, which affect the function of MEMS fuze mechanism seriously.
Different from the steady performance of body structural material, the property of electroforming material may be affected by many factors such as temperature of electroforming liquid, pH value and current density etc.
