Abstract.
Its entering length have close relations with some factors such as surface conditions, welding variables and agitation force[3].
Therefore, these influence factors in the junction line entering are seriously considered in order to obtain reasonable solutions.

Properties of Bulk Amorphous Iron Based Alloys
The lack of crystallinity leads in case of iron based alloys to a remarkable ensemble of
mechanical and magnetic properties.
The mechanical properties of the amorphous iron based alloys differ from the properties of crystalline alloys.
This fact affects negative the soft magnetic properties of the alloys.
Mechanical properties.
Compressive strength and hardness were measured for evaluating the mechanical properties.

The chemical composition and monotonic tensile properties are shown in Table 1 and 2 [8].
Conclusions The effect of TiN film prepared by dynamic ion mixing process on fatigue properties of high strength stainless steel was investigated by using 4-point bending fatigue test
(2) In a range of stress intensity factor KImax < 20 MPa·m1/2, the deposition of TiN film accelerated the fatigue crack propagation rate. in a range of KImax > 20 MPa·m1/2, the TiN film hardly affected the crack propagate rate

Mechanical properties especially impact toughness values were increased due to significant reduction in the tool wear.
The peak of temperature of stir zone is major factor which decides the phase transformation and subsequent properties of the joints.
This has significant effect on the tool life of developed tools and subsequent properties of the weld quality.
Further study is required on the correlation of metallurgical characterization and mechanical properties of induction heat assisted frictions stir welding of stainless steels.

The results indicate that plasma sintered porous BCP bioceramics have better mechanical
properties and may also have better biological properties.
Maintenance of porous structure may be one of the affecting factors in ceramic-induced osteogenesis [5].
If the sintering parameters are optimized, the mechanical properties can increase with increasing sintered densities.
The results indicate that plasma sintered porous BCP bioceramics have better mechanical properties and may also have better biological properties.
The surface of samples that underwent a simulated inflammation procedure is smoother and the amount of bone-like apatite formed on them is less than that formed on samples immersed in normal SBF all the time, which may indicate that the light acid in an inflammation response would be one of the factors affecting the bone reconstruction when Ca-P bioceramics implanted in living body.
