The researach performed within the scope of this topic involved a large number of experiments, including tensile and bending tests, hardness and toughness, as well as metallography and fractography tests, in order to determine the mechanical properties of the materials and the welded joints in detail, along with their microstructures and their influence on the obtained test results.
These values correspond to the parent material, since fracture occurred in it (as expected).
While ANSYS offers numerous benefits in terms of fatigue crack growth simulation, it does not have the ability to allow crack growth through different materials (both in terms of mechanical properties and Paris coefficients), thus it was necessary to come up with an alternative way of achieving this goal.

The mechanism by which the outer minimum hardness region is produced is not clear but may be due to re-solution of GP zones or recovery of cold work (in T3 materials).

Introduction The metal foams as a type of new materials have attracted growing interests since about fifteen years ago in many fields of research [1,2].
These materials combined with low mass and important mechanical characteristics have useful applications in many fields.

At the Department of Materials Science and Engineering of USP-EEL a process was developed for the production of a low cost mixed yttrium-rare earth oxide, RE2O3, where RE stands for rare earth elements, starting from "Xenotime", an yttrium rich phosphatic ore (RE,Y)PO4[3].
The type and amount of this secondary phase is responsible to a high degree for the observed creep behaviors of these materials.

The property parameters of four damping materials is shown in table 1 under this condition.
The loss factor and elastic modulus of QZD damping materials are lower.
Constrained layer usually chooses a high elastic modulus and small quality materials, thus, the authors chose Al6061 as the constrained layer material, whose material performance parameters are shown in table 2.

Surface heat treatment with laser beam experienced self-quenching that cooled rapidly into materials without cooling agent.
Materials with high thermal conductivity properties produced a thick laser modified layer due to ease of heat penetration into the substrate [9].

Introduction Synthesis and properties of one-dimensional nanostructured materials is one of the most important areas in modern materials science and technology.
Therefore, the dielectric constant of nanostructured materials should be larger than that of the conventional materials.
In nanophase materials, the grain boundaries have an amorphous or glassy structure.
