· Laser intensity: The laser has to be capable of scanning many different materials, which include characteristics such as color, material finish, surface quality and surface reflectivity.
The usual value of minimum signal strength is 50 when scanning shiny materials the peak might not reach 50 so a smaller value is recommended.
The industrial partner implanted following activities: · Geometric benchmarking: suspension layout, number of parts materials used and fitment sequences were identified

(b) During
laser re-melting, the coatings of Al2O3/Cr compound materials produce analogous martensitic phase
transition, therefore, the strengthening of Al2O3/Cr compound material by laser re-melting comes
from fine-grain strengthening by Cr-alloy martensitic phase transition partly
(2) The main strengthening mechanism of metal-based compound materials is that the load is transferred to reinforcement from the substrate, and reinforcement is a primary undertaker of load, the mechanism of load transfer is a key strengthening factor.

Test Scheme
Raw Materials.
Asphalt mixtures belong to viscoelastic plastic materials, the influence of temperature on asphalt mixtures is very significant.
Asphalt viscosity was decreased with increasing temperature, the cohesion of asphalt mixture materials were also decreased, it is the main influence factor on leading to greatly reductions of anti-shear strength of asphalt mixtures.
The interlock of aggregate is the main factor of internal friction angle of asphalt mixtures, so the influence of temperature on internal friction angle φ of materials is not obvious.

Abstract.
Dynamic recrystallization during FSW was reported for both materials, stainless steel and aluminum alloys.
Stacking fault energy (SFE) of the materials can affect dislocation interactions or strength during thermo-mechanical processing.

Shrinkage and creep is the inherent properties of concrete material, and the material is developing with time [4].
In order to analyze the effects of shrinkage and creep affecting performance of concrete structure properly, the mathematical models of shrinkage and creep that can reflect the actual situation of materials should be chosen.
