Time-dependent Reliability Model with strength degeneration When the lifetime or the loading numbers N is stochastic variable and the probability density function is , the probability density function of fatigue lifetime n under the deterministic constant amplitude cyclic load s can be acquired by material fatigue strength experiments.
The yield strength of material is 290MPa.

Experiment methods Materials of sample and laser cladding.
Therewith the material's yield of the 1 # sample is bigger, so the material has softening phenomenon [4].
But this material's ability of deformation and hardening is strong.

New materials and gowns are being developed, fitting the level of the barrier function with the comfort issues and therefore the selection of the most suitable gown is vital.
Three types of surgical gowns were studied: • Single-use simple gown - Fig.1a • Single-use reinforced gown - Fig.1b • Reusable gown - Fig.1c Fig. 1 a) Single-use simple gown; b) Single-use reinforced gown; c) Reusable gown Tested Materials.
The material used for the reinforcement at the forearms is from the same material as the rest of the gown, but with a higher mass per surface area (75 g/m2).
In human sciences, the unit of thermal insulation used is the Clo.

The material in consideration is a well-known and well-studied alloy, particularly in terms of the possibilities for using it in thermal treatment processes.
Moreover, selecting the chemical composition of Mg and Si content in the AlMgSi alloy should lead to improved consolidation of the material.

The microstructure of the obtained material has been characterized by means of SEM and XRD.
The material properties are taken as such: below 700°C, the material remains a powder, between 700−1605°C the material is in a solid phase, at 1605−1655°C the material is solid plus a liquid mushy zone, and above 1655ºC the material is in its liquid phase.
The material properties were taken from [9].
