Introduction
Aluminum alloys are structural materials of choice for manufacturing components suitable for
aerospace and automotive applications due to favorable properties such as low density, good
corrosion resistance, relatively low costs of production and the abundance of the material supply.
The advantages of liquid forging are the ability to reduce materials scrap associated with die casting processes from gatings and risers, and very importantly, being able to form components from wrought aluminum alloys, otherwise formed only predominately by forging, extrusion and machining.
Experimental Procedures Al alloy Al-6061 (Al, 1%Mg, 0.5% Si) ingots were used as the material for liquid forging.

However, variables involved in composite structural design possess much higher variability than
those of metal case due to uncertainties in material properties, geometric size and manufacturing
process of composite materials [1].

Introduction
At present, tungsten metal material production is the main method used in powder metallurgy tungsten powder or alloy powder compaction, sintering.
Differential thermal analysis method is at the same temperature to be measured in the system and the reference material to a certain speed heating or cooling, curve recording system tested and does not change the temperature difference between the base material and time.
When the tested system with phase change, because there are endothermic or exothermic reaction, then measured reference material system and reference temperature difference will change, so as to obtain the differential thermal curve reaction endothermic or exothermic Gu Huofeng, according to the curve to determine the phase transition temperature.

Abstract
The influence of single overloads on the fatigue crack initiation and propagation of an EN AW 7475-T761 alloy was investigated using SEN-specimens.
Experimental details The experiments were undertaken with SEN-specimens of an AW7475-T761 clad sheet material.
The thickness of the sheet material was 2.88 mm, including 80 µm clad (AW 7072).
The SEN-specimens with a length of 80 mm and a width of 12 mm were machined from the sheet material.
