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.

Propagation of fatigue cracks in notched specimens of EN AW 7475-T761 Jürgen Bära and Gero Wilhelmb Institute for Materials Science, Universität der Bundeswehr München, D-85577 Neubiberg, Germany ajuergen.baer@unibw.de, bgero.wilhelm@unibw.de Keywords: fatigue, crack propagation, overload, potential drop method 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.

Single-step UV Nanoimprinting Lithography with Multi-head Imprinting System and its Applications G G G JaeJong Lee 1, SeungWoo Lee 1, HyunTaek Cho1, GeeHong Kim1 and KeeBong Choi2 1Korea Institute of Machinery and Materials, Nano-mechanical Systems Research Center 2Korea Institute of Machinery and Materials, Intelligent Machine Research Center 171 Jang-dong, Yusung-ku, DaeJeon, KOREA, E-mail : jjlee@kimm.re.kr G G Keywords: Nanoimprint Lithography, Multi-head, Flexure, Overlay & alignment G Abstract.
The fundamental procedure of nanoimprint lithography is replicating the patterns defined in the stamp to any deformable materials such as photo resist spun on substrates by pressing and the physical shape of the resist is deformed during the imprinting process [1, 4].

It takes into account the total amount of luminaires as well as the optical properties of the materials in the visual task area.
It is worth to mention that the differences in the results are a consequence of the resolution setup for the calculation objects and the way each tool interprets the geometry and materials of the furniture and equipment in the room.
