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.

Introduction Asphalt mixture of uniaxial compression test is an important way to evaluate performance of the pavement materials, the compressive strength will directly affect the accuracy of the design of pavement structure and material, which affects the actual performance of asphalt pavement.
Finite element method is a modern method of calculation with the rapid development of modern science and technology[1].
Finite Element Analysis of Stress-strain Data Application of ratio of diameter to height 1:1 end 2.1 numerical simulation of untreated end surface As shown in table 1, numerical simulation of nonlinear material properties uses the true stress and strain values.
By the analysis of ANSYS finite element software, the end does not handle the specimen strain data as the material model parameters, the ratio is 0.95
