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.

Initial speculation was that these streaks are resulting from recombination centers at stacking faults in the material.
In addition, no crystallographic (through selected area diffraction) or composition (through EDS) differences with surrounding material were observed.
