Diamalloy 2002 alloy
Diamalloy 2002 alloy is a special alloy composed of tungsten carbide and nickel based alloy, which is usually used as a powder for special spraying processes (such as HVOF: supersonic flame spraying process). In order to optimize the processing technology of these powders, it is necessary to know the melting and solidification properties of the materials. The figure shows the temperature rise and fall test results of this material. The melting behavior begins at 966 ° C and spans nearly 300K throughout the entire melting process. After 1265 ° C, the material completely melts. The solidification phenomenon in the cooling curve occurs at 1261 ° C. Due to the complex composition of this alloy and the complicated processes of melting and solidification, it can be easily handled by selecting the appropriate DSC instrument.
Melting of Bronze Alloy (CuSn)
Bronze alloy is a copper based alloy that has been used as weapons, containers, or other metal products since ancient times. Today, it is often made into bearings and spring components. The melting behavior of the alloy will change depending on the content of tin and the proportion of additives in the alloy. The alloy sample in the picture is used in the infiltration process. The sample undergoes a solid-phase phase transition within the range of 521 ° C and 568 ° C (starting point). Melting occurs at 777 ° C, with the entire melting range spanning over 200K, and the sample completely melts after 994 ° C.

Phase transition of metallic iron
This data is from DSC 404 F3 Pegasus equipped with a rhodium furnace body ® The experimental temperature was obtained from room temperature to 1620 ° C. The peak appearing at 770 ° C is caused by a change in the magnetic properties of the material (Curie transition). The peaks at 926 ° C and 1399 ° C are caused by the crystal transformation of the material. Perhaps due to the presence of impurities in the sample, the obtained data differs slightly from the literature values. Melting occurs at 1534 ° C, with a melting heat of 266.1J/g, and a deviation of 1.5% from the literature value of pure iron

Specific heat test of silicon carbide
Silicon carbide has applications in many fields, including in filtering devices for automotive exhaust systems in steel companies, as well as in heating elements for clutches and high-temperature furnaces. The figure shows the specific heat test data of silicon carbide in the range of room temperature to 1200 ° C. The increasing trend of specific heat of silicon carbide in the figure conforms to the Debye principle, and the specific heat at high temperatures shows a weak temperature dependence, following the Duron Petit law.

Phosphate glass powder - glass transition, structural transition, specific heat
A sample of phosphate glass powder with very fine particle size was tested in the temperature range of room temperature to 1100 ° C. The measured glass transition temperature (midpoint) is 483 ° C, which is typical for this type of glass material. An exothermic effect was detected at 632 ° C, which may be caused by structural changes within the material and/or agglomeration of powder particles above the softening point. Due to the shrinkage of the surface area of the powder, a small amount of energy is released. In the temperature range of 600 ° C to 900 ° C, this exothermic effect overlaps with the specific heat change effect.
