CRITERIA OF MATERIALS METAL GLASSES SELECTION FOR THERMOMETRY

In the current paper, there are considered the criteria for estimating the thermoelectric properties of metal glasses (MG) on suitability for thermometry. It is revealed that a principle of choice of thermoelectric materials based only on criteria is not quite efficient. It needs to examine also their mechanical durability, thermal, radiating, and anticorrosive properties, etc. More complete consideration proves that the use of MGs in thermometry is rather expedient.

INVESTIGATION OF INFLUENCE OF CONDITIONS OF OBTAINING PA6/MMT NANOCOMPOSITES ON THEIR THERMAL PROPERTIES

The influence of additional thermal and thermomechanical treatment of PA6/MMT nanocomposites obtained from the formic acid solution on their heat resistance and technological properties was investigated. Thermal analysis established that heating the nanocomposite to a temperature of 250 ºС and treating it on a capillary plastometer IIRT at a temperature of 230 ºС increases the degree of crystallinity and heat resistance of the samples.
