Przy pomocy wykonanego modelu urządzenia nadawczo-odbiorczego i układu przetwarzania danych przetestowano możliwość wykrywania par alkoholu o stężeniu odpowiadającym poziomowi stężenia w wydychanym powietrzu przez osoby nietrzeźwe w odpowiednich kuwetach badawczych symulujących kabinę pojazdu. Ponadto przeanalizowano możliwość i zrealizowano praktycznie wytwarzanie w sposób kontrolowany par alkoholu o zadanym stężeniu we wspomnianych obiektach.

Investigations of the developed model of the device for stand-off detection of alcohol vapours were carried out. To simulate the car cabins special glass tubes were used. Concentrations of the examined vapours in the tubes corresponded to the concentrations exhaled by a person under the influence of alcohol. To simulate appropriate concentration of the alcohol vapours a special device was built.

The microstructure and ordering of alfa-FeCo phase of the nanocrystalline Fe83 xCoxNb3B13Cu1 (x = 6, 25 or 41.5) alloys were investigated. We have stated that á-FeCo phase is atomically ordered in the Fe83 xCoxNb3B13Cu1 (x = 25 or 41.5) samples crystallized by the heat treatment in a furnace. However, after flash annealing (by current or laser) that phase is disordered. Moreover, we have found that Co concentration in the crystalline alfa-FeCo phase strongly depends on Co content in the as-quenched ribbons. The annealing conditions influence also the grain diameter of the crystalline phase. In the nanocrystalline alloys obtained by a flash annealing of the amorphous ribbons finer grains are present.

The amorphous and nanocrystalline (Fe1 xCox)85.4Zr6.8 yMyB6.8Cu1 (x = 0 or 0.1, y = 0 or 1, M = Mo, Nb or Nd) alloys were studied using Mössbauer spectroscopy. We have stated that after the low temperature annealing of the samples the decrease of the average hyperfine field due to the Invar effect was observed. This effect is associated with the increase of atom packing density after the annealing of the samples, which may lead to the noncolinear spin state in some regions. This phenomenon was completely suppressed after substitution of 10% of Fe atoms by Co atoms. At early stages of crystallization of the Fe85.4Zr6.8 yMyB6.8Cu1 (y = 0 or 1, M = Mo, Nb or Nd) alloys, the interfacial zone is poor in iron due to diffusion of Zr, B, Nb, Mo and Nd atoms outside regions where á-Fe fine grains are created. However, the iron content in the amorphous matrix is the same as in the as-quenched state. The iron concentration in the interfacial zone of the nanocrystalline alloys obtained by the accumulative annealing depends on the chemical composition of the as-quenched samples. In the nanocrystalline samples obtained by two-step annealing, the iron content in the interfacial layer is higher than in the amorphous matrix.

The microstructure of amorphous and nanocrystalline Fe42.7Co42.7Zr6.8-xNbxB6.8Cu1 (x = 0 or 1) alloys was investigated. We have stated that the nanocrystalline samples consist of the crystalline alfa-FeCo grains about 8 nm in diameter embedded in an amorphous matrix which is rich in cobalt. From Mössbauer spectroscopy studies we have found that the crystalline alfa-FeCo phase in the nanocrystalline samples obtained by the conventional annealing is atomically ordered. Moreover, the order degree depends on the annealing time. As for the samples partially crystallized during rapid quenching, the crystalline alfa-FeCo phase is atomically disordered.
