“…In addition, the interaction of lactic acid molecules with each other is possible with the formation of both lactide and polylactide. The presence of residual furfural units in the polymer can contribute to its biodegradation [20,21].…”

The production of bioplastics based on copolymers of maleic anhydride with the addition of lactic acid and furyl alcohol is described. The obtained copolymers are promising for use as reinforcing polymer systems of cellulose-containing materials used in packaging. It has been shown that the use of lactic acid and furyl alcohol makes it possible to obtain synthetic bioplastics that are rapidly degradable in natural conditions, which is favorable for environmental protection.

This project deals with various aspects of the multilayer structure during hot package rolling in the multilayer materials with over 1000 layers, as exemplified by a multilayer structure composed of the 30HGSA and 08H18 steels. The subject of analysis was the structural state maps of steels that make up the researched structure. The results of research conducted by means of the micro X-ray spectroscopy and microdiffraction analysis establish the causes of the structural damages in the samples, which are primarily related to the ongoing flattening diffusion of the alloying elements, and serve as the basis for a model of multilayer materials recrystallization, based on a hypothesis postulating that the interlayer boundary is where new dynamic recrystallization grains form. Recommendations are given on performing hot package rolling when producing multilayer materials.

“…Recently, such type of strengthening is implemented via severe plastic deformation and subsequently reversion annealing, which main purpose is to realize the reverse PT a martensite ĺ ultra-fine-grained austenite. Such methods like equal-channel angular pressing or high-pressure torsion or cyclic channel die pressing are quite difficult to use for obtain homogeneous specimen of large sizes, so many authors tried to use more simple modifications of ordinary rolling like asymmetric [8,10], cryogenic-rolling [9] or combined mechanical processing of the surface [11] to obtain high strength. We further develop such an approach in this work using the longitudinal and cross rolling to rise the strength of austenitic steel.…”

The paper studies the regularities of the structure and texture formation in austenitic steel AISI 304 under cold rolling and subsequent heat treatment. Regularities of structure and texture formation depending on the rolling type and deformation degree were established. The ratios of main texture components, the volume fractions and the distortion of the martensite's crystalline lattice were analyzed. It is shown that mechanisms of the austenite ĺ martensite phase transformation in the course of cold rolling may change depending on various deformation schemes, as well as mechanisms of the reverse phase transformation variate under subsequent annealing. Herewith depending on the rolling type and deformation degree, the crystallographic texture formation of the nucleating austenite under the heat treatment can have single component or multi-component character and follows different orientation relations. The more scattered martensite texture after deformation results in the formation of fine-dispersed austenite, which hardens the material keeping a sufficient level of plasticity.
