It is shown that with an increase in temperature, load, and holding time, the volume fraction of pores decreases, and the fraction of fiber increases, which leads to an increase in the composite strength. In all cases, the shape of the fracture surface indicates the brittle nature of the composite fracture.

Investigation of the effect of compacting mode parameters of a carbon-aluminum wire preform on the strength of the produced compact

It is shown that with an increase in temperature, load, and holding time, the volume fraction of pores decreases, and the fraction of fiber increases, which leads to an increase in the composite strength.

The value of the nitrogen compositional stability coefficient has been determined for the alloys of the Fe-Cr-Mn-Mo-N system obtained by self-propagating synthesis, namely, aluminothermy under nitrogen pressure. The obtained results permit to predict the maximum possible content of nitrogen in continuous ingots (without bubbles and gas porosity in the volume) and, consequently, the structural-phase composition of alloy and optimal regimes of alloying.

New two-dimensional structure - diamane have been studied by molecular dynamics simulation. The stiffness constants are calculated from molecular dynamics and then applied to analize Young's modulus, shear modulus, and Poisson's ratio.

As cast Al-1.8Mn-1.6Cu-0.15Cr-0.15Fe (wt. %) alloy structure consist of aluminum solid solution, eutectic Al6(FeMn) and Al2Cu, as well as Al7Cr and Al20Cu2Mn3 dispersive particles. Radial shear rolling results in partial dissolution of Al20Cu2Mn3 dispersoids, grain refinement to the size of 1.6 μm, increasing yield stress up to 83 MPa and ultimate strength up to 216 MPa. The plasticity of the deformed alloy is 25%.
