1. For aluminum reinforced with steel fibers, increasing the fiber concentration to 50–60 vol. % produces only a small increase in the electrical resistivity of the composite. At higher fiber concentrations the rate of ascent of theϱ vs Vf curve s

1. An analytical expression has been derived describing the compression of a sandwich-type reinforced material during hot pressing with allowance for the flattening of the matrix protrusions extruded into the gaps between the fibers. 2. Experiments c

1. A model is proposed with the aid of which it is possible to calculate the energy expended in the dynamic densification of sandwich type reinforced materials. 2. It is shown that the energy supplied in dynamic hot pressing is expended in driving th

1. On the basis of an analysis of a model, an equation has been derived for calculating the work of densification in the DHP of reinforced materials as a function of the plasticity properties of their matrices and the geometric parameters of the comp

1. A study was made of the effects of temperature (over the range 200–1000°K) and composition (at fiber contents of up to 35 vol.%) upon the TEC's of aluminum-and titanium-base composite materials reinforced with uniaxially aligned high-strength s
