The procedure for tests of contact creep in ring bearing-samples is developed and also a generalized diagram of residual stresses formation after babbitting and machining a babbit layer in bearings is obtained. It is shown that the existence of a cyclic deformation of an antifriction layer results in a complete relaxation of the sum of all constant constituents of residual stresses. It is concluded that the main reason of the dissi-pation of strength characteristics in babbit samples consists in rheological properties of this material.

Processing Properties

The results of investigating the rheological properties and processing characteristics of a system consisting of 60 wt% epoxy bisphenol A resin of type ED-20 and 40 wt% phosphazene-containing epoxy oligomer are given. The kinetic dependences of the shrinkage, residual stresses, and rheokinetics are obtained, and the gelation times, activation energy of viscous flow, and glass transition temperature are determined.

Compound Tial

In order to improve the mechanical properties of an intermetal1ic compound TiAl, a composite material of TiAl involving a second phase Ti2AIN was prepared by a new combustion reaction method. It is found that Ti2AIN (hexagonal structure) is a rod shape as shown in Fig.1 and its side surface is almost parallel to the basal plane, and this composite material has distinguished strength at elevated temperature and considerable toughness at room temperature comparing with TiAl single phase material. Since the property of the interface of composite materials has strong influences to their mechanical properties, the structure of the interface of intermetallic compound and nitride on the areas corresponding to 2, 3 and 4 as shown in Fig.1 was investigated using high resolution electron microscopy and image processing.

And Chemical Properties

The addition of fibres or particles (TiB2, SiC etc.) into TiAl intermetallic alloys could increase their toughness without compromising their good high temperature mechanical and chemical properties. This paper briefly discribes the microstructure developed by a TiAl/TiB2 composite material fabricated with the XD™ process and forged at 960°C.The specimens for transmission electron microscopy (TEM) were prepared in the usual way (i.e. diamond polishing and argon ion beam thinning) and examined on a JEOL 4000EX for microstucture and on a Philips 400T equipped with a SiLi detector for microanalyses.The matrix was predominantly γ (TiAl with L10 structure) and α2(TisAl with DO 19 structure) phases with various morphologies shown in figure 1.
