We have calculated and experimentally measured the amplitudes of shock waves generated in the monocrystals of the nickel alloy KhN57KVYu under the action of powerful nanosecond laser pulses. We employed an electron-microscope method to study the defe

1. Laser heat treatment (both with and without fusion of the surface) of KhN59KVMTYu and KhN63KVMTYu heat-resistant aging alloys may change the dispersion of the structure in surface layers up to 1 mm thick and more. 2. In laser heat treatment with f

1. The phenomenon of "early overaging" is not observed in single crystals, i. e., softening of the alloy does not begin until a particle size is reached that is almost an order higher than the "critical" size for polycrystalline material. The phenome

1. Pronounced rebuilding of the crystal structure occurs at a sufficiently great depth during the cutting of heat-resistant alloy ZhS6KP as a result of the simultaneous action of loading and temperature: coalescence or reverse solution of the γ′-p

1. In alloys with moderate amounts of γ′ phase (KhN67MVTYu and KhN60MVTYu) with particle sizes of 350–700 A the combination of high strength and ductility is due to the mechanism of particles being cut by individual moving superdislocations. The

In the structure of the WC and Co phases making up VK20K hard metal the presence was discovered, in the as-sintered condition, of dislocations and twins, which may be attributed to the generation, during the postsintering cooling of the alloy, of lar

1. The second stage of creep in heat-resistant nickel alloys is due to changes in their intercrystalline structure. 2. With the same creep rate during the entire second period, which is characteristic of heat-resistant alloys containing a moderate am
