摘要:

The diffusion of59Fe and185W in powder-metallurgical swaged tungsten samples was investigatged by autroadiographic method in the temperature range of 1300–1900 °C. The results proved that in the case of185W only surface diffusion and in the case of59Fe both, surface and grain-boundarg diffusion exist.
