Explosive Treatment of WC-Co Alloys; Theoretical Analyses and Experimental Results

摘要

The report describes the results of theoretical and experimental investigations of the disturbance processes occurred in hard material as a result of rapidly changed effect caused by the explosive loading. This process connected with multitude complex of phenomena and depending on the loading intensity, in order to estimate stress-deformed state of materials it is necessary to choose the different mathematical models. The investigations show that the intensive shift deformations engender the problem linked with a value and proportion of normal and tangent stresses' components. This problem particularly concerns the materials treatment by the sliding front edge of the detonation wave. The above-mentioned and features of structure/property relationship of hot explosively loaded WC-Co alloys (at T=20-1200°C; P=5-20GPa) in depending of loading conditions are discussed.
