Non-destructive testing of composites,nical properties and service characteristics, the level of which is considerably higher than that of traditional alloys. However, anisotropy of properties, associated with heterogeneity of components and different conditions of production, can promote fault initiation, which is extremely difficult to reveal without destruction of test samples.作者: FEAS 時間: 2025-3-22 08:59
