摘要: Abstract This paper attempts to investigate the role of strain in fracture low strength steel temperature range −196 28°C and at crack tip rate 10 −5 10°/sec. The tensile test data is suitably processed estimate toughness specimen. micro-fractographic observations help identify microfracture mechanisms relate them with governing criteria. Even for non-microvoid coalescence mode alloys region −140 −77°C, a significant plastic identified. significance critical zone discussed it has been compared process fracture.
