| Abstract | Some requirements are formulated for tool steels used to make tools with their durability being limited by strength and impact resistance rather than by wear resistance. It is shown that the high-speed steel belonging to a new hypereutectoid class is optimal for the above-mentioned application. The fracture mechanisms are considered for ledeburitic (R6M5) and hypereutectoid (11M5F) classes of tool steels. It is demonstrated that critical length crack formation in hypereutectoid steels takes place not only by means of elastic but also by means of considerable plastic deformation; on this account, the work of crack initiation in 11M5F considerably exceeds that of R6M5. The above-mentioned fact is due to the peculiarities of 11M5F steel microstructure characterized by extremely fine grain and the absence of eutectic carbides. Correlation between fracture work and deformation is established under static bending (on one hand) and impact strength (on the other hand) conditions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
