| Abstract | The microstructure and properties of a nitrogen-alloyed martensitic stainless steel in different heat treatment conditions were investigated in the present work. Hardness, compressive strength and microstructure were evaluated in the different heat treatment conditions, viz. hardening, cryo treatment and tempering. In the hardened condition, the microstructure consists of lath martensite, retained austenite, M$_{23}$C$_{6}$ carbides and MX-type carbonitrides. The typical compressive yield strength (CYS) and hardness in hardened condition were 1835 MPa and 610 VHN, respectively. After cryo treatment at −80 °C and tempering (500 °C), the hardness and CYS increased to 1936 MPa and 686 VHN, respectively. The increase in CYS and hardness is attributed to the formation of fine Mo$_{2}$C and Cr$_{2}$N particles. |

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.
