| dc.description | Two indig~nous steel, NST 37-2 and NST 60Mn were sruJi~d ro detem1ine rhe effect of various heat treannent!: on c.'leir hardness. Resulrs indicate lha! warer seems to be m•l>t efficient quenching medium where maximum hardne$s is rcquin:d. Howel'er, when: har\iness can be sacrificed, mineral oil can be used for qucn.;hing. NST 60Mn SLC:el, wilh higher manganese and carbon contents sbowed greater hardness at fast cooling rate. This grearer hardness was due to the greater amount of mancnsitic rransfonnation and precipitation hardening of carbides (Fe3C)._ Tbe air-cooled samples did nor sh'"' much increase in hardness ·because, !he stee-ls transfoml more imo ferrit~ and \'tl)' lirrJc of pearlire. The lechnologi;:~l importance of rhe results obuined in relation to Nigerian Stmcrural Adjusuncnl Programme (SAP} are discussed. | |
