However, their use has been restricted due to the fact it is a recent development and many of its properties are still under investigation. This work determines the values of initial and final temperatures for the austenitic transformation and the initial and final temperatures of martensitic formation for alloy 13Cr2Ni0,1C, by means of dilatometric tests under continuous cooling. Based on these results the optimized conditions for quench and temper heat treatments were obtained. The microstructural characterization of the alloys under coarse fusion condition was carried out by optical microscopy and the presence of delta-ferrite in the martensitic matrix was observed.27-31porDilatometryQuenchStainless steelTemperdilationferriteheatingmicrostructureoil industryoptimizationpetroleumphase transitionsteelsteel structuretemperature effectEfeito da temperatura e tempo de austenitização nas transformações de fase da liga 13Cr2Ni0,1CEffect of temperature and time austenitizing in phase transformations alloy 13Cr2Ni0, 1CArtigo10.1590/S0370-44672010000100005S0370-44672010000100005Acesso aberto2-s2.0-779536718652-s2.0-77953671865.pdf
