Notes:
The purpose of this study is to evaluate the effect of the stages and temperingtemperatures in the microstructure, tenacity and hardness of the vacuum sintered high speed steelAISI T15. The material was uniaxial pressing at 700 MPa and sintered in a vacuum furnace at1275ºC. After that, different samples of the materials were submitted to the annealing treatment at870ºC, quenching at 1235ºC and tempering (single, double and triple) at 540, 550 and 560ºC.Concluded the treatments, Rockwell C measurements of hardness were accomplished and, toevaluate the toughness of the material, TRS (Transverse Rupture Strength) tests were done. Lateron, the materials were submitted to the metallographic preparation for microstructure analysis inoptical microscopy, SEM, EDX and X-ray diffraction. Finally, each property analyzed wasevaluated and correlated with the different tempering stages and temperatures accomplished
