TI  - The Effect of the Pre-Existing VC on the Evolution of Precipitate and Mechanical 
      Properties in the H13 Steel.

AB  - To further improve the mechanical properties of H13 steel at room and high 
      temperatures, its precipitates were regulated based on the Thermo-Calc results. 
      Scanning electron microscope (SEM), electron backscattering diffraction (EBSD), 
      transmission electron microscope (TEM), and X-ray diffraction (XRD) Rietveld 
      refinement were used to study the effect of the intercritical annealing on the 
      microstructure and mechanical properties of H13 steel. The results show that the 
      intercritical annealing at 850~95  degrees C increased the VC volume fraction from 2.23 
      to 3.03~3.48%. Increasing the VC volume fraction could inhibit the M(7)C(3) 
      precipitation from 10.01 to 6.63~5.72% during tempering. A large amount of VC 
      also promoted the M(23)C(6) precipitation during tempering at higher dislocation 
      densities. The intercortical annealing simultaneously increased the elongation of 
      H13 steel. An excellent combination (room temperature: ultimate tensile strength 
      (UTS) of 898 MPa and total elongation (TEL) of 19.35%, 650  degrees C: UTS of 439 MPa, 
      and TEL of 27.80%) could be obtained when intercritical annealing is performed at 
      900  degrees C. Meanwhile, after aging at 650  degrees C for 128 h, the room temperature UTS and 
      TEL decreased by only 31 MPa and 0.52%, respectively.
