| Abstract: | The heat treating processes and mechanical properties of a new die materialDT-40 made of steel bonded carbide,are investigated.Experimental results show that thiskind of alloy is easy to be heat treated to a large extent,resulting in extremely high hardness(over 68 HRC)and tempering resistence comparing to the material with bonded-phase steelmatrix.It is also found that there is a linear relationship between the compressive yieldstress and Rockwell hardness in DT-40.The service life of stamping die made of DT-40 cangreatly be lengthened. |
