Effect of Aluminum Content on Microstructure and Properties of Fe-1.4C-1.5Cr-Alx Steel
The microstructure evolution and hardness change of Fe-1.4C-1.5Cr-Alx ultra-high carbon steel with 2%-6% aluminum content added during quenching and tempering were analyzed. It is found that the addition of Al reduces the precipitation amount of proeutectoid carbides during cooling， and helps to inh...

| description | The microstructure evolution and hardness change of Fe-1.4C-1.5Cr-Alx ultra-high carbon steel with 2%-6% aluminum content added during quenching and tempering were analyzed. It is found that the addition of Al reduces the precipitation amount of proeutectoid carbides during cooling， and helps to inhibit the formation of network carbides around grain boundaries. After adding 4% -6% Al， the tempering hardness of ultra-high carbon steel is stable between 62HRC -65HRC at 200 ℃-400 ℃， and after adding Al element， the decomposition temperature of nanoscale carbide in the tempering process of the test steel is increased， the tempering resistance stability is improved， and the martensitic decomposition temperature is increased， and the greater the amount of Al element added， the better of the tempering stability and temperature resistance of ultra-high carbon steel. |
