The microstructure,hardness and impact toughness of as-cast or quenched Fe-C-B-Ti alloy containing 0.67%~1.82% of Ti were studied.The results show that the microstructures of the as-cast Fe-C-B-Ti alloys containing 0.67% of Ti consist of martensite,pearlite and reticular eutectic boride with high hardness and impact toughness.With the increase of titanium content,the martensite of the as-cast Fe-C-B-Ti alloy gradually disappears,and ferrite appears,which results in gradual decrease of hardness and impact toughness.After heat treatment,the reticular eutectic borides of the alloys are broken,and grow coarser noticeably with the increase of temperature.As the quenching temperature arises,the hardness and impact toughness of the Fe-C-B-Ti alloy increase,and achieve maximum value at 1 050℃ while they decrease over 1 050℃.
