TI  - Effect of Multi-Element Microalloying on the Structure and Properties of High 
      Chromium Cast Iron.

AB  - High chromium cast iron (HCCI) has been widely used as wear-resistant material in 
      the industry. Alloying is an effective way to improve the microstructure and 
      mechanical properties of HCCI. This paper added multi-component V-Fe-Ti-Nb-C-Zr-B 
      alloy (VFC) to HCCI, showing a significant synergistic solution-strengthening 
      effect. The results show that the added V-Ti-Nb-B are dissolved in M(7)C(3) 
      carbide to form the (Cr, Fe, V, Ti, Nb)(7)(C, B)(3) alloy carbide, and a small 
      amount of V and all Zr are dissolved in austenite and martensite. Adding VFC into 
      HCCI improved the hardenability of HCCI, decreased the residual austenite content 
      from 6.0 wt% to 0.9 wt%, increased the martensite content from 70.7 wt% to 82.5 
      wt%, and changed the structure and content of M(7)C(3) carbide. These changes 
      increased the hardness of as-cast and heat-tread HCCI by 1.4% and 4.1%, increased 
      the hardness of austenite and martensite by 7.9% and 7.0%, increased the impact 
      toughness by 16.9%, and decreased the friction coefficient and wear loss by 2.3 % 
      and 7.0 %, respectively. Thus, the hardness, toughness, wear resistance, and 
      friction resistance of HCCI alloy are improved simultaneously.
