查询词典 high iron

The drawing testing、cutting testing and fracture analysis of high chromium casting iron－carbon steel's compounding interface showed: the compounding interface has higher strength and the impact toughness of composite plate is about 5 times of high chromium casting iron, which make it possible to make full use of high chromium casting iron's excellent wear resistance in practice under the high impactive condition.

需要特别指出的是：复合板的冲击韧性高铬铸铁5倍以上，这为高铬铸铁在高冲击工况发挥其优异耐磨性能提供了可能。采用试验方法生产的双金属复合板件正在矿山冲击较大的工况下使用，实际使用时间已经超过以前使用的高锰钢的使用寿命，目前仍在继续使用中。

The results show that the addition of certain manganese in high chromium cast iron leads to a re-partitioning of alloy elements between austenite and carbide and a dropping in equilibrium phase transformation temperature although it's inappreciable for the influence of manganese on mass fractions of every phase in this cast iron. There is about 87 percent ledeburite under thermodynamic equilibrium condition and 23 to 32 percent M7C3 type carbide under thermodynamic non-equilibrium condition in the microstructure of 3C-l5Cr-4Mn-0.75Si system high chromium cast iron. Furthermore, the improvement of austenite stability and hardenability of manganese alloyed high chromium cast iron may been expected because there is a substitution between manganese and chromium that has been suggested by thermodynamic calculations.

结果表明，锰虽然对高铬铸铁中的各相数量影响不大，但一定数量的锰存在促使合金元素在奥氏体和碳化物两相中的重新分配，并降低平衡相的转变温度；在平衡条件下3C-15Cr-4Mn-0.75Si系高铬铸铁中菜氏体数量约占87%，而非平衡条件下M7C3型碳化物数量在23%-32%之间，且奥氏体中锰铬互替现象保证了奥氏体的稳定性和加锰高铬铸铁的淬透性。
