查询词典 cast iron

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。

The microsturcture characteristics of M2 cast-strip were studied with such experimental methods as metallographic analysis, SEM, XRD and TEM[0]. The effect of sub-rapid solidification on the size, type and distribution of eutectic carbides in M2 cast-strip was analyzed. The effect of heat treatment temperature and its holding time on the eutectic carbides in M2 cast-strip was explored. The eveolution of metastable phase of M2C eutectic carbide during the heat treatment period and the decomposition dynamics concerned were researched. The M2 cast-strips were rolled into thin strips and the effect of deformation ratio on carbides in M2 cast-strip was examined. Then these thin strips were comparied with those that were produced by conventional technology on carbide, hardness, red-hardness and bend strength. At last the rolled M2 cast-strips were made into saw blades and their cutting performance was experimented on in tools factories and then compared with that of similar products produced by conventional technology.
