Colette Allibert博士说 ,虽然 WC— Co硬质合金成分种类不多 ,但是由于跟氧杂质或炉内气氛的反应导致碳含量变化所产生的影响还没有完全弄清。通过添加钒或铬来控制晶粒长大的说法更加容易使人走入误区。作者在她领导的研究小组所获得的实验结果和计算结果的基础上 ,着手阐述? Colette Allibert, PhD, said that although the WC-Co cemented carbide composition is small, the impact of changes in carbon content due to reaction with oxygen impurities or furnace atmosphere is not fully understood. By adding vanadium or chromium to control the grain growth is more likely to make people into the erroneous. On the basis of the experimental results and the calculation results obtained by the research group led by her, proceed with elaboration?
