alterant
alterative
leavening agent
modifier
Examples
- Qualitative evaluation of molten al - si alloys by thermal analysis
过共晶铝硅合金细化变质剂的研究 - A green and permanent modificant for hypereutectic al - si alloys
一种过共晶铝硅合金的绿色长效变质剂 - When the content of w is 4 % or 6 % , m ( , c carbides increase distinctly despite of the major carbides of m2c and mc / m2c distributed along the crystal boundary in the solidification microstructure . the element of niobium can accelerate the formation of mc carbides and form the composite carbides of v and nb
扫描电镜和能谱分析表明，用1刀ti变质处理时，变质剂中的ti可以和钢液中的c生成大量弥散的n质点1汇作为异质核心促使了v 、 nb形成mc型碳化物。 - The boundary of ferrite has been clarified and fined by adding re into crsomo . the intergranular corrosion induced by solution chromium decreasing can be restrained for nb , v , ti combing carbon in the steel . the wear resistance of stainless steel can be increased for the precipitation of microalloyed carbides
其中，稀土能够净化铁索体晶界，并起到变质剂的作用，细化铁素体晶粒，改善不锈钢的韧性；铌、钒、钛能够与钢中的碳结合，减少固溶铬的损失，从而避免晶间腐蚀，同时细小微合金碳化物的沉淀析出可提高不锈钢的耐磨性。
