合金碳化物 meaning in English
alloy carbide
Examples
- The size of microalloyed carbides is very small and some is only 2 ~ 3nm . so microcrack extending can be restrained
并且,由于微合金碳化物尺寸很小,可达2 3nm ,对于微裂纹扩展有一定的约束作用。 - In the specimen of low carbon , ferrite with low hardness and a little pearlite is found ; and the specimen of high carbon is made up of pearlite and various alloyed - carbide
组织观察表明,碳含量较低的试样中主要是硬度不高的铁素体以及少量的珠光体;而碳含量较高的试样中则主要是珠光体以及各种合金碳化物。 - 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。
