Based on the analyses on mechanical properties, microstructure and fracture of - the microalloyed steels socrv with various heat treatment technique, it can be affirmed that various fractures arttribute to various mechanism, we can draw conclusion that the strength and toughness of microalloyed steels 50crv will be increase simultaneously by optimal heat treatment technique. to illustrate the mechanism of the strength and toughness of microalloyed steels socrv, we designed the comparative experiment and observed the microstructure of the sample which occurred at different quench and tempering temperature and different tempering time. the last experiment results were determined by the four factors : fined microalloyed elements grains, the decompound of martensite, martensite transformation of remnant austenite and the second phase precipitation
為解釋微合金化50crv鋼強韌化機理,本文通過對不同淬火溫度,回火溫度,回火時間下的力學性能指標的對比及顯微分析,認為微合金元素的細化晶粒,馬氏體的回火分解,殘余奧氏體的轉變,第二相的沉澱析出共同決定了微合金鋼的強韌化情況,特別是由於微合金元素的存在,其細化晶粒及其碳氮化物的沉澱析出,導致鋼的良好的強韌性,並且如果工藝滿足第二相的沉澱析出強化大於回火馬氏體分解引起的軟化效應,會在硬度曲線中產生明顯的二次硬化現象。Suspended solids including fine particles and colloids cannot be removed efficiently with gravitation sedimentation ; they are removed using centrifuge, dissolved air flotation, diatomaceous earth filtration, coagulation sedimentation plus rapid sand filtration while dissolved solids are removed with ion exchange, ultrafiltration, activated carbon adsorption and chemical oxidation
懸浮固體之去除包括微顆粒及膠體物,無法以重力沉澱之物質,可採用離心分離機、空氣浮除法、矽藻土過濾法、混凝沉澱加快濾池等去除之。而溶解性固體去除則採用離子交換法、微細孔濾膜過濾、活性碳吸附以及化學氧化等去除之。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,稀土能夠凈化鐵索體晶界,並起到變質劑的作用,細化鐵素體晶粒,改善不銹鋼的韌性;鈮、釩、鈦能夠與鋼中的碳結合,減少固溶鉻的損失,從而避免晶間腐蝕,同時細小微合金碳化物的沉澱析出可提高不銹鋼的耐磨性。The effect of amorphous hydrated ruo _ 2 power production is discussed here, including : selection and ratio of solvent, selection and concentration of precipitator, terminal ph of titration and anneal temperature and time of colloid. research indicated that terminal ph and anneal temperature are the most important influence factors on physical and electrochemical properties of amorphous hydrated ruo _ 2 power
