residual elements-
Abstract : for analyzing the residual stress distributing state within the weld joint, and its effect on the performance of welding structure, when welding the ferrite pearlite steel with the austenite steel, this paper develops a finite element program to compute the interface stress of two or over two material. finally, this program is used to analyze the mechanical behavior of heterogenic joint
文摘:為了分析鐵素體、珠光體類鋼與奧氏體類鋼焊接時，焊接接頭處焊接殘余應力的分佈狀態及其對焊接構件性能的影響，研製了可計算兩種或兩種以上材料界面應力的有限元程序，並用此程序分析了異質接頭的力學行為。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。The codex alimentarius commission is an international body which sets international guidelines on many elements of food safety, including pesticides residues on food

大多數樣品的cr 、 ni 、 co 、 sc等強相容元素含量較低，也暗示了形成鎂鐵質巖石的母巖漿應屬殘余熔融體。It was found that the interfacial bonding of 93w - ofc was both the joining action of ofc / w grains and that of ofc / ni - fe binders, whereas the joining of ofc to tc4 could be seen as the mutual intense diffusion effect between ofc / tc4 and as a result cu - ti intermetallic compounds were formed at the joint. the joining of tc4 - a1 and a1 - mb2 were also attributed to the result of diffusion between elements ti - al and al - mg respectively. on the other hand, residual thermal stress and stress - induced distortion were produced at the joint simultaneously due to the difference in thermal expansion coefficient of different welding " materials
研究表明， 93w與ofc的界面連接是ofc與93w中w晶粒的連接以及ofc與93w中ni - fe粘接劑的連接共同作用的結果； ofc與tc _ 4連接界面的形成是由於ofc與tc _ 4之間發生反應擴散，並由此在二者接頭處生成了cu - ti金屬間化合物的中間相； tc _ 4 - al的連接與al - mb _ 2的連接則分別是其基體元素ti 、 al之間和al 、 mg之間元素互擴散的結果，另外，由於熱膨脹系數的差異，擴散焊接后在不同焊件的接頭處存在殘余熱應力並由此引起接頭的形變。Test methods for determination of trace elements in coal, coke, combustion residues from coal utilization processes by inductively coupled plasma atomic emission, inductively coupled plasma mass, graphite furnace atomic absorption spect
