  1. 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。
  2. We apply the system to the ultra - fine grain steel welding, the simulated mean grain size in cghaz agreed well with the corresponding independent experimental data. in this paper, three factors influencing the grain growth, the steep temperature gradient in haz. the grain boundary liquid and the precipitates particle, were studied specially using mc technique

    研究表明溫度梯度造成的「熱釘扎」現象和晶界液化現象都對靠近熔合線附近的晶粒長大有明顯的阻礙作用，對最終的晶粒大小分佈有重要的影響：而800mpa超細晶粒鑰中的tin粒子山于溶解溫度高，抑制奧氏體晶粒長大的效果十分顯著。
  3. Abstract : the crystal structures obtained by static solidification and vibration solidification were compared. it was showed that, in the case of vibration solidification, the orientation growth of the columnar crystal was not obvious, the equiaxial crystal appeared more early. the grains of both types of crystals were quite fine, hardness in the full section was relatively high, and the hardness distribution was uniform. in the former case, the solute segregation in dendritical austenite more severe, and there were lumps of distortion inclusion

    文摘:對球鐵金屬型靜凝固與振動凝固的結晶組織對比表明：後者柱狀晶方向性生長較弱，等軸晶出現較早，且兩者的晶粒均較細，全斷面硬度較高且分佈均勻；前者枝晶奧氏體內溶質偏析大，有畸變夾雜團塊。
  4. The combined effect of v and re can delay the dynamic recrystallization, refine the grain and second phase particles, and promote the precipitation of v ( c, n ) considerably

    釩和稀土復合微合金化有更強的推遲形變奧氏體動態再結晶，抑制奧氏體晶粒長大和細化晶粒的作用。
  5. The experimental results show that decreasing rolling temperature is helpful in getting the fine austenite grain size in comparison with the conventional rolling deformation temperature, which is a kind of potential technique for improving the general properties of the workpieces

    實驗結果表明：降低軋制溫度有利於得到較細小的高溫奧氏體晶粒，是一種提高工件綜合性能的新工藝。
  6. In this paper. monte carlo ( mc ) technique was used to simulate the grain growth in heat - affected zone of an ultra - fine grain steel

    本文採用montecarlo （ mc ）模擬技術對超細晶粒鋼鐵材料焊接haz的奧氏體晶粒長大進行了研究。
