  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.

  4. The result shows that tempered martensite has apparent lath character when temper is between 740 ~ 780, and the hardness of welded joint is 264 ~ 237hv, which can get better performance of the welded joint the lath character of martensite in welded joint disappears, and the carbide in the tempered sorbite of the base metal will aggregate when temper temperature is above 780, and the hardness and plastic property will reduce obviously

    結果表明，在740 ~ 780之間回火，焊縫硬度為264 ~ 237hv ，回火馬氏體板條特徵明顯，可以獲得優良的焊接接頭性能；回火溫度超過780 ，焊縫板條馬氏體特徵消失，母材回火索氏體中碳化物產生偏聚，硬度、塑性明顯降低。
