淬火不足 的英文怎麼說
中文拼音 [cuìhuǒbùzú]
淬火不足
英文
under hardening-
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。We also have advanced heat treatment devices : 6 net strip quality control production lines, 4 quenching production lines, and 22 equipments including trunk oven, well oven, vacuum ion nitrogen oven, vacuum quenching oven, high frequency quenching oven and etc. the completeness of equipment and technical expertise can meet the different requirements of our customers
公司還有先進的熱處理設備：網帶調質生產線6條，正火生產線4條及箱式爐井式爐真空離子滲氮爐真空淬火爐高頻淬火爐設備等22臺。全的設備和專業的技術能夠滿足不同客戶的各種要求。Traditionally, pump manufacturers have specified hardened martensitic stainless steels for critical wear parts, maintaining a 50 - 100 brinell hardness difference between rotating and stationary components as experience has shown this is adequate to prevent galling
通常，製造商採用特殊的淬火馬氏體不銹鋼製造關鍵磨損件，旋轉件和固定件的布氏硬度分別保持在50 - 100 ，經驗表明，足以防止發生咬合現象。The research results on laser hardening of the fibre - cutting roller showed that using laser surface hardening process instead of thermal spraying to strengthen the surface of fibre - cutting roller of 4crl 3 stainless steel is practicable. not only this technique overcame the disadvantage of larger heat distortion by using thermal spraying but also possessed the advantages that the operation is simply and that expense is easy
過絲輥激光表面淬火的研究表明，選取恰當的工藝參數對過絲輥表面採用激光淬火替代傳統的熱噴塗是切實可行的，該方法不但能夠克服熱噴塗方法中工件變形大的不足，而且工藝簡便、成本低廉，實用性強，具有明顯的經濟效益和推廣應用價值。分享友人
