軟中碳鋼 的英文怎麼說
中文拼音 [ruǎnzhōngtàngāng]
軟中碳鋼
英文
soft medium carbon steel-
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。It is applied to smelting the carbon steel, alloy constructional steel, stainless steel, copper, aluminum, gold, silver, niobium and tantalum etc. the technology of our intermediate frequency smelting equipment is ripe
它適用熔煉：碳素鋼合金結構鋼不銹鋼銅鋁金銀以及稀有金屬鈮鉭合金等。我公司生產的中頻熔煉設備電路技術成熟微機控制，工作穩定，軟起動，成功率高。Soft medium structural steel
