Carburizing or carbonitriding and post - quenching and tempering of steel part
鋼件的滲碳與碳氮共滲淬火回火Standard specification for quenched and tempered vacuum - treated carbon and alloy steel forgings for pressure vessels
壓力容器用經淬火和回火真空處理的碳素鋼與合金鋼鍛件的標準規范The principle of multi - method and multi - parameter is suggested, which should be followed during characterizing microstructures of alloy steels by ultrasonic not method. ultrasonic velocity ( c, ) of transformation products through different heat processes of three steels was measured by high - accuracy ultrasonic installation. the velocity of quenched microstructure of 38crmoal is the lowest, which gradually increases with increasing tempering temperature between 200 ? and 650 ? after quenching process
利用ti - 40n高精度超聲波測厚儀，研究了超聲波在不同鋼種、不同熱處理轉變產物中的超聲波速度c _ 1 : 38crmoal鋼淬火組織c _ 1最小，淬火后在200 650范圍內進行回火處理時，隨回火溫度的升高， c _ 1逐漸升高， hrc與c _ 1之間具有較好的相關性；正火組織的c _ 1介於淬火后中溫回火及高溫回火產物組織的c _ 1之間。This paper analyzes and compares the ordinary heat treatment technology of q275 steel knuckle pivot pin with the quenching and backfiring technology
摘要分析、比較了q275鋼鉤尾銷普通熱處理工藝與鍛熱淬火回火工藝。For example, the quenching and quenching plus low tempered structure of 38crmoal are hard to be differentiated by velocity method and the principal frequency technique. it will be better if they are differentiated by the method of relative attenuation coefficient
38crmoal鋼的淬火與淬火+低溫回火組織，用聲速法和主頻率比較法都難以區分，最好的方法是比較功率譜譜峰特徵（幅度、數量、分佈） 。Standard specification for high - yield - strength, quenched and tempered alloy steel plate, suitable for welding
