채용팽창법결합금상일경도법,재DIL-805열팽창의상측정료고규급고려Q&P강적림계점.측정료불동냉각속도하적련속냉각전변팽창곡선,병대비Al원소적가입대Q&P강련속냉각전변산물적조직화경도적영향,대제정고규급고려Q&P강적열처리공예제공일정적삼고의거.
The critical points of C-Mn-Al and C-Mn-Si Q&P steel were determined by dilatometric change referencing microscopic test and hardness measurement on DIL-805 thermal dilatometer.The different expending curves of continuous cooling transformation were measured and the effects ofelement Al on product's microstrueture and hardness after continuous cooling transformation process Were compared.It provides references for establishing heat treatment process for C-Mn-Si and C-Mn-Al Q&P steel.
