Abstract
0.4wt%C steel added with V and/or Nb were forged and followed by air cooling. The structure-property relationships were examined and multiple regression analysis was conducted to quantify the magnitudes of effects of microalloying elements on the properties of the steels. All material's tensile strength are greater than
0.4wt% C을 함유하는 기존의 기계구조용 탄소강에 V과 Nb을 단독 또는 복합으로 첨가한 열간단조용 비조질강의 기계적 성질을 조사하고, 미세조직과 셔출물의 분포 및 형상을 관찰하였으며 첨가원소의 영향을 정량화 하기 위해 중회귀분석을 행하였다. 인장시험 결과 모든 재료의 인장강도는
