AISI 4340 강에서 Mo 을 대체한 W 이 강의 기계적 성질에 미치는 영향
김영길,박창남,강석봉 대한금속재료학회(대한금속학회) 1983 대한금속·재료학회지 Vol.21 No.11
The effects of substituting W for Mo on Mechanical Properties in a quenched and tempered martensitic AISI 4340 steel were investigated. The alloys containing 0.3-0.6 w/o W exhibited 35-75% increase at room temperature in impact toughness over the alloy containing 0.25% Mo after tempered at 600℃. However, the yield strength and the ultimate tensile strength were not increased significantly by substituting W for Mo. The mechanical properties were not improved greatly the W content exceeded about 0.4 w/o. Therefore it is recommended that 0.3-0.4 w/o W is suitable for optimizing the strength and the toughness when substituting W for Mo in AISI 4340 steel.
