Description

少镍无钴马氏体时效钢
本发明提出一种少镍元钴马氏体时效钢。
目前所采用的马氏体时效钢为18%Ni型,其中含Ni、Co和Mo等贵重合金元素占30%以上,我国是少Ni缺Co国家,马氏体时效钢在应用范围受限其主要原因是合金的成本昂贵,所以,减少Ni,Co等合金元素含量,降低钢的成本是目前马氏体时效钢的重要研究方向。
本发明的目的是针对目前Ni和Co金属昂贵,提出一种以我国资源丰富的Mn替代一部分Ni,去掉Co,即一种少Ni元CO的新型马氏体时效钢,达到降低马氏体时效钢的成本,扩大其应用范围。
本发明的目的是这样实现的:少Ni无Co马氏体时效钢有以下两种,第一种的化学成分重量百分比为:镍Ni:5-9,锰Mn:2-6,钿Mo:2-6,铝:Al:0.1-0.3。铈Ce:O.005-0.01,铁Fe:余量。第二种的化学成分重量百分比为:镍Ni:5-9,锰Mn:2-6,钼Mo:2-6.铝Al:O.1-0.3,铜Cu:O.2-0.4,铈Ce:O.005-0.01,轶Fe:余量。
本发明所得到的少Ni元Co马氏体时效钢在最佳热处理奈件下,可获得抗拉强度σb=1545MPa,

=1485MPa,δ=14%,ψ=40%,aα=51J/cm2,HRc47~48,其性能相当于美国名牌热模其用钢H13。
实施例1:合金成分的重量百分比为:镍Ni:6,锰Mn:3,钼Mo:3,铝Al:0.2,轶Fe:余量时,在最佳热处理工艺条件下,其性能中抗拉强度σb=1475MPa,屈服强度σf=1415MPa,ψ=45%,δ=15%,ak=55J/cm2,HRc=45。
实施例2:合金成分的重量百分比为:镍Ni:8,锰Mn:5,钼Mo:3,铝Al:0.2,铈Ce;0.01,轶Fe:余量时,在最佳热处理工艺条件下,σb=1480MPa, =1450MPa,ψ=40%,δ=12%,ak=50J/cm2,HRc=48。
实施例3:合金成分的重董百分比为:镍Ni:8,锰Mn:3,钼Mo:5,铜Cu:0.2,铝Al:0.2,铈Ce:0.05,铁Fe:余量时,在聂佳热处理工艺条件下,σb=1450MPa, =1400MPa,ψ=39%,δ=11%,ak=48J/cm2.HRc=45,
实施例4:合金成分的百分比为:镍:Ni:9,锰Mn:4,钼Mo:6,铝Al:0.2,铈Ce:0.005,铁Fe:余量对,在最佳热处理条件下,σb=1560MP,
