在过去几年中,人们对不含贵重元素的抗氧化钢日益发生兴趣。Fe—Al合金抗腐蚀性能高,特别引起注意。几种Fe—Al为基的三元合金中,最有希望的是Fe—Al—Mn和Fe—Al—C系统。本文报导了由这些系统引导出来的Fe—Al—C—Mn和Fe—Al—C—Mn—Si合金的研究情况。四元合金是将铝加入真空熔化的Fe—C合金中,然后通入氦气,再加锰制成。下列成份已研究过:7—13％Al,20—40％Mn,0.10—1％C。铜液浇铸成63.5毫米直径的圆锭,然后热轧成15.875毫米的圆棒。进行不同温度(最高达815℃)的拉力试
In the past few years, people have become increasingly interested in non-precious elements of the antioxidant steel. Fe-Al alloy high corrosion resistance, special attention. Of the several Fe-Al-based ternary alloys, the most promising are the Fe-Al-Mn and Fe-Al-C systems. In this paper, the research reports of Fe-Al-C-Mn and Fe-Al-C-Mn-Si alloys derived from these systems are reported. Quaternary alloy is added to the vacuum melting of aluminum Fe-C alloy, and then leads to helium, plus manganese. The following ingredients have been studied: 7-13% Al, 20-40% Mn, 0.10-1% C. Copper liquor is cast into a 63.5 mm diameter ingot and then hot rolled into 15.875 mm round rods. Rally tests were performed at different temperatures (up to 815 ° C)
