摘要: 對經過熱愈合處理的16Mn鉆孔壓縮試樣的內裂紋愈合形態、愈合區域組織結構、顯微硬度進行了測試與分析．掃描電鏡分析結果顯示,愈合區內精細組織主要為鐵素體,并存在許多大小為幾百納米級的多邊晶塊．維氏硬度測試結果顯示,出現在愈合區鐵素體組織的維氏硬度高于基體區鐵素體組織,其可能原因是愈合區中出現的多邊晶塊結構所引發的強化．

Abstract: Healing processing of 16Mn steel samples was carried out. The healing area of internal cracks made by compressing a drilled hole was observed and analyzed. SEM analysis displayed that the fine structure in the healing area is mostly ferrite and there exists many polyangular grains of several hundreds nanometer. Vickers hardness tests showed that the hardness of ferrite in the healing area is higher than that in the matrix, which may result from strengthening of polyangular grains.
