Description
表1に示す成分組成となるように調整した溶湯を鋳型に注湯し鋳鋼を製造した。鋳鋼は、φ100×350とし、1000℃×2hrの熱処理を施し、炉内で冷却し、それぞれの試験片サイズに切り出し試験片とした。製造した試験片に対して315℃で2hr熱処理して最終的な合金を得た。
表2に示す成分組成となるように調整した溶湯を、φ100×350の鋳型に注湯した。この鋳塊を1150℃に加熱した後、鍛造して、φ50の鍛鋼とした上、1000℃×2hrの熱処理を施し、炉内で冷却し、それぞれの試験片サイズに切り出し試験片とした。また、実施例39及び40の熱処理は、鍛造前に1200℃の拡散処理を、鍛造後は800℃×2hrの熱処理を施し、水冷しそれぞれの試験片サイズに切り出し試験片とした。それぞれ製造した試験片に対して、315℃で2hr熱処理して、最終的な合金を得た。
