Abstract
【解決手段】高温耐摩耗材の素材となる鋳鋼の組成を、C:0.2〜0.5wt%、Si:0.2〜1.5wt%、 Mn:16〜24wt%、Cr:12〜20wt%、N:0.1〜0.5wt%を含有し、残部がFe及び不可避的不純物からなるものとした。このように、高価なNiを含有しないものとすることで、安価に製造可能となり、Mnの含有量を増やすことで、高温摩耗性を確保することができる。
【選択図】なし
Description
Cは、高温強度及び耐摩耗性の向上に有効な元素であり、強度及び耐摩耗性を確保するために0.2wt%以上含有させる。一方、含有量が多くなると靭性が低下するため、靭性不足による割れが生じないように、上限は0.5wt%とする。
各種試験には、まず、表1に示した組成の溶解金属を30tYブロック用の砂型に注湯して得られた鋳放し品を、下記の条件で熱処理し、必要なサイズに切断して試験片を作成した。
(熱処理条件)
加熱温度:1100℃
加熱速度:100℃/時間
保持時間:5.5時間
冷却方法:水冷
