用特种铸造法制成的新型碳化钨钢结硬质合金可以通过锻造改形。锻造改善了合金内部的不良组织结构 ,并使其硬度趋向均匀分布 ,冲击韧性也得到提高。
A new type of tungsten carbide steel hardened carbide made by special casting method can be transformed by forging. Forging improves the poor internal structure of the alloy, and its hardness tends to be evenly distributed, impact toughness has also been improved.
