Compared with normal concrete, polypropylene fiber reinforced concrete has advantages in ductility, durability, fracture energy, impact resistance, abrasion, and so on.
HTMT significantly improves the ductility and fracture toughness of sintered steel and powder forging steel.
高温形变淬火显著改善烧结钢和粉末锻钢的延性和断裂韧性。
