摘要

研究了氧化铝颗粒在 15° 和 90° 冲击角下对正火（N）和双相（DP）低碳钢（0.08% C）和中碳钢（0.42% C）的磨损情况。DP 钢是通过在 745°C 下对低碳钢和中碳钢进行不同保温时间（2、3 和 4 分钟）的临界退火热处理，然后进行水淬，从而在结构上形成不同数量的马氏体。结果表明，低碳和中碳双相钢的硬度和 UTS 随马氏体含量的增加而增加。在 90° 角时，材料会通过开裂、形成凹坑和低角度切削去除，而在 15° 角时，材料会发生犁状切削。

Erosive Wear of Dual-Phase Low- and Medium-Carbon Steels after Quenching from the Intercritical Temperature Range

The wear of normalized (N) and dual-phase (DP) low-carbon (0.08% C) and medium-carbon (0.42% C) steels under air-jet erosion at 15° and 90° impact angles of alumina particles is studied. The DP steels are produced via intercritical annealing heat treatment of low- and medium-carbon steels at 745°C for various holding times (2, 3, and 4 min) followed by water quenching, which results in formation of a varying amount of martensite in the structure. The results indicate that the hardness and the UTS of the low- and medium-carbon dual-phase steels increase with increase in the martensite content. Material removal occurs by cracking, crater formation, and low-angle cutting at 90°, whereas ploughing and chipping of the material occur at 15°.
